Using a plyo box is actually really simple. Just place the box on the ground, stand facing the box, and jump onto it—planting both of your feet on the box at the same time. To make sure you stick the landing, you’ll want to start with your feet planted firmly under your hips—and with your toes about 6 inches away from the box. When you land, make sure most of your weight is in the balls of your feet. And double-check that your feet are still about hip-width apart once you’re on top of the box.  Plyo boxes can be used for other exercises, too, like step-ups, Bulgarian split squats, front-foot-elevated reverse lunges, and more.
