Prison Workout - The Push Ups

To keep things simple, I am only picking three pushup exercises. Below is THE PUSHUP.  Other than the other two variations specifically listed in this post, your hand or feet positioning does not matter. 

This is the DIVE BOMBER.  This version targets a few extra muscles, and requires some extra isometric balance and stabilizing effort.

Lastly, this is the DIAMOND PUSHUP.  The close grip concentrates the work on the triceps. A wide feet stance helps with balance. Be sure to keep a solid planking position. It is easiest to sag the hips and tent the butt with this hand position.
