Eccentric Single Leg Hamstring Curl – Swissball, Two to One
HOW: Start by lying on your back with a swissball underneath your feet. Bend your knees with your feet flat on top of the ball. Push down into the ball lifting your hips up. While keeping your hips up, take one leg off of the ball and let the other leg slowly straighten while still pressing down into the ball.
FEEL: You should feel your hamstring and core muscles working.
COMPENSATION: Don’t let your hips drop down as you extend your leg out.
