You'll need a step bench. This targets your glutes, hips, hamstrings, chest, arms, and core. Do 10 reps on each leg.
-Leg Step Extension: Get on all fours with a step behind you, keeping your arms straight with your hands directly underneath your shoulders. Press your toes into the step. Tuck your left knee in towards your chest and then extend it behind you. You'll do 10 reps of this tuck-and-extend motion before switching legs. Squeeze your gluts as you extend your leg behind you. After you've done 10 reps, switch sides so your left leg stays on the step and your right leg is tucking and extending. Leg step extensions target your gluts, hips, hamstrings, chest, arms, and core. If you want to make this exercise easier, keep your back leg on the ground instead of elevated on the step, and do only 6 reps on each leg.
