Getting fatter doesn't give you energy to build muscle, it inhibits your ability trk out better. Building lean muscle mass and bulk muscle mass is the key trking out more. You seriously need to learn how trkout, because if you think getting fat will help you, you need some serious help.

The guys you see that look fat that are in strongman competitions aren't fat, its bulked muscle, and power trained muscle.

Here is my suggestion to you, get some whey protein shake powder, take 1 shake 3 times daily, and work out with a combination of concentrated creatine with BCAAs, and you will build muscle and train better.
