Toning Ball
Toning balls are a unique tool used to enhance many different exercise methods, including yoga, pilates and calisthenics. Made from soft vinyl, toning balls can be used instead of handheld dumbbells to add more resistance to any exercise, thereby helping to improve balance, coordination and flexibility. These balls weight from 1.1 to 5.5 pounds ( 5 to 2.5kg) and can be used to work the muscles of the arms and shoulder and also to improve upper-torso strength and flexibility. In yoga and pilates exercises, they're used to add resistance for muscle toning.
