The biceps femoris is a two-headed fusiform-shaped muscle. One head originates from the ischial tuberosity, the other from the back of the femur. Both heads combine forming a single tendon insertion on the head of the fibula bone at the lateral side of the knee. It can be palpated as a cord in this region.
The biceps femoris flexes the straight knee and outwardly rotates the lower leg (in the bent knee). Its rotary action accentuates twisting postures such as marichyasana III. Tightness in this muscle limits forward bends and certain standing poses, especially those involving internal rotation of the leg.
