Single Leg Swiss Ball Hamstring Curls

Lay on your back with one heel in the center of a swiss ball (aka exercise ball, physio-ball), and your other hip and knee at 90° angles. Place your hands on the ground near your hips to help stabilize your body so you don’t roll off the ball. Start by performing a single leg glute bridge to get the hips off of the floor. With your body in a straight line, curl the leg that is on the ball to bring your heel to your butt while maintaining elevated hips. Keep your glutes and abs flexed the entire time and don’t break positioning with the other leg.
