(Updated July 2015) I wasn’t like some guys. Puberty didn’t automatically plumpen my pecs, and my weight never accidentally inched upwards on the scale. When I exercised, even when trying to build muscle, I’d need to watch out that my weight didn’t drop even lower. When I did gain weight, it was ephemeral. After every failed attempt I was sure that my skinny genes would keep me in my skinny jeans for the rest of my life… but it wasn’t genetics that were the problem, it was the fact that I wasn’t training properly for my body type or goals.
Following a mainstream approach to nutrition and fitness won’t get us the bodies we’re looking for, since most of them are designed to make us eat less and move more. They’re designed to help us lose weight or improve our fitness levels. That makes sense for most people, but obviously not for us.
There’s genuine muscle-buliding information out there though, especially when it comes to weightlifting. Building up bigger muscles is a relatively common hobby for men. That’s where the mainstream advice for skinny guys comes in: “Just lift heavy, man!” Yep. Lifting heavier would have helped… but it’s not quite that simple, and by leveraging science we can do a whole helluva lot better.
So let’s look into a few types of training that people commonly ask us about: bodyweight training (e.g. callisthenics, P90x), high intensity power training (e.g. Crossfit), strength training (e.g. powerlifting and 5x5s) and hypertrophy training (e.g. bodybuilding).
Then we’ll talk about what the evidence suggests is the best way to optimize muscle growth for us naturally skinny guys.
