Plyo Box

How to adjust

If it's a 3-sided adjustable box, choose the appropriate side/height; if it's a stacked set of fixed-height boxes, select the box with the right height.

Stand a comfortable distance from the box, swinging your arms and bending your knees to load.
Jump both feet onto the top of the box, landing softly with bent knees.
Stand fully upright on top before stepping (not jumping) back down.

Always step down off the box, never jump down, since landing from height onto the floor carries much higher impact risk than the jump up itself.
Stop the set the moment your legs feel heavy, your landings stop being soft, or you start reaching for the edge with your feet — that is when shins meet the box; drop to a lower box or switch to step-ups instead of forcing another rep.
Choose a height you can clear safely with room to spare; don't attempt your maximum height without a proper warm-up.
Make sure the box is stable and on non-slip flooring before jumping.
