Input:
This strap does what it was designed to do at a fair price.  I first used this strap while doing some physical therapy.  It made the stretching of my quads and ham strings  so much better. I am 55 years old and pulling on my legs with this strap is so much easier to do. I can lie in front of the TV and do my stretches by myself. My legs would get so stiff that they would pull my back out but not any more.
