Theraband Exercise Balls are inflatable balls used to strengthen postural muscles to improve posture and help prevent back pain. They also increase range of motion, strength, and endurance as well as active stretching, active exercise and aerobics. Each exercise ball comes with two plugs and an adapter along with a full color exercise poster (Silver ball does NOT come with exercise poster).
Recommended Sizing Guidelines: In choosing the proper size of exercise ball, the ball should be fitted to each person's body proportions. For people who are especially long-legged or very heavy, the next larger size may be appropriate. Provided is a reference for seated position usage (hips and knees to be bent to 90 degrees when seated on ball).
