Single Leg Exercise Ball Glute Bridge

Lie with your back flat on the floor and both feet on a stability ball, legs bent at a 90 degree angle. Rest your arms straight on the ground by your sides. Lift one foot off the ball and extend it out straight. Squeeze your glutes to thrust your hips off the ground. Brace your core so that your torso forms a straight line from head to knees. Pause, then slowly lower your hips back to the ground. Perform all reps, then repeat on the opposite leg.
