Box Burn

You can use a box as low as 6" if this is new to you, or you can have a box as high as 24" (or larger). You need a box that you can step up on as well as jump.

Jumps are done with both feet together. Try and land soft, meaning bend your knees and absorb some of the impact. You will be jumping on and off the box during the box jumps.

Step ups are done one leg at a time. It is a very controlled movement down and an explosive movement up. For a bigger challenge, don't allow more than just your heel to touch the ground on the down movement. This helps control it a little better.
