TheraBand 5-foot Resistance Bands are available in five levels:
Yellow - Thin Resistance
Red - Medium Resistance
Green - Heavy Resistance
Blue - Extra Heavy Resistance
Black - Special Heavy Resistance
Proper use of these systems for resistive exercise provides both positive and negative force on the muscles, improving strength, range of motion and cooperation of muscle groups. Color-coded progressive resistance gives at-a-glance documentation of progress from one level to the next.
