Each strap is 5 feet long, durable, elastic, lightweight, and easy to carry. It can be used well in clinics, gyms, homes, or on the road. Research has shown that resistance bands have the same benefits in fitness and strength enhancement as weight training equipment. Give up free weight and try these portable resistance bands. These straps are very suitable for resistance training and rehabilitation, providing both positive and negative strength. You can wrap your hands in a few laps to achieve greater tension and a safer grip. Alternatively, they can be simply tied and used as circular straps, or they can be doubled to obtain greater resistance. The strap features vibrant color coding, and once you are ready for more challenging training, you can upgrade to the next color.
