All Jack’s kids are great! They have smooth strokes and complete games. I’ve used the Broudy's tennis training tools for the past 20 years with both my varsity teams and my Nike camp. Everyone love his training devices because you can feel the fluid, natural tennis strokes!”

My brother Bob and I have known the fluid strokes and the 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 as to use this knowledge to play even better. His revolutionary system and various tennis training devices, can help every player feel the natural tennis strokes.

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 an effortless motion. I think 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.

I am a teaching pro from Argentina and when I discovered Jack’s system there was a before and after. He is a mentor for me. Thanks Jack for all of the chats that we’ve had and still have. His system is great – second to none! He is a great teaching pro but just as important to me he is a very good person.”

Jack is the first coach who patiently taught me how to use my hips properly and to play tennis non-linear. Using Jack’s concept of non-linear I can create power while staying balanced and dictate the play on my terms with fluid and powerful strokes. My tennis enjoyment has increased greatly and I’m ready for more as playing non-linear is so enjoyable and addictive. Thank you Jack!”

Jack can teach technique more effectively and faster than any coach I’ve ever seen. I once watched him teach a beginner to serve in less than 20 minutes. The student served with incredible pace and accuracy. When I watched it, I remember thinking “tennis coaches have been teaching the serve wrong this whole time!” If you have the chance to learn from Jack, I highly recommend it!”
