I have a nagging question that's been bothering me for some time now. The notion of perfect (or at least, disciplined and structured) form is drilled into our heads fairly early in our lifting development. However, at literally every gym i've trained at, the few biggest guys, virtually without fail or exception, train in what could almost be considered a "sloppy" manner, speaking in terms of rep execution. Now, I don't mean to suggest that they bounce the bars off their chest, perform barbell curls that resemble some derivative of good mornings, or do side lateral raises that give them the aura of a drunken seagull trying to take flight, but there is unquestionably a good chunk of "body english" inherent in many of their working sets. What finally prompted me to ask this question was my viewing today of "Ronnnie Coleman - the Unbelievable" (well, the first ten minutes anyhow...more when i get home from work) in which his side lateral raises definitely do not look like the version you'd find in an exercise physiology book.
So, how about it AR - is a certain level of controlled chaos necessary to take your physique to the next level and really pound those muscles? Or, am i confusing an effect for a cause; ie, are these ripped and large guys so genetically gifted that they'd grow simply from talking about curls? Looking forward to some responses.
