Hamstring Stability Exercise

The hamstring muscles are a group of three muscles. They're located along the back of the thigh, running from the hip to just below the knee.

If you're not flexible enough, exercise or movement can injure your hamstring muscles.

A Grade 3 hamstring muscle strain means the muscle tissue has torn away from tendon or bone.

There are a number of effective hamstring strength exercises you can do with a Swiss ball, including a single- and double-leg hamstring curl.

Because the hamstrings cross and act on the hip and knee joints, hamstring exercises can help strengthen and stabilize those areas as well.
