This is a 50-yard roll of the Green (Medium) Band. Exercise bands are effective when used alone or with handles and anchors. Made with Tear-Stop technology for reduced puncture and "snap" breakage. They are a well-known staple of most physical therapy offices, clinics and gyms because they are durable, powderless and textured for easy gripping. The 50-yard rolls have a core that fits most dispenser racks. The width is uniform across the bands at 5" wide. Bands are available in 8 levels of resistance for progressive exercise. Levels range in order of strength from least to greatest resistance: tan, yellow, red, green, blue, black, silver, gold.
