The original Stretch Out Strap™ from OPTP is made of professional strength woven nylon. The extremely durable strap is approximately 6’4” long and includes 10 individual loops for conveniently targeting muscles in the core, back, legs (quads, hamstrings, calves), arms, shoulders, and more. Unlike many imitation straps that are newer to the market, the Stretch Out Strap has been in production since 1993. As the first strap of its kind, it is the only one to be recommended by physical therapists and athletic trainers for over 20 years. Professionals have come to trust the unique design of this strap for its ability to provide safe, effective contract-relax stretches that improve flexibility, extend range of motion, enhance muscle recovery, and reduce risk of injury. Regardless of whether you’re an elite athlete, recovering from injury, or simply want to improve your flexibility and muscle function, the Stretch Out Strap provides simple, easy-to-perform stretching exercises. It’s an ideal, versatile tool for physical therapy, Pilates, yoga, and general fitness routines. The original Stretch Out Strap comes with a professionally developed exercise book that features detailed instructions and color photos demonstrating more than 30 stretches. Made in the U.S.A.
