Thera Band - Tubing With Hard Pvc Handles Thera Band Tubing is an alternative to conventional free weights or elastic bands. Athletic Trainers prefer it because the color resistance levels are the same as Thera Band Exercise Bands used in physical therapy. It is also used in occupational therapy, orthopedics, pediatrics, sports medicine, home health care, geriatrics, hand therapy, and Chiropractic. The PVC Handles on these Resistance Tubes are perfect for people who prefer a hard handle as opposed to a softer one.
