Exercise balls provide a full-body workout that strengthens core muscles and improves balance and symmetry. Originally used in physical therapy, they have become a popular fitness equipment item. While versatile and portable, exercise balls can pose safety risks due to their inherent instability. Some tips for safe exercise ball use include warming up first, choosing the proper ball size, maintaining control of movements, keeping traction, wearing comfortable clothing, and exercising in a spacious clear area. Proper form, posture, breathing, and fun should be maintained during workouts.
