Here is all kind of core and edurance training in pushup position.
IF you can do this for four minutes you the man. I would guess most people would not be able to do a minute.

I tried all of them. 4 minutes, yeah right. Forget about core strength, you nee strong shoulders and whole lot of cardio to do this. Very good conditioning. Much more difficult that it looked at first.
