My twins post (ByeMan) did well so I thought I'd give it a shot. I'm not as thin as him, but I have a good bit more muscle mass. Slowly getting back into the gym to get fit.

[BoC] M/27/5'10"/185 lbs (178 cm/84 kg). Been lifting a bulking for about a year and a half. Would like to add more muscle mass but am worried that I might have too much body fat already. NSFW-ish due to sexy tighty-whiteys.

35/M, really only one thing I like about my body. Wish I had more muscle mass, less gut.

25 (M), 6'6" 165 lbs. I'm one of these extremely tall and skinny, low muscle-mass, baby face guys! I feel self-conscious about my body for looking too weak or "unmanly."

38M, 5'10, 170lbs - haven't been lifting much but have been playing sports more often lately; worried I'm losing muscle mass, but I'm a lot happier changing it up from the boring gym routine--hence the smile.

28/M/5'7"(1,70m)/168lb(76kg) Last time I posted was over a year ago. Because of an injury I gained weight and lost muscle mass, which results in lower self esteem now. Nevertheless this is still me, my body, and I stand by it! (More pictures in comments)
