Later than planned, here is a video of me using the jump box I created here
The box has 3 platform heights - 16", 20" and 24", which makes it great to help with progressions, especially one legged jumps.
I'd like to point out that because of the way the box is constructed, it is heavier one side than the other, so requires a weight plate to be placed inside the frame to stop it rocking.
