make sure your form is all good , try and train with someone thats been training for 3 years or so or even get a trainer that looks like he knows what hes talking about to teach you good form on the main building compounds
Squat , Bench , Dips , Dead Lifts , Chin ups , Leg Press , barbell curls
etc , do those with correct form as heavy as u can for 6 - 12 reps and see how u go
