Reddit reviews The Gold's Gym Encyclopedia of Bodybuilding (Gold's Gym Series)

Some people just don't put on mass like others. It's not a bad thing (I'm one of them) it kind of depends on the majority of the type of muscles you were born with; slow/fast twitch If you want to see gains you can listen to RadOwl (ignore the Men's Health crap), but I think he left out something very important; Negative reps, just not at first unless you're not a pussy, it affects the muscle and makes you sore like you've never experienced but they are very effective. I suggest this book, The Gold's Gym Encyclopedia of Bodybuilding, it's old but I still reference it, really simple and informative.
