differant folks, different strokes
so many people ask: "what is a good weekly program"
there is no correct answer to this
i'd suggest that you go to the gym, and try a couple exersizes, and, find which ones you want to improve upon (maybe you want to make a certain area of your body more aestheticaly pleasing, i don't know)
but, when you know what you want, you can ask:
"what is the best arm exersize" or leg exersize, etc.
which also happens to have no correct answer
to start: try and master body weight exersizes: these are simple enough, and will prepare you for more difficult weighted exersizes.
