Alternative to dumbbells - Flexible use during training - Resistance training anywhere, anytime - Go-Band™ provides every clinic, hospital, and patient with the space-saving and cost-saving bands for rehabilitation and home exercise. The darker the color, the more resistive the band. 50 yard bands are great for high-traffic clinics that want to purchase in bulk, and 6 yard rolls are more convenient for a patient to use at home. Each roll is 5” in width.
