Used by physical therapists for years, we can now make these Thera-Band balls available to you at home. Use your ball in a variety of ways: lie over it to stretch and lengthen a tense spine. Lean back on it to tone those tummy muscles. Support your feet on it to exercise legs. Or you can just bounce around and have fun while giving your cardiovascular system a workout.

Colourful and Fun
It's said that 10 exercises with a ball are equivalent to 30 without one. That's because when using a ball you're working groups of muscles together, all at the same time. It's a particularly effective method for backs, as you're supported while you exercise. The balls are made of wipe-clean vinyl that's tough enough to withstand heavy weights, and they are anti-burst for your safety. A comprehensive exercise programme is included.
