Follow a sound program and eat your required calories for the weight you are trying to achieve. There are plenty of threads and articles floating around here as well as the internet in general. Biggest thing is to remember the BASIC FUNDAMENTAL aspects of strength training, it really is no more complicated than that.
REMEMBER THIS: If you are eating enough while using a program designed around the big complex lifts (squat, bench, deadlift, shoulder press), with some assistance work-- you will achieve your goal. Never think you are an exception to this rule, best of luck.
