You can't tense all of your muscles at the same time though. Its a physical impossibility as there are some muscles that remain lose even if you tried to tense them all.

Try picking up a truck and lifting it over your head. Because you wouldn't be able to without the use of all your muscles working together. In fact it would just crush you if you tried. Using 100% of your muscle strength would make no difference, you would have to use all the muscles in your body to even get it above you.
