I have a fast metabolism. I started out at 5'10", 150lbs. Here's a pic of me from a few years ago after a few years of training: I blurred out my face cuz you don't need to see my ugly mug. I pretty much each 3,000-5,000 calories per day and barely gain any weight. I sweat constantly and feel like shit most of the time when I eat 5000 or more. Sometimes I get food poisoning and I lose 10-15 pounds in a week. Here's a more recent pic. My arms suck. This is the biggest they've ever been: They don't want to get big, and when I'm not wearing a wife-beater I don't look like I've ever even seen the inside of a gym. My arms will get strong; I can do full range one-arm chins when I train for it, but they don't wanna grow. Here's another pic: My only bodypart that grows easily are my lats. I don't do much back work at all, and somehow I still have relatively big lats and can do a lot of chinups/pullups. This pic is from after a powerlifting meet a while ago after I had just done 18 chinups, so I had a pump. I think I posted that vid here a while ago. Here's a recent leg shot. I'm not wearing weird ass underwear, I just pulled the legs of my boxers up: My legs are weak as all hell. After 5 years of training I could barely squat 315 @ 170lbs (when I squated I could barely squat 95lbs). If I take a week or two off from doing squats, I lose just about all my strength (as opposed to my lats, which I never have to train and I can still do chinups all day... crazy genetics). But at least when I squat I go down all the way: Vid - 315 @ 170lbs <-- click Is my form ok? Ignore the second half of the video. My camera man forgot to stop recording, I think.
