The Thera-Band Stretch Strap can be used with both static and contract-relax stretches, which is one of the most effective forms of stretching for improving range of motion (ROM) and flexibility. The numbered loops allow the therapist or trainer to provide clear, accurate instruction when setting goals and limitations. It supports classic static stretches, plus introduces more effective dynamic stretches. The Stretch Straps elastic design provides a highly effective contract-relax stretch while its slight give supports a more comfortable static stretch. The dual purpose of this strap enables complete replacement of static-only stretching straps. When used with our dynamic stretches, it helps improve flexibility and range of motion during rehabilitation.
