These 0.5kg Toning Balls are ideal for strengthening, mobilisation, plyometrics and balance training. The 10cm diameter size fits perfectly in the hand and the ripple grip design is comfortable and secure. The Toning Balls provide a smoother movement to standard dumbells and the soft shell outer is safer when dropped. Sold in a pair, these Toning Balls are the ideal accessory to add a little weight to your next mat, movement, rehab or pilates class.
