I guess ill help u out kid.
having work in a all womens gym and even in an all medical student comminity, i frequently been asked to train and repect the wish of avoiding hypertrophy. well a couple of things, 1st if u do not want to get big, your mind will not even allow your body to SUPERSIZE itself. just like milos sarcev said " this happens by design, not by accident". For those type of bodies u have to analyze your bone structure to look like these guys, Pretty small jointed at the wrist elbows, knees, kinda broad shouldered (note; said kinda) then check how much body fat u carry, do u have visible abs. then check your diet. eat clean enough to get lean.
As far as the training, just train hard,(for you) full body style might be a good method. 3-4x weekly. (its very hard to get big on this type of program anyways) and also get into some conditioning drills and cardio. or like Jaxun said; do some crossfit.
well hope this helps.
