What are your goals?
Look good naked, brute strength, or functional training for sports?
If you are trying to build a physique (look good naked) then you want to hit every bodypart (calves, biceps triceps abs) directly. Most guys can't afford to wait until later to start working their calves, for example. Start working calves right away, unless you are lucky to have big calves naturally.
The simplest programs (to me) are Push/Pull/Legs, or Upper Body/Lower Body.
Just my opinion, I am not a professional trainer. This website is loaded with great routines written by professional trainers... read up and decide which ones seem simple to you.
