I posted this in another thread but I'll post it here seeing as it's about it. There is a difference between what hypertrophy is and what a hypertrophy routine is. 8-10 reps does not make a routine a hypertrophy routine, the routine as a whole makes it a hypertrophy routine. HST is a hypertrophy routine,
Hypertrophy Specific Training, you hear that? It's training
specifically for hypertrophy, aka mass, rather than strength (which will come with it).
The following are the principles that determine whether a routine is a HST routine. A routine specifically designed to induce hypertrophy better than another.
Hypertrophy-Specific Training (HST) is a method of strength training intended to induce muscle growth, or
hypertrophy, in its practitioners. The method was popularized following an October 2000
ThinkMuscle newsletter article by fitness writer Bryan Hay****, which discussed methods he and his clients had been using for several years.
Hay**** says that the training method arose out of "physiological principles of hypertrophy discovered in the laboratory," and that these principles were then organized into a weight training method meant to induce hypertrophy.[1]
Strategic Deconditioning: To continue hypertrophy, the load must be temporarily eliminated, to allow the muscle to "Decondition" and allow hypertrophic response to training once again.
This process happens after the end of a 6-8 week "cycle" and can last from 9–14 days preceding a new "cycle".
Progressively Adjusting reps to accommodate Progressive Load:
HST suggests that you change how many exercise repetitions you perform every 2 weeks, to accommodate the ever increasing load. Most "HST" programs start with a 15 rep, 2 week "semi-cycle" that is performed over six workouts with the sixth workout being at the exercisers maximum weight.
The next semi-cycle, reps are reduced to 10, then 5, finally ending with a repeat of the 5 rep cycle, or eccentric repetitions. Each semi-cycle adds to equal one full 8 week cycle.
These are the rules of a hypertrophy routine, not 8 reps of isolations - but all of these rules together.
Hypertrophy = muscle growth, which is achieved by a calorific surplus.
Hypertrophy routine = these rules and principles brought together to create a routine targeted at gaining mass over strength.
And just to add to your point above MVP, hypertrophy routines are typically supposed to have no more than 2 sets per exercise.
