GYM: Swiss Ball Hamstring Curl
Swiss Ball Hamstring Curl
Start in a supine position with your feet resting on a Swiss ball and arms by your sides, palms facing up. Raise your hips off of the floor. Bend at your knees while simultaneously raising your hips. Return to the starting position. Repeat for 10–16 repetitions.
The difficulty and benefits of this exercise can be increased by extending your arms toward the ceiling as this will require effective rotational stability.
At no point should you continue if your hamstrings feel as though they are cramping. Rest and continue once the cramping sensation has subsided.
