I'm with dmunro on this one.
A lot of misinformation is out there. My old roommate thought he'd get absolutely ripped if he gained 15 pounds (he was 140) and if he got functional muscle. His planned routine? Push ups. Sit ups. Pull ups. Jump ropes. Side Straddles. Running.
He once refused to drink juice because it had more calories per oz than soda. I have no idea how he intended to gain weight or gain ripped on that kind of program. I'm just glad I didn't let him suck me into it.
The thing is, he did research. It was just bullshit research. He bought into everything Men's Health told him, and all that fitness marketing crap. Most people stray away from bodybuilding forums because they think they'll get "too big" (they vastly overestimate the effect of ten or fifteen pounds) or because they think it's all roiding. Instead they rely on the bullshit they see on TV, find in a magazine, or hear from their friends.
If a friend of mine wants to get jacked, I'm sure as hell going to make sure he gets properly educated before dipping into things. A huge chunk of men think that lifting a weight instantly makes you jacked and doing 5 kinds of arm curls in a sitting is a good idea. Another chunk think it's all about reps and not about weight at all. A third chunk thinks you have to mix up the workouts to confuse your muscles, otherwise they'll get really good at doing that one thing (they're too stupid to grasp that the improvement is the point, and we call it strength gain.)
