Using your P2I 65cm Anti - Burst Yoga Ball is easy. First, use the included handpump to inflate the ball to the right size. For yoga and Pilates, you can sit on the ball to improve your balance, or use it for stretching exercises. To work on your abs, lie back on the ball and do sit - ups. When using it for buttocks and back workouts, try kneeling on the ball and performing some gentle backbends. Here are some things to keep in mind. Don't over - inflate the ball as it may cause it to burst. Also, avoid using the ball on rough or sharp surfaces to prevent punctures. To maintain your yoga ball, clean it with a mild soap and water solution regularly. After cleaning, dry it thoroughly before storing it in a cool, dry place. This will ensure your ball stays in good condition for a long time.
