I'm not a bodybuilder - a few push-ups every morning and I'll have enough strength for today. I'm not fat either - at 5'8" I weigh 150 pounds. On the advice of other reviewers who said this shirt is a size smaller, I went with the large one. Did because even that is quite tight. It can be worn but hope it won't shrink.If you are a fat guy with average height,don't worry.Cotton in the clothes,it's made in China.
