The reverse leg curl is a great exercise for the hamstrings and the glutes and calves also assist. While lying on your back on the floor, put your legs on a stability ball with your calves resting on the ball. For stability, spread your arms out with the palms towards the floor. Now lift your hips up towards the ceiling while simultaneously bending your knees and rolling the ball in towards your butt. You will go from having your calves making contact with the ball, to the bottoms of your shoes making contact. You should end with your shoulder blades touching the floor, your waist in a straight line, and your knees bent. Then return to the starting position and repeat for a killer set of hamstring exercises!
