I purchased this yoga strap by #Tommie as part of my rehab. I had my 2nd rotator cuff surgery back in August and I'm still doing physical therapy. One of the things they have me do now in physical therapy is to use the yoga strap. I put one loop at the top in my left hand and reach behind my back to the biggest loop with my right hand. I then pull up till I feel a stretch and hold it for 30 seconds. I repeat this 3 times. I purchased this one to use at home as well as at the physical therapy center due to the fact that with Covid I can know for certain that the equipment I'm using is clean. This strap is made extremely well and at $19.99 very affordable.
