Tips for a newbie

So this time last year I was near 20 stone, I'm currently like 202 pounds, I've done the whole gym thing before when I was like 16 but over never really done it properly (I'm 22 now). I'm looking to build muscle as I know I have the frame and natural physique from my fathers genetics, I was wondering if any of you out there have any good ideas for routines/sets of exercises for someone who's looking to start some bodybuilding or just getting bulkier so I can fill out my loose skin a little more.
