Powerball Powerspin Evo...

● Powerful, efficient, effective – Powerspin is an upper body & arm exerciser which rapidly tones or builds muscle depending on the spin speed of the internal steel ball (no battery required).
● This simple device utilises isometric resistance to quickly engage a higher percentage of muscle fiber compared to regular isotonic free weight training.
● Small, light and portable, this fantastic fitness product is made in the United Kingdom and can be used as a home exerciser, in the office or as an efficient pre-sports warm up accessory.
● Powerspin develops 100% non-impact resistance, which may be used to rehabilitate elbow RSI, upper arm and shoulder impingement injuries and bursitis through enhanced blood flow and tendon strengthening.
● Produces visible, measurable results within a 30 day time frame for both male and female users, regardless of current fitness levels. Join the thousands of happy Powerspinners worldwide today to enjoy strong, toned arms in no time.
