I have the amp handles and it is one of the best purchases I have made. It connects with my Apple Watch- I use the CrossRope app on my phone - it records heart rate, rotations of the amp handle (jumps) and other things. I really love knowing how many jumps I made. The app beeps at each 100th jump.
Replied on I noticed when I squat that I am lean...

Aletta Armee thank you! I think I will stick with the butt taps and stretches for now.
