Working out ???? bigger jaw?!

Working out ???? bigger jaw?

hey if u work out do get a bigger jaw....seems like all the people who workout quite a bit have bigger jaws? especially ufc fighters etc

thanks

Probably due to the increase in testosterone levels thanks to steroid use. Don't believe me? Check out female body builders, they have large square man-like jaws.

If you go to the gym and work out though no, you aren't going to get a big jaw.
