The number of total sets/reps per week is more or less the same - simply put, the volume per workout is controlled and much less than a regular 3x a week workout. This should make sense since you should always be doing as much as you can without overtraining.</div>
I actually go for the reverse. That is, I like to train as little as possible to get the maximum result. In other words, why do 3 sets if one will get you almost the same benefit. The extra sets burn more calories (energy) which requires more fuel and sleep and is harder on the CNS which can lead to overtraining or, perhaps more correctly put, stagnation. The preponderance of resistance training studies have shown very little difference in muscular strength, hypertrophy, power or endurance as a result of performing a greater number of sets. The jury is still out, however, on the efficacy of multiple exercises for the same body part. At best, they certainly have a diminishing return as the number of exercises increases. Whether they diminish slower than multiple sets has yet to be proven.</div>
You make some good points O&G.
But don't forget that one key to hypertrophy is total work. One set of 15 reps may be enough work for the muscle, but one set of 5 reps may not cause much hypertrophy at all, especially on an advanced trainee.
