The Sport Loop Resistance Band is great for working your way up to a full un-assisted pullup. Pull-ups are one of the best ways to build your back and biceps. The bands are best used wrapped around a pull-up bar and then around your knees to help provide assistance. Tone your arms, shoulders, legs or knees. Perfect for yoga training, physical therapy or to help strengthen torn ligaments or muscles. With resistance band training every part of the exercise has resistance. This Band offers a different level of resistance, both for pull up training, and for adding resistances to bench press, squats and Olympic lifts.
