With the Thera-Band resistive exercise band system, treatment and exercise options are unlimited. Design exercise programs to address client's specific needs wherever they are - in a children's hospital, nursing home, sports medicine clinic, etc. A full spectrum of colors and resistance levels gives clients positive reinforcement as they progress from one color-coded level to the next. Thera-Band resistive exercise bands are as simple to use at home as in the clinic - so clients will continue to progress, even without one-on-one guidance from a therapist. 6" wide box.
