What does your current routine look like? How many sets, reps are you doing per bodypart? If you are overtraining you are probably not eating enough and are possibly losing muscle or not gaining because of this? The key to growing is progressive overload and eating more then you are use to. There is no secret workout. Often times bodybuilders use the same workout to bulk as they use to cut. As I mentioned before diet plays a huge role in the way you look.
