The hamstring muscles run from the back of your thighs to your pelvis. Hamstring exercises can support your lower back and prevent lower back pain.

Studies show that exercise may help reduce symptoms of stress, anxiety and depression. Exercise releases powerful chemicals such as endorphins and serotonin, which improve mood and feelings of well-being. It can lower cortisol (also called the “stress hormone”) levels and support nerve cell growth in the hippocampus, a region of the brain that helps regulate mood.

Complex carbs will slowly release energy during and after a workout. Foods with simple sugars will break down quickly, which can result in fatigue. Look for foods such as multigrain bread, beans, bananas, berries and sweet potatoes.

The hamstring's tendons cross the knee joint and connect on each side of the tibia (shinbone). The hamstrings help bend the knees, a motion called knee flexion.

Hamstring muscles are the quads' opposing muscles. It's normal for the quads on the front of the leg to be stronger than the hamstrings. However, many people have a strength imbalance, so it's important to focus on the hamstrings in addition to the quads.
