Bending your legs properly is easier said than done! You may think you are bending deep but if you look in the mirror or film yourself you are often surprised at how little you actually bend your knees. To learn what it should feel like to bend deep enough, you need to get the right feeling. So it's all about practice!

With the innovative Tac-Tic Knee Trainer, this can be effectively learned by giving the tennis/padel player immediate feedback during active practice. If you bend your knees enough, it clicks loudly and you know that you have succeeded; that you have used the right technique. Learning to bend deep is important whether you are practicing for general balance and movement, to recharge before hitting a serve, smash or groundstroke, or to play low balls. Perfect for tennis and padel players but also for a variety of sports such as golf, baseball, football and basketball.

Complement your training with the Wrist Trainer to not grip your rack too tightly when serving, smashing and groundstrokes. Effectively learn how to instead allow your wrist to twist when hitting the ball.

I've practiced tennis all my life and know how important it is to use technique to make it stick. Just had the opportunity to try TopspinPro and wish I had discovered it sooner! Now both me and my tennis playing kids can practice technique and fundamentals at home, really fun and easy! Highly recommended regardless of ambition level.

I serve 60 times a day with ServeMaster and have noticed an improvement in just a few weeks. Yesterday I played a match and felt so confident when I served.
