    With your partner holding your leg in place, attempt to flex the knee, contracting the hamstrings for 10-20 seconds.

    Then relax your leg, allowing your partner to gently push the leg towards your head. Be sure to inform your helper when the stretch is adequate to prevent injury or overstretching. Switch sides once complete.
