Hamstring Exercises

I watched a youtube video that showed an exercise for strengthening the back of the knee.

This was a pretty informative video, showing exactly what to do when doing the exercise. What is needed is a resistance band, which I have found is very useful for many different different physical therapy exercises. In this one, you loop it at the end and put your foot in it, while either someone holds the other end or you yourself tie it to to a strong surface. It's good that the exercise can be done on your own too, because it's helpful for people who live alone, or have no one around to assist them. The resistance band creates a tension that forces you to use the muscles in the back of the leg and knee. That is the point of the exercise. The video informs you that if there is pain there, to stop and get professional help about what is hurting and why. This was a helpful video for those trying to strengthen those muscles.
