Hamstrings, like any other muscle, must be exercised and pushed in order to expand. You may target the back of the legs with the correct workouts (both with and without equipment) to enhance functional fitness, avoid injuries, and have more balanced and stronger legs overall.

Here are a handful of hamstring stretches to warm up before you begin exercising:
