I had been looking for something to help me focus on my lower leg movement/balance/weight transfer on my ground strokes, and I've finally found the solution. Many tutorials and coaches out there tend to focus on arm movement, elbow, 'follow through', etc but all that doesn't help without proper lower body engagement.I'm happy with the purchase and I would recommend to other USTA players looking to improve their game.

I tried the device with great expectation. However, I am 6'-3" and most of my height is in my legs. The bungee chords were just not long enough to work without pulling the belt below my hips which I don't have. Just a word of caution for anyone taller than the 6'-1" limit in the large size.

Hard to stay in place and awkward to do workouts.
