Hit the gym to look like body builders or super saiyans from dragon ball z all say they do it for these reasons
*to get women (the kind of women who like guys with muscular bodies I can almost promise you have daddy issues)
*to stay healthy (I'm 125 pounds and 5'5 and I think I'm healthy and all I do is walk around my neighborhood for an hour or two smoking weed)
*to win in fights (these types of guys are clearly gangsters or thugs who want to be intimidating)
You can certainly make your body look outrageously big and muscular and won fist fights, but against a cheap pistol with a cheap bullet it's like David versus Goliath if you reas the Bible.
