Blue Balance Ball Trainer

The Balance Ball Trainer helps you strengthen and coordinate several major muscle groups, including your core muscles, back muscles, legs, and abs. Adding an element of instability forces your body to use more muscles from your core, so you no longer must rely on crunches or sit-ups for your abs workout. The resistance tubes attach directly to the base for other bodyweight resistance exercises, adding an extra dimension to your standard workout. Perfect for physical therapy and recovery exercises.
