This ball (10" diameter) is considered the beginner or basic ball, and it is the starting point for people who want to explore therapeutics. It has a softer edge and more give while still supporting your body weight.

This is the ball we recommend most for doing abdominal, chest and sideline work; it's also the recommended ball for lower back and pregnancy.

If you have osteoporosis, fibromyalgia or are rehabbing an injury, the gold ball is for you.

Note: This ball comes deflated and requires a pump.
