How to gain weight.................

Now the concern some people have about how to gain weight, is how to do it without putting on extra fat. Let me tell you how, 

YOU CAN'T! Unless you are using steroids, it is basically impossible to gain weight without putting on a little bit of extra fat. 

But hey, you want to see some weight gain right? Well then who cares about the little bit of extra fat you might put on while gaining. 

You will be able to burn that off later on, right now gaining is your main concern, so that is all you need to worry about.
