Proper use of exercise bands help provide positive and negative force on the muscles, improves strength, and range of motion. Color-coded progressive resistance gives at-a-glance documentation of progress from one level to the next. With Thera-Band resistive exercise systems, measuring progress and achieving goals for fitness or therapy is easier than ever before. Different resistance levels are determined by thickness of the band or the tubing. We designed the Thera-Band progressive resistance system with color-coded levels increasing in difficulty from tan to gold. This comprehensive system provides positive reinforcement and feedback for gauging results.
