Another development by the inventors of the exercise band and the progressive resistance system for combined exercises to enhance strength and coordination. Thera-Band® Loops are particularly suitable for lower extremity exercises. No wrapping or additional assists are required. They are optimally used for combined strength and coordination exercises. Loops are available in four resistance levels (yellow, red, green, and blue) and in three different loop sizes. The loops offer strengthening exercises in the well-known Thera-Band® color coding and provide options for toning specifically for the thigh area, while also serving sport-specific training.
