Input:
I was not a good stretcher until I discovered this. I used it at my gym one day and promptly came home and purchased one for myself so I would be better about stretching. This is a great product. It makes it so much easier to get good, deep stretches. It will also last a long time because it's thick and durable. I'm a huge fan.
