You'll need a step bench. This sculpts your glutes, calves, thighs, hips, and core. Do 15 reps on each side.
The Running Man: Stand facing the bench or stairs. Take a giant step on to the stair with your right foot and hop up. Land on your right foot and then step back to the floor with your left foot. Do 15 of these explosive hops on the right foot using your arms to gain momentum. As you hop up, bring your left knee towards your chest. When you step down on to your left foot, keep your abs tight to help you balance, and hold your right leg out behind you. The running man targets your glutes, calves, thighs, hips, and core. After 15 reps, switch sides and do 15 hops out of your left foot. By holding one leg behind you for two counts on the down phase of this exercise, you'll work your abs and butt while improving your balance. To make this exercise easier, you could try stepping up without the hop and then hold the end position for two counts with your back foot on the floor for balance.
