they've chosen extremely odd places to film them. The one place looks like the back of a lebanese restaurant.

I think most people try them, fail, and quit. The thing to remember, and I said this in another thread, don't do any weight training exercise that you couldn't do plyometrically in the sense that yuo could thrust the weight at least 2-3" away from your hands, feet, whatever. so when doing a plyo pushup, if you can't go all the way down and thrust yourself into the air, start by dipping only a few inches. Then get deeper as you get stronger. Also position your hands in various places, coming as close to mimicing the motion and path of a punch as possible.
