definitely, like the other guy said squats, deadlifts and also bench press are the 3 main excercises you should do. you also need to consume more calories than you burn but in a controlled way otherwise it can get very messy indeed. do not do it by eating loads of junk. low gl carbs like wholemeal bread, pasta and rice and potatoes and oats are what you want alot of as well as a lot of protein obviously. dont be ultra cautious about fat too you need some. also keeps your reps fairly low like 6-8 and the weight not too heavy and dont lift until fail cos this is better for size gains as opposed to strength increases. and try to keep the targeted muscles tense for longer by slower movements when lifting weights this increases gains.
