Building muscle looks like a very easy task- until you actually start doing the exercises. If your underweight, or out of shape, it can be a challenge to lift weights. If your a skinny guy then it can be a great challenge. The truth about building muscle, however, is that anyone can do it. There are many tricks to doing it efficiently and it has much more to do with a synergy of actions than just lifting the weights. You have to eat right and exercise a certain way for your efforts to be effective and useful in building lean muscle.
