This move is like a walking vertical lunge so it targets the entire leg, with the focus on the quads, glutes, and upper fibers of your hamstrings. Concentrating on the heel pressing into the step will ensure that the back of the leg works as much as the front.
- Find a step or a bench that, when you place your foot squarely on it, your knee is at a 90-degree angle or larger.
- Place your right foot on the step. Press through the heel as you straighten your right leg to stand on the box while bringing your left leg forward like you're marching.
- To return to the starting position, step down with your left foot, then the right, until ending with both feet on the ground.
- Complete 20 reps on each leg.
