Stability Ball Hamstring Curl (One Leg w/ Thrust)
- Stability Ball
1) Lay flat on the floor and rest your left leg on the top on the ball. Lift your right leg up so its facing the ceiling. Place your hands either side.
2) Lift your hips up slightly and engage the core.
1) Curl your leg in and bring the ball closer towards your body and thrust up. The endpoint should be your lower back raised from the floor with your heel still on the ball. Your knees should be bent.
2) Pause for a second - you should be crunching the abs at this point. Slowly extend your leg and push the ball away from you to the starting position.
