Power Jumper Is The Best Resistance Product On The Market
I've used the power jumper when I do squats, lunges, split jumps, dynamic step ups, chair jumps, and box jumps. It works extremely well and is the best resistance product on the market and there may never be another like it.
VerticalJumping.com Response: Hi RJ, I couldn't agree more. It is very versatile and as you have discovered, it does get results. Glad to hear you are enjoying it.
