How To Build An Easy 3-in-1 CrossFit Jump Box With A Single Sheet Of Plywood Video

Build a plyometric, Crossfit-style jump box with nothing more than one sheet of plywood and some grabber screws. Three jumping heights by simply rotating the box: 20 in, 24 in, and 30 in.

You'll need:
- basic carpentry skills
- goggles
- 1 4x8 sheet of 3/4 in plywood (any grade should do)
- lots of screws. I used these screws: http://amzn.to/1TYD7fa
- drill or impact driver with bit to match screws
- less than an hour

I found a great diagram on how to cut a single sheet of plywood into the boards needed to build a jump box at http://www.endofthreefitness.com. I decided to build one for our home gym and make a video to show how easy the process is. Tested it out and it feels bomber. I am happy with the amount of range between the lowest and highest height.
