Pilates Part 1 of 3

Hello all!

I'll get straight into it-- pilates is where it's at. It's a great cross-training tool to use to strengthen your body, especially your core, and better yet, it is a no impact exercise tool. It's so great, in fact, that I will devote three separate blogs to this awesome stuff, for lack of a better term, because it is 8 pm on a Sunday after all. :)

Pilates has been a recent discovery of mine, along with yoga. These were two things I never had time to do as an athlete, and unfortunately, I wish I had done it during my tennis days, as I think it would have made me a stronger, better player. So let's talk about pilates. Pilates was originally made by a dude called John Pilates, who created machines specifically made to help recovering injured soldiers as physical therapy to strengthen their whole body without having to get up and walk around. It has since morphed into a popular gym experience, most of which occurs on the mat, even though true pilates is based off of machines, like this:
   This machine looks scary, but in reality it's easy to use and can strengthen every muscle in your body with different movements. But because these machines are A LOT of money, and because even going to classes with these machines are A LOT of money, most pilate-ers are mat fanatics, because all you need is, well, a mat. Or something squishy to sit on.

So the basics of pilates include terminology that you'll here thrown around, like pelvic floor muscles, which sounds very fancy, but in fact are the muscles you contract when you really need to pee and you're holding it in. Pilates stance is when your heels are touching each other and your toes are facing out, like a ballerina. One of the more likely things you'll hear on the mat is the sitz bone, which at first I had no idea how to spell, so I googled sitz, and apparently that's the correct spelling since it corresponds with the bones you "sit" on! More clearly, the sitz bones are the bones at the bottom of your pelvis. You'll always be reminded, including here, to align your sitz bown as close to your heels as possible, and this may not make sense at all. What you want to make sure, essentially, is that your not laying directly on your butt cheeks. Instead, you want to align your body so the weight is distributed fully across it, which means you'll probably have to adjust your butt (or sitz bones) by arching your back a bit back and forth. You should be laying down straight, but with a natural curve at the base of your spine. This is called a neutral pelvis-- an arched back or flattened back puts more pressure on your spine. In some pilates moves, you have to work to keep your hips and back in neutral.

Tabletop is another term that means you are laying on your back and have your knees up and together in a 90 degree angle. This is a resting position in pilates. Kind of like her:

   The only difference with tabletop and what this girl is doing is that your arms would be down and resting. What she is doing is called hundreds, which represents the breath count (one one hundred, two one hundred, ect.). When doing hundreds, you can either keep your legs in tabletop or straighten them, all the while pulsing your arms up and down, but not touching the mat. Straightening your legs is obviously harder, but targets your lower belly better. For those of you with the dreaded belly pooch, these are fantastic for strengthening your lower abs.

Let's talk about some more exercises. This one below doesn't have a name that I can recall, but is a good side muffin burner. Notice how the feet are positioned side by side, and the arm is aligned (or should be aligned) with the shoulder so as to not put too much pressure on the wrist. The other arm is straight up. There are two variations of this exercise. The first one is simply balancing, and the easy of the two. The other variation is to use the arm that is already up above your head, move it through the space created between your legs and other arm slowly until you reach the opposite end of your mat, and then slowly bring it back up again. If you need a visual, think about this guy with the red shirt in the picture. His left hand is high up in the air, and he would move this arm through the opening created by his arm and legs, turning his body but not falling, and reach it to the right side of his mat.

Then there is this
girl on the right.
She's doing an extended leg hundred, or she could be reaching up to touch her legs and then bringing everything back down, which are two pilates exercises that are great for the back and lower abs.

The image with the green mat and the girl in black is both a stretching and strengthening pilates move. Digression: pilates rarely makes you sore, because most of the exercises are both strengthening and stretching. Pretty awesome! Anyways, she is keeping both legs straight, bringing one leg up at a time and pulling her leg closer to her for a hamstring stretch using her hands. You can grip like she does, by her ankle, or for those of us who are not that flexible, you can grab behind your knee, but make sure you keep your leg straight. The opposite leg will always hover above the ground.

Finally, the exercise below is a good hamstring and butt strengthening one. Notice that she lifts her leg up-- you can start with keeping both legs on the ground and lifting your pelvis. If this is too easy, bring your feet in closer to your body and lift up on your toes, then lift your pelvis. Still too easy? You're reading for her pose, which necessitates lifting one leg up at a time. You can either pulse here, try and stay here as long as you can, or lift and switch legs each time. 

Till next time, adieu!

Thoughts on Thoughts

Sorry about the late post! I've been in Orlando this weekend getting some teaching professional development in. Chris Crutcher was one of the best speakers; he's an author and a child therapist who writes about his patients and ends up being banned from schools everywhere because of bad language. Funny enough, many students who read his works end up truly finding themselves as people and connect with the book at an extremely emotional level. It got me thinking that tennis is very much an emotional struggle, and many kids go through competitive tennis still mustering up the courage to step out on the court, even though they cannot control their thoughts.

I was one of those players. My entire tennis career, I can say now, made me the person I am today, and taught me many things other experiences don't have the capability of doing, even school or education through books. I struggled with my mental approach to tennis throughout my career. I was a very thoughtful player, in the sense that I had too many thoughts in my head while playing, from "That was a pathetic shot, Katie," to "Yes, I won that point, now let's get it back to deuce because this is an important game." I tried to shut off my mind loads of times, but realized that this was my kryptonite. There were times where I had a perfect balance of thought that didn't drive me crazy. Then there were times that this balance would slip, and my thoughts would pile up in my head like water bubbles boiling when a kettle of water is on the stove, finally boiling over the pot, and exploding (quite literally) my mind, creating a self collapse that would snowball and snowball. Who's thinking about tennis when your mind is fighting with itself?

There were many things that worked, and many that didn't work to help me get over this mentality crisis. Some things would work sometimes and not others. Breathing helped here and there, but sometimes it wouldn't. A coach talking/yelling at me sometimes brought me back to normalcy, others it only accelerated the boiling water approaching the top of the kettle. I'd repeat the mantra in my head that my dad, and my one true coach, always told me: "Don't try too hard." This is what I repeat now as a coach myself to other players. I tell players that I've been where you've been. Racquet slamming on the ground in frustration are unacceptable to parents, but understandable for me. Not saying that it's not unacceptable, but sometimes it takes someone who's been there to explain and be there through the range of emotions tennis (or any sport for that matter) courses through your body.

This blog isn't for answers, it is for explanation. I can't tell you what to do to "fix" the way you approach the game of tennis, but I can tell you that I've been there, like many of the coaches at Seminole High Performance, and try and give you a tiny look into my brian and into my thoughts. I can tell you this; the mental aspect of tennis is a continuing process. There are professional tennis players that are ranked top ten that struggle sometimes with their approach to the game. This isn't something you figure out and then you're good. It's a never ending process of improvement, and sometime, failure. Some things that worked for me may make you worse on the court, and some things that didn't work for me may be your salvation.

If you stick through it and don't give up, you'll emerge on the other side a more knowledgable and mature person. I know understand why my mom always told me that sport is the game of life, and that you learn how to approach life and its pressures through the game of tennis. The sport mimics life. Whatever happens, dust yourself off and get back up. It will make you stronger when you find your ground. :)

Ssttretcchingg

I know, clever stretching of the title stretching, huh?

For the tight-legged, wound-up tennis players out there, I know how you feel, I've been there before. I actually only stopped being stiff (especially my hamstrings) after I started doing yoga, which is amazing and I recommend it to all tennis players.

Yoga strengthens the muscle at the same time as you stretch it; it encourages the muscle to lengthen, creating mean lean machine-like muscle (I have awesome rhyming skills, don't you agree?). It also encourages proper breathing and relaxation, depending on the type of class you take. Certain classes, like yin yoga, focus on the lengthening and stretching of the muscles; a good class for tennis players with stiff legs and backs to help them loosen up without much focus on strengthening. However, the best yoga classes stretch and strengthen, and opposite from common belief, are quite a workout. There are several varieties of strengthening/stretching yoga, including but not limited to "turbo," "Ashtanga," and "Flow." Hot yoga is another great class you can go to, where the room is heated to a toasty 110 degrees. You'd want to be careful if you've never been in a sauna or steam room before because it does get a bit uncomfortable, but it also relaxes your muscles for a deeper stretch.

Now that you know the classes I recommend, let's go through some poses that you can do on your own. Keep in mind these are the starter yoga poses, and you could always adjust to your preferences.

The Child's Pose: The basic yoga pose requires you to lay down on your mat with the objective of getting your butt to your heels, which takes some time and practice.

The next pose is called the cobra position, and this stretches out your abs. Make sure you keep your palms flat and stretch your neck upwards, with your nose tracing a line up to the ceiling slowly. For these poses, you want to be able to keep them for at least one minute each, preferably at least three minutes for a deep ligament stretch.

To the right you will see a very common pose called the downward facing dog, or downward dog. This stretches both the lower back as well as calves. The goal is to get your heels all the way to the floor. Make sure your back is straight, your palms spread out at the outer corners of the mat, and that you aren't adding unnecessary pressure on your wrists. Keep your feet about a foot apart (Feet a foot! Lol! :)), and if you want to add more stretch, pulse your knees forward and back and walk it out to get a deeper stretch in your calves.

Fire log is a deeper, more advanced pose. While it looks simple, it's hard to get your foot on top of your opposite bent knee. There are several factors of this pose that you need to know. First of all, while the picture is "picture perfect," you may not be able to get your knee all the way down on the first try. It also is nice to have something to prompt you up underneath the knee that is closest to the ground. You can use a blanket, a pillow, or a yoga block. This stretch is fantastic for the hip flexor, a muscle notoriously stiff for tennis players, particularly boys. For a deeper stretch, lean forward into the foot that is above your opposite knee.
 
A simpler stretch that helps both the hamstring and the hip flexor is the stretch to the right. Your goal is to work your chin towards your knee; eventually you'll be able to reach your forehead to your knee like the lady below. You want to be careful not to over stretch your hamstring by pushing yourself too hard the first times you start yoga stretches. Your first goal should be to touch your shoelaces with your fingers (or your toes if you're barefoot)!

Another good hip flexor stretch is to the right. You are reaching your chest towards you bent knee, trying to keep your back straight as you do so. You can also reach up with your hands, clasping them together, creating a straight diagonal line that starts with your clasped hands and ends with your outstretched foot. This a similar type of stretch that also strengthens at the same time, and is one of the few varieties of warrior stretches.

The pigeon pose, seen below, is a great quad stretch. A variation of this pose that is more advanced is to lay your front leg down, leaning your right front leg towards your left wrist. That made no sense. :)

I'll try again. Laying down completely with your left leg straight behind you and your right leg bent at an angle with your heel facing towards the left wall, use one of your hands to pull your left leg up into pigeon pose with your right leg still on the floor. This allows for a deep hip stretch while still working on your quad.

The man on the right is in a deep quad stretch that I only recommend for more advanced and flexible players. Start with your knees at either end of your yoga mat, slowly sink backwards, using your hands to guide you gently to the ground. Everyone can try this, but most likely you won't get all the way down to the ground on your first try. Your goal would be to get down to your elbow prompting you up at first.
 









The Warrior pose is a great strengthening pose which enables all leg muscles in both a stretch and a strengthening position where they are holding the rest of your body up. Keep this pose for at least forty five seconds, but start with thirty if you can't handle 45 right away. Doing this in front of the mirror is important so that you can keep your arms level and keep one foot pointed forward while the straight leg is pointing sideways.

Finally, another hip flexor stretch that is very relaxing is below. This opens up your hip flexors and allows you to breathe deeply in and out, relaxing your body as your hips open up. Start with your heels touching a bit further out, but as you get more flexible and want a deeper stretch, move your heels closer and closer to your body


On that note, keep in mind that yoga is a practice that allows you to relax, stretch, and help out your tennis quite a bit. If you have any questions at all or want to know more, write a comment and suggest a new blog topic, or ask me a question about yoga (or anything!). 

Namaste!

Injury Prevention


Ouch! The classic way of starting a blog on injury prevention. That being said, I rarely meet a competitive tennis player that has never, ever had something hurt. More than being sore- don’t be a baby. Tennis players have the luxury of being one of the few sports that cause the most self-inflicting damage. While we aren’t tackled by our opponents and don’t take our gloves off in order to punch each other (I guess hockey would be a fairly uncommon sport in Florida, my apologies), the wear and tear of our sport can do some harm if precautions aren’t taken. Take, for example, the continuous impact of the hard court surface and what it does to a player’s knees and shins. Or, think of the probability of twisting an ankle when running in almost every direction with short bursts of explosion and the necessity for a quick change of direction that the sport requires. Then, take the grueling impact on shoulders, elbows, and wrists that is required to swing a racquet, below and above your head. Back, abs, and hips have some liability when overuse and a slight move in the wrong direction can tweak those large muscles. Pretty much, we’ve hit every single part of our body in tennis that can eventually succumb to painful injury- because tennis is a year round sport, oftentimes tennis players are seen playing through numerous injuries. Bad. Very, very bad.

But that doesn’t help, does it, just to say playing through injuries is not a good idea. Once injured, RICE is the best option- rest, ice, compression, elevation. Sometimes, especially when muscles spasm, warmth is better than ice. Applying a heat pack to relax the muscle can be beneficial. If the urge to play is so great that even an injury does not stop you, wrapping the injury is an option. This prevents the limb from moving in its full range, and adds compression that helps inflammation subside. That being said, you kind of need to know what you are doing in order for the wrap to work. Just rolling up your ankle in globs of athletic tape won’t do anything. If you don’t have an onsite trainer (all tournaments have them), handy dandy Google can help you with the wrap of your choice. Odds are, your coach will know how to wrap the injury too. Other, more obscure ways of treating injuries include electric stimulation (pads that adhere to your skin and send electric pulses to the area to a) relax the muscle and b) send more blood flow to the area), grastin (metallic stubby knife looking things that are used by a certified trainer to enhance blood flow to the area- as a person whose stubborn injuries were alleviated by this method, I am a huge perpetuator of this method, although it is painful), and orthotics (again, as a person with weird flat feet, I can attest to the benefits of custom orthotics that are placed into the sneaker to lift or support the arch in the foot. This can even change your gait and posture). 
Contrary to many beliefs, stretching can sometimes do more harm than good to an injured muscle. It’s one of the best ways to PREVENT injury, but not a great idea to do with, say, a pulled muscle. A pulled muscle is already, well, stretched. Spasms, however, do need to be stretched. Exercising also doesn’t seem to be a viable solution for an injury, but can be surprisingly helpful when injured. If, say, I pulled my quadriceps, I would strengthen my hamstrings, the muscle that works in tandem with my quadriceps, in physical therapy. Speaking of balance in muscle strength, keep in mind when working out that any muscle workout you do has to be in balance with the muscle that it works with. For example, while rock solid abs are both attractive and beneficial for tennis, strengthening your abs without strengthening your back muscle can be very dangerous- you are setting yourself up for a very bad strain to your back. A weaker muscle that works in tandem with a stronger muscle is at risk of injury constantly because the stronger muscle overworks the weaker one. Another thing to keep in mind is that tennis players naturally gain strength in certain areas, and so a gym workout should focus on those areas that need improvement off the court. Some of these areas include pectoral muscles, which are shortened by the strength in a tennis player’s shoulders, and hip flexors and the groin muscle, both of which are often underdeveloped in a tennis player compared to their quads and hamstrings (hamstrings, by the way, are often much weaker in tennis players than their quads- at a much younger me point in time I was able to lift 80 pounds with my quadriceps but only 40 with my hamstrings, a worrisome difference).     

Injuries aren’t any fun. That’s why you should be reading this next section, which is on injury prevention. Injury prevention is the unsung hero of tennis, and unfortunately is often left out of grueling practices where it is most necessary. There are certain things that you can do while you are playing that will help both your game and your fitness and injury prevention. This is a very simple idea- the fitter you are, the better protected you are from injury. A strong muscle will take longer to fatigue and will stay under control for longer. It’s important too though not to overwork a muscle, since this shortens the muscle instead of creating the long and lean but strong desired effect. Other things to prevent injuries, in laundry list style (digression in parentheses- why do they call it a laundry list? I’d think it would be more of a grocery list, wouldn’t it? Anyways…):
·       Stretch (not for two seconds on each leg- at least 20 minutes with each stretch lastly around 15 to 20 seconds at the least)
·       Yoga (aka a long stretch- it builds stamina too!)
·       Keeping your center of gravity low (or, in layman’s terms, bend your knees!)
·       Maintain correct technique on all shots
·       Ice tub (for overworked muscles and cramping)
·       Hydrate (dehydration in a dilapidating injury), preferably with coconut water or Pedialyte (see my nutrition blog) 
·       For the sake of your tennis game, your mental state, and your physical well being, if something hurts even though you took the necessary steps to help it (ice, compression, ect.), take a break. It’s better to take two days off after a pulled muscle then playing through it and having to take 6 months off for a tear. I’ve seen this happen to tennis players and I’ve had it happen to me as well. No matter what you have to be true to yourself and your physical well being- that’s more important than a tennis match will ever be.
And on that point, tootles until next time!

Learning & Coaching

Every now and again I think of my role as a coach, and the role of a coach in general for the learner of tennis. Being a teacher in school, it's important for me to reflect on my practices, but seldom do I reflect on my experiences as a coach. Because coaches aren't perfect either.

I first look back at how wonderful a job my parents did as my coaches, through the tears and fights and sweat, that made me a champion, and that continues to make my mindset and work ethic stand out from amongst my peers in many aspects of my life. I think about the passion they have for tennis, and the passion they vicariously instilled in me.

I think about what I've done as a coach, the students that I've taught, the shots I've made better, and I realize it's so much more than a shot or the game of tennis, just like in the classroom it's so much more than a novel or a good poem.

So I've complied a list. You know I love lists. But this list isn't just for you, it's reminder for me also, a reminder for me that I coach for a reason bigger than myself, and I hope one day it'll be a reminder for others who are in charge of children's learning and growing, so that they will always come out as a positive role model in someone's life.

Here it is; the list. A coach:

1. inspires a child to play tennis.
2. motivates; it's always easy to motivate a good player or a well-behaved child. But it is the one who struggles and who may have outbursts that needs the most motivation.
3. teaches discipline and routine; the child learns what is expected of them and what consequences await them if they do not follow through. Many believe that this may be strict or unfair, but it reality it gives kids wanted structure.
4. says the right thing at the right time, even if that right thing is saying nothing at all.
5. is a good listener.
6. is a role model at all times.
7. supports not just the player, but also his or her family and support system, and helps steer that support system to be a positive influence in the player's game.
8. notices the little things, whether it be a new haircut or a child's deteriorating attitude.
9. just once throughout the day, makes the child smile, and reminds them that tennis isn't everything.
10. is positive the majority of the time, and only negative when absolutely necessary.
11. let's the little things go.
12. loves what they do.

Doubles Blog

Hello world!

I know, I know, I'm a day late. Sorry! But I have a good excuse. I sat and graded 8th grade projects from 1 to 9 pm. Yeah, my brain was fried. Now it's unscrambled a bit! :)

Some doubs tips:


Your initial reaction when someone else is on your side of the court is “Get off my side of the court, fool!” However, if you’re playing doubles, this may turn slightly problematic if you kick your partner off the court. Now you have to tie the hypothetical umbilical cord and remember that without teamwork, you pretty much stink at doubles. Being aware of where your partner is beneficial, say, if they decided to throw a short lob to the opponent’s volleyer and your still at the net. Movement together is essential- two volleys are scarier than one, and two people in the back allows for a better grapple at defense. Yes, grapple is a not only an awesomely cool word, but it also happens to be a fruit- a cross between a grape and an apple- there’s your fun fact for today.

Back to grappling (even more awesome than grapple!) with doubles. Let’s talk positions. I couldn’t tell you how many times I’ve seen someone (usually girls, sorry) hugging the doubles alley, knees shaking from fear. The partner in the back has to cover about 80% of the court- don’t worry, your partner’s got that other 20% on a leash (Not so good metaphor/attempt at anecdote)! Truth is, there is not only “holy” position in doubles when the point is being played out- actually, it would be more honest to say that the “holy” position would be none at all. The more you move at the net, the more pressure the opponent feels to hit a better shot, and the higher the chance that they will make a mistake or that you (the volleyer) poaches. Yes, like an egg in boiling water. Or illegally hunting game (I guess that’s a bit better than an egg).  Never really understood why they (tennis-terminology inventors) called it poaching, but nevertheless…

Back to grappling (!) with the volleyer’s positioning. Again, there is no set place to stand for the volleyer during the point, but there are rules to help you make the most of doubles when your partner’s serving or returning. When your partner’s serving and you’re at the net (and you better be- don’t you dare go to the baseline, even if your partner’s serve travels 2.7 mph), you should be smack in the middle of the box. I hope I don’t have to tell you what box I’m talking about, partially because I’d feel silly explaining (the little one?), and partially because you’re just plain silly yourself for not knowing what I’m talking about. So there. Anyways- help your partner choose where the serve is going- if out wide, be ready for the down the line shot, and if body or T, be ready to poach (like an illegal hunter J). Encouragement is always nice- no one wants to hear “Can you hit the ball harder than 2.7 mph?” or “Your serve is frankly quite terrible.” You laugh, but there are people who actually say those things.
The returner’s partner. So say you’re at the net and you’re partner’s returning. It’s okay if you’re at the net, but if the opponent has a good serve, and the opponent’s partner likes to poach, you’re shark bait (or illegally hunted meat?). It’s okay to say back on the first serve to avoid that situation, but if you have a partner who has an awesome return, you should be standing a tad bit to the right and back of the middle of the box (the small one). So, you should be about a step from the service line and to the right of the middle of the box. This position does a couple of things- it puts pressure on the server, and it puts pressure once the returner hits back to the server- it allows for you to poach more easily as well. Try this position out in practice- your partner should be comfortable with you standing there before you try it out in a match, because you would potentially be in the trajectory of the ball if your partner can miraculously angle the ball off of a serve. You’ll be fine, don’t worry- you have to reassure your partner of that too. Calling the return is also a good doubles tactic- knowing where the ball is going off of the return can help you feel more comfortable at the net, especially if the return is going down the line. Speaking of which, some coaches believe that going down the line is taboo, but keeping your opponent honest (think illegal hunter) is a good doubles tactic. That being said, there is a reason why it’s considered taboo sometimes- it’s hard to hit and easy to react to once you expect it. Once every game is plenty enough. As the returner, it’s important that a high percentage of returns go crosscourt- this is a high-percentage play and involves your partner at the net into the point more.      
Say you’re the server- high percentage first service is key. If you have to kick your first serve, do it. Kick serves, by the way, are essential for doubles play. It allows you to have enough time to get to the net for a serve and volley and is consistent yet aggressive. Make sure you stand wider on the baseline and identify the weaker side early one. A body serve cuts off any angle that the opponent can hit, so lots of body serves can be used. Stay tuned for more “advanced” positions like the “I” formation and the “stack” formation. 

 Remember, don’t be the person cowering in the corner of the court and letting your partner do all the work for you- man up and make like an egg!

Core

Hey world!

Let's get straight into our new blog, working on abs!


I have never met someone who decides that they are okay with being an oompa-loompa. Considering mass advertisements with flat abs and good-looking bodies, the American mind has been warped by media and what the body “should” look like. Athletes in particular are expected to have bodies that fit to a T, or at least fit into a t (J).
Flat abs are particularly tied to how you eat- those late night purges on snickers bars and Coke will probably not help you out much. Now if you want to get abs like an athlete, diet is not enough. A strong core (abs and back) is essential for tennis- without it, you’re simply not up to par with your highest potential. So I’ll provide you with some not-so-fun-but-necessary-and-helpful core exercises to tone your muscles, sleeking them into the physique that is worthy of a magazine ad and aiding you in your tennis game (best of both worlds-really!).    
These exercises are not only ones you should be doing, but they do target your lower abs, which is where the dreaded belly bulge settles (more often on women then men- don’t get me started female/male comparisons, obviously I’m a little biased).
1.)  The bicycle

The bicycle keeps all of your body moving, but at the same time can isolate all of the muscles in the lower belly to continually pump your legs back and forth. Keep your fingers on your temples (otherwise you’ll start moving your neck and back, which defeats the whole purpose) and move your elbow to your opposite knee. The pace is up to you- you’ll feel the burn regardless, but a good starting point is 30 seconds on, 30 seconds off three times through.

2.)  The crabwalk
The crabwalk again keeps your body moving, and works on your balance as well as your abs. This exercise gets all of the abs working, including your upper abs that usually get toned quickly through crunches and a lot of other simple abs exercises. Facing your belly towards the sky, alternate touching your toes with your opposite hand while on all fours.  
3.)  No-idea-what-to-call-this AKA “Partner toe touches”
You know, explaining abs exercises through words is actually quite tough- glad that there are players around to torture with some extra abs routines and video at the same time. J This next one, although it does say partner, can be done without one. If you do have a partner, lie on the ground flat and grab your partner’s ankles. Your arms should be straight up. Pick up your legs to your partner without bending your knees- they should touch your feet to signal you to go down- NEVER touch the ground in this exercise. To make it more intense, have your partner throw your legs down instead of touching- this keeps your abs burning throughout the entire exercise (burn, baby, burn). Without a partner, grab hold of something that won’t fall on you (a railing, for example) and do the same thing.
4.)  Scissor kicks and up-downs
Very clever names, I know. Lie flat on your back, hook your arms underneath yourself, and pulse your legs up and down without touching the ground. Hence, up-downs. Keep going about 20 times, and then switch to scissor kicks- same position, crossing your legs over each other back and forth (sideways). About 20 times, then rest. And again.
When you’re doing abs, it’s extremely important to complete back exercises as well- the most dangerous thing (other than a good-looking front and a not-so-much backside) is to not strengthen your back as much as you strengthen your back; this causes a disbalance (yes, that’s a word in tennis lingo spell check!) that can end up in an injury.
5.)  Superman
It’s a bird, it’s a plane, it’s a bunch of junior tennis players training their backs! Lie flat on your stomach, stretch out your arms and legs, and lift your arms and legs simultaneously off the ground, and come back down. Point your toes when you do this, and lift up as high as you can. The more you wait up, the more your back works. About 40 will do.
6.)  Alternating superman
It’s a bird, it’s a plane, it’s a bunch of junior tennis players that are attempting to coordinate the alternating superman! Same thing as superman, but now you’re lifting your left arm and right leg at the same time, then alternating to the right arm and left leg. About 40 will do.
7.)  Weighted back lifts
Same position but your legs will lay flat the entire way through this exercise. Grab something with a little weight- if this is your first time doing this, do it with your racquet. Once you get better and stronger, you can add 5 or even 10 pound weights to this exercise. Place the weight behind your neck, holding onto it with your arms. Lift your upper body with the weight. Do about 15 of these, then rest and do it again.      
8.) I’ve saved the best for last- the plank. The plank is known to be the best ab exercise there is for abs and core strength.  Fold your hands together, lean on your elbows, and lift the rest of your body up. To make it harder, put your feet together—to start off, keep them apart. Start off holding on and off for thirty seconds, but if you can handle that just fine, do a minute on and off. You’ll feel the burn.
