Gym Balls for Back Pain
Gym balls are a great way to keep you active, to get fit and to keep your spine and muscles strong. Gym Balls are used in sports, recreation, in classrooms and offices. By using a Gym Ball as a seat you create instability, which triggers core muscles to become active - it gives you a mini work out while you sit.
