The hamstring plays a pivotal role in walking, jumping, running, cycling or swimming. The hamstrings are the powerhouse of your legs. Hamstrings allow you to bend your knees, straighten your leg and control movement from the hip. A hamstring injury can cause a big disruption in your fitness or training regimen, leaving you on the couch for weeks if not treated right.
