Sit on leg press machine so that you are supporting your upper body on one side instead of on your back, with your bottom leg nestled on the floor to add stability. Place your other foot on the foot plate so that your toes are near the side edge of the plate. Push plate up, emphasizing pushing through your HEEL and squeezing your glute as the plate moves up. Return to start. Perform all repetitions on one leg, then switch to other side. This is more challenging than a single leg press that is performed when you are on your back, so use a lighter weight and concentrate on your form. As long as you are driving through your heel and getting that glute squeeze in, you will feel the burn even with a light weight.

Try stacking side single leg presses in a superset with weighted bench step ups or swing lunges to really blast the glutes and hams.
