NSD Powerball 280hz Cord Start Models Strengthening and Rehabilitation

16KG IN RESISTANCE - At just the size of a tennis ball, Powerball can spin at up to 18,000rpm (rotations per minute) and output a massive 16kg in resistance. Give Powerball as a spin - we guarantee you’ve never felt anything like it, BUILD GRIP & ARM STRENGTH - As you spin Powerball it generates resistance - the faster you spin, the stronger the resistance will be. Harness the immense power of Powerball at fast speeds to build solid upper arm muscles, a stronger wrist and the ultimate grip, GREAT FOR REHABILITATION - At low speeds, Powerball is highly effective in injury rehab and pain relief. Weather it’s a wrist, hand, finger or forearm injury; or stiffness and discomfort in these joints - then Powerball is for you. Used by millions worldwide for injury prevention & recovery (carpal tunnel, tendonitis, breaks, sprains, etc), 100% ISOMETRIC EXERCISE - Powerball generates isometric resistance as you spin it. Isometric resistance engages a much higher percentage of muscle fibres than standard isotonic training (e.g. free weights) does. It is also non-impact, making it a form of strengthening that places ZERO strain on your muscles as you exercise, ENHANCED SPORT & MUSICAL ABILITY - An effective exercise tool that will dramatically improve grip strength and finger dexterity, Powerball is a must-have product for all serious athletes (golf, tennis, climbing, boxing, etc.) and musicians (guitar, drums, piano).
