I think the Bodybuilding Governor of California said it right in his encyclopedia. While hypertrophy is achieved in the 6 to 12 rep range a solid base of strength achieved through power-lifting is a necessary prerequisite. Several articles on here have alluded to the relation between poundage and muscle growth. In Bret Contreras article about shoulder and trap development, he measured a variety of exercises to quantify muscle fiber stimulation via EMG. If you notice the numbers posted on compound exercises with increasing weight, it is obvious that the more weight you can handle, the more fiber activation you elicit.
With this in mind, the magic 6 to 12 rep range for hypertrophy is only relevant if you are able to handle significant poundage in the first place. I see people my size every day at the gym following routines ripped right out of Flex magazine and making absolutely no progress. It is downright absurd to think that 4 sets of 12 dumbbell curls with 25 lbs in each hand would invoke any sort of hypertrophy. It is impossible to damage the muscle enough to see any real, lasting gains. It is much easier to quantify this phenomenon with simple mathematics. With 4 sets of 12 reps with 25 lb dumbbells, 2,400 pounds total weight is moved. In contrast, 10 sets of 4 with 45 lb dumbbells comes to a grand total of 3,600 pounds moved. It’s easy to see how less advanced bodybuilders could benefit from low rep training initially. Once the weights handled become too high, hypertrophy training comes into play, as compound lifts at a four rep or less max would be strenuous on the joints and difficult to recover from. The requirement of bodybuilding is frequency, so such high loads wouldn’t make sense. Four sets of 12 with 60 lb dumbells would total 5680 lbs, quite a bit of weight moved in short time considering a 30 second rest between sets. Arnold trained full body when he was building his base of strength prior to his bodybuilding heydey, and lifted like a power-lifter. I am a strong believer in the theory that people take what they want (in this case what seems easiest) from a training program and ignore the rest. Oh, and as a side note, machines are generally abhorred by the strength and function community but in a bodybuilding context you are able to handle more poundage than with free weights and doesn’t muscle respond to increased stress, whether or not the stabilizers are involved?
