If you want to feel the fire in your abductors, quads, calves and glutes, using step up leg exercises will definitely heat things up. Stand in front of either a park bench or a step with your feet positioned hip-distance apart. Step up with your right foot, push yourself up and place your left foot on the surface next to your right one. Step down with your right foot first, and then your left foot. Repeat the movements, stepping up with alternating legs each time.
