Reverse Hamstring Stretch
To begin, lie down on your back and bend your knees so that your feet are flat on the mat. Make sure that your knees are aligned right above your ankles. From here, extend one leg to straight, directly above your hip. Interlace your fingers either behind your upper leg or lower leg, but not behind your knee. As you inhale, point your toes and press your leg into your hands. As you exhale, ground through your lower back and pull your leg into your chest. Use each exhale to pull your leg closer in towards your chest. For more of a challenge, extend your opposite leg out as straight as possible while keeping your stretching leg in full extension.
