IGNIO Fitness Ball 65cm This is a new, unused item, but the corner of the box has been chewed by a dog. The product itself is fine. It was stored at home without being used after purchase. This size is suitable for people between 165cm and 180cm tall. An air pump is included, so it can be used immediately. Exercises that focus on core strength and balance while engaging your abs are effective for your inner muscles. Simply sitting on it as a chair while watching TV or studying can be a form of exercise. It will be packed and shipped in its original box. This 65cm fitness ball is perfect for balance, strength training, and stretching.
