Hamstring Curls with Swiss ball– Lying on back put shins up on Swiss ball and using legs roll it in towards you until your feet are on ball, lift your butt as you roll it in and bring the ball in close to your body, just under butt and then roll it back out to start position, bringing torso and butt back to the ground.
