Use it under the lower back for support, between the knees, ankles, or hands to make workouts more challenging. Additionally, the ball will enhance your Pilates workout and help you develop strength, endurance, and concentration as well as promote relaxation and coordination. The balls are anti-slip offering excellent grip. Ball size is a matter of personal preference, but many people keep one each for variety and depending on what kind of exercise you're doing, you may have different sizes; 7" and 9". We also have soft balls that are perfect for Pilates studios and instructors to use since they are high quality and anti-burst, meaning if the ball were punctured, it wouldn't burst, but would slowly deflate, providing better safety for your clients.
