To add, most bodybuilders WHO DO NOT use gallons of test/gh/slin and do not train for progressive strength increases in big lifts are small, under 200lbs, and if you saw them in a t shirt you would never know they worked out. But, it is only a matter of time before they discover the *secret* exercise or program or angle to put the incline bench at for Smith machine presses that will take them to hugeness, right?
FLEX, MuscleMag, Weider Principles, the supplement industry, and actually modern 'bodybuilding' as a whole is involved in a cover-up at the expense of uninformed people's bank accounts.....People buy mags, they read ads for supplements, when supplements sell, the supplement companies get rich and advertise more in mags, making the mags rich....for people to buy mags, you can't just keep printing 'squat, pull, press, eat, repeat'....most people don't want hard, but simple.....they want easy, but complicated. Nobody who is natural or even moderately juiced is getting huge on a 'routine' that isn't focused on bringing up big lifts, just walk into any gym in America and look at the average size and strength of the members, they aren't small because they don't juice (a lot of 'em actually do and are still pussies), they aren't small because they haven't discovered the magic routine or supplement, they're squids because they do not know how to train progressively over time.....the cover-up if anybody hasn't guessed is of course the fact that the routines in the mags and pumping and blasting won't work unless you're a genetic freak who is also completely reliant on drugs and ancillaries, then the rest as they say is 99.9% diet (another joke, but thats another topic).
Anybody who really thinks that in a natural trainee, bodybuilding and strength training are vastly different, doesn't know a thing.
Training compound lifts progressively always slaps muscle on people, natural or not, so long as they aren't starving themselves. If you want to train '1 bodypart a week', then fine, just make sure the squat, deadlift, bench, overhead, row etc go up. The reason strength training uses frequency is because it fosters faster progress, however the once a week split can be effective if it isn't cluttered with buttheaded iso exercises and centered around 'getting pumped and sore'. Seriously, anybody doing a ton of iso crap wouldn't even notice if they dropped it, so long as they kept getting better on th stuff that counts.
