HOW: Begin with your shoulders resting on an elevated surface and another elevated surface at your feet. Place your heels up on the elevated surface with a slight bend in the knees. Push your hips up into an extended position to target your hamstring muscle group. Hold for the prescribed amount of time before returning to the starting position.
FEEL: You should feel your hamstring muscles behind your thighs working as you hold your body in the elevated position.
COMPENSATION: Avoid lifting your hips so high that you are compensating by arching through the back. Keep a neutral pelvic position as you raise your hips up.
