I’m 5’6, 117lb and want to make my body basically look like pic rel. I’m 24 and realise I can’t coast by on being thin forever as my metabolism will change; even slim middle aged people still have little pockets of fat, which is something I don’t want to have. So I figured the best way to delay the inevitable decline of my own body is by building muscle, which will burn fat and give me a degree of control over the fact my body is changing. So, to get back to the original point of this post, how do I go from being a skinny dyel to pic rel? How long will it take?
