The Bicep femoris is the most important of the three hamstrings because of its role in biomechanics (how you move). It directly connects downward through the lateral calf to the heal and upward through the pelvis leading up to the head and out to the arm.
So if it is not strong enough or too tight you will not move well, have pain, and exert more energy than is needed just to move around.
Parameters MFS:
- Do 3 X 30 sec each side
- The goal of pulling the knee down is to eventually get the heal off the ground.
