Hamstring Flexibility

Lifting the hips upward after placing the arm on the opposite side of the front foot creates a hamstring stretch in the front leg. The drill combines light hamstring activation with controlled breathing performed while lying on the back. Digging the heels into the elevated surface causes the hamstring muscles to engage. The hamstring stretch phase follows the upper-back rotation step within the same continuous movement sequence. The drill is designed to improve hamstring function and increase range of motion. Hamstring flexibility is listed as one of the primary areas targeted by the World's Greatest Stretch.
