I've been working out for a while and I still can't seem to get my chest bigger. I know I'm getting stronger because I'm lifting the same weights and doing the same ammount of reps of the guys I work out with and they're huge. We work out our chest twice a week and I take one protein shake before I work out and eat pretty healthy. I try to run about two miles a day too. If I could get any suggestions on what I should do wether it be eating or a different style of lifting would be greatly appreciated. I'm also 6'4 and 185lbs if that helps.
