Thera-Band® Soft Weights are hand-held, ball-shaped isotonic weights, a soft alternative to traditional dumbbells. Thera-Band Soft Weights are perfect for strength training and rehabilitation exercises. Each ball has a diameter of 4.5" regardless of its weight, allowing for a consistent and functional grip. Soft Weights follow the Thera-Band system of progressive exercise and are available in six color-coded weights, ranging from tan (0.5 kg/1.1 lbs), to black (3 kg/6.6 lbs), increasing in 1/2kg/1.1 lb. increments. Soft Weights allow users to increase weight in resistive training and rehabilitation programs without changing grip or technique, which is fundamental to the principles of progressive exercise. In addition to traditional strengthening exercises for the upper and lower body, the Soft Weights can be used for many other applications. Their soft texture allows for functional grip or exercises for individual fingers which aid in hand and wrist rehabilitation. The Soft Weight can also be used for plyometric exercises for the upper extremity with a rebounder or mini-trampoline. Balance training or stabilization exercises can also be performed using the Soft Weight for patients with lower extremity or lower back injuries
