Tennis Form Knee Trainer Aid

It’s most-repeated yelling in the coach’s dictionary on the court: “Bend your knees!”

The Knee Trainer is one of the most game-changing tools to come along in years. The Knee Trainer guides players to bend their knees automatically!

You would feel and hear a loud click exactly at the moment you bend, whether it is for general balance and movement, to load up before hitting a serve or groundstroke or to get down for all low balls.

Simply put, if the Knee Trainer clicks at the right moment or remains clicked as needed, the right technique is in place. Each unit includes detailed photo instructions.
