We used to only courses in the Full Community Membership, but then I added this annoying 25-year-old to our team...

He kept telling me "Jack, we can't just be course sellers! We need to give them an opportunity to take their learning to the NEXT LEVEL! We need to interact with them and make sure they GET IT!"

After some nagging, I realized he was right...

So, I listened to him and decided to make the Full Community Membership even better.

That's why we kickoff your membership with a Live Coaching Session to get a full assessment of your game. We'll get you started on the right track so you don't waste any time becoming a confident, fearless, beautiful, and effortless player.

Think we'd just abandon you? No sir... We want to make sure you continue focusing on the right parts of your game and develop the Nonlinear System perfect, which is why we do a monthly video analysis of your strokes.

Now, you may have questions each week and don't want to wait a month to have them answered. We hate waiting, too.

That's why every week we host a "Q&A Mastermind" where we go answer all your questions every week. You'll learn even more about the System and how to use it in your game through other people's questions.

We don't just help you understand the System like the back of your hand, We help you understand it like the back of BOTH of your hands (I couldn't think of a better analogy while writing this...).

I could go on and on about the other added benefits of the Full Community Access such as access to world-class Nonlinear coaches, exclusive live Q&A sessions with former grand slam winners, a growing library of videos that target the EXACT issue you're having and HOW to fix it, blah blah blah...

But if I haven't already convinced you, then that's TOTALLY fair.

In that case, I say this:
Join the free community, see if you like the stuff, TRY IT OUT on the court and see if it makes a difference in your game. If it doesn't, then Houston, we got a problem.

In that case, ask questions in the community or hop on a quick consult call with one of our Nonlinear expert team members.

When you're ready to transform into a confident, fearless, beautiful, and effortless player, we can't wait to help you ❤️

Whether you're a beginner 👶, a frustrated player on the verge of quitting 🤬, or a parent tired of the expensive coaching carousel 🤕...
‍
We've been the last and best coaches for 1000s of players with the Nonlinear System ❤️

My brother and I have known the fluid strokes and feeling of being "connected" in the game of tennis for much of our lives. It's great to know the science behind this feeling, so we can use this knowledge to play even better. Jack's revolutionary learning system and various devices, including the Swivels, can help every player feel and groove the natural strokes.

The Swivels are a great teaching tool to help learn proper coordination and kinetic chain of movement of the coil and uncoil. Learning to be athletic is key and the Swivels are that connection. If you want control and power Excalibur is the place to start. Not that easy to do but boy it teaches you to stay on the ball and compress through the hit which is key to power and control.

Brian Teacher

Jack Broudy is the first and only tennis coach I have ever worked with (and only online) who has been able to teach me how to master my strokes with a sort of effortless motion. It's actually thrilling to be able to hit a one-handed backhand without feeling that I am muscling and struggling to get the ball back with some pace. I love his lessons on the serve, since they are helping me learn to use core body mechanics to master a graceful stroke, rather than relying on whatever brute force I can muster up with my arm strength alone. His patented training device, the 8Board, helped me to feel and "own" this essential motion within minutes of stepping on it. I think the Jack's system will help non-athletes add a newfound gracefulness to their time on the court while advanced players will add power, precision and -- perhaps most importantly -- enjoyment to their game.

Helene Gittleman

I want to take a minute and let you know how much working with you improved my tennis game. Because of your help, I was able to raise my game to an entirely new level in a very short amount of time. You simplified my stroke, made it reliable and repeatable, and gave me an entirely new appreciation for how and why to play. I no longer fixate on how to hit the ball harder because you showed me how to generate power and accuracy with very little effort.

The more I came to understand your method, the more I enjoyed hitting the ball. This greatly improved my playing as my mindset changed from wanting to finish off points to wanting to hit solid shot after solid shot with the confidence that success would be the result. Perhaps the most impressive thing about your lessons is how much improvement I got in so little time with you. Because we're on opposite coasts, we were only on court together four times, but I had radical improvement anyway. Further, my wife and friend each had significant and lasting improvement in one lesson each. Can't wait until you’re back in NY and we can hit, or we're lucky enough to be in San Diego!

Just to let you know we’re working on the things you taught Nils and I. It’s doing wonders. He is improving so quickly now. It’s so easy to understand. One basic thought that can be applied to all strokes. He is really getting it. I don’t need to say much during practice anymore. We just talk about it before or after.

It seems like the Broudy System and the 8 Board help him in other sports as well. His rhythm and balance when he plays soccer and kendo are so much better. He is even getting stronger mentally, feeling really good about himself (but not in a cocky way.) Just really harmonious. Through all this he even gets his homework done in no time and he told me he enjoys school much more. Not that we didn’t enjoy it before but we have much more fun now.

So this was to say thank you again! I hope we can meet you again to work some more.

I learned to play tennis in the '70's and am a 5.5 player. I have struggled for years with the modern game and trying to hit good topspin off either wing. After 15 minutes of my first lesson with Jack Broudy on the 8 Board I was hitting topspin effortlessly and with power. I have been using the 8 Board and the Non-Linear Tennis System daily now and am more consistent and hit with more topspin, power and feel. I'm in love with tennis again. This is the best system for players at any level of the game and I truly believe that if you want to learn properly or improve your game, the Non-Linear Tennis System is the only way to go.

Jack Broudy is one of those rare people that takes a fresh look at old dogma and discovers a deeper truth. Jack has taken the tennis strokes and made sense of what is truly occurring in that whirl of activity, focusing on a few fundamentals of sound physical principals. As an Applied and Clinical Kinesologist I appreciate the simplicity and safety of his methods. Done properly it is hard for the tennis player to injure themselves and they truly use the core of the body that they have worked so hard to develop yet not known how apply in the strokes on the court. The results are graceful, repeatable and powerful tennis shots that are joy to watch a and hit! Thanks to Jack for his insights and dedication to tennis truth.

I always struggled with driving my forehand in match play. Until I learned about using a 45-degree angle with my feet on the semi-open stance, and about hitting the ball at a 45-degree angle in front of me. Yesterday I won a set 6-2 over someone I always lost to, because I visualized those 45-degree angles. It was the first time I ever consistently hit driving forehands in match play.
I was always told to hit the ball out in front on the forehand, but where out in front? The 45-degree rule gave me the specific answer I needed. Thank you Jack Broudy!

It amazes me after after several coaches no one taught the idea of leading with the hips. Just that alone gave me immediate improvement in my ground strokes.

I was leading with a unit turn and was so off balance and disconnected. Zero power from the ground and very very unstable. The ball could go anywhere. No confidence.
As you rightly say the tail was wagging the dog.
The figure 8 movement is a light bulb moment. I was looking for that for a long time. I started tennis when I was 8 and stopped when I was 16. I did the figure 8 unconsciously and had great ground strokes. I resumed tennis at 38 years of age and had no idea what happened to my forehand. I lost that deep secret. For the last 8 years. I’ve been getting all the the common tips yet still totally unstable and inconsistent in all my shots.
The figure 8 connected me to my true core and the ground driving my arms and shot.
Still got plenty of work to do also lining it up at the 45° and the sine wave.

So just come back - lost 4 & 4, no complaints with the result and very glad I stuck to trying to hit at the 45 and use my hips during each point.
What I noticed with the majority of my poor shots & unforced errors was that my swing pattern was very straight and the follow through got stuck in front. Whereas positive shots felt like I had a far more angular swing that stemmed from aligning my hips to the 45 during preparation.
Have a match tomorrow so hoping to see less 'straight swing' shots. Will focus on my hip direction (at the 45) in setting up each shot - I feel like this will help a lot in falling into the straight swing path that cost me a lot today. Glad I was able to park the ego and concentrate on the process...the loss hurts the pride but there is a bigger picture to consider!

Top coaches are big fans of the Nonlinear System 🤜🤛

All Jack’s kids are great! They have smooth strokes and complete games. I’ve use the Swivels for the past ten years with both my varsity teams and my Nike camps. Everyone loves it because you can really feel the fluid strokes!

Jack's System has already changed the sport of tennis forever...at least for me and hundreds of my students!
