To add to this guy, and I’ve been collecting so much of this for the hypertrophy manual…
So put all of this together - high level overview fellas…
- Make sure you’re using movements that fit your structure.
If you’re not built to squat, then choose a hack squat or leg press or some variation that fits your structure and mobility. If you have long femurs and shit ankle mobility then disregard the idiots on the net that tell you that you have to squat if you’re trying to grow your quads. Make sense?
- Make sure you executing properly with the movements that fit your structure.
This means that your setup, and how you’re performing those movements will dictate to where tension is going. If you’re doing shit reps, it’s a crap shoot to figure out what is getting the most tension. If you’re doing reps executed properly, then you should be making the target muscle work the hardest. Seems straight forwards.

Start loading at that point.

Count volume as only the number of reps you perform that actually go towards stimulating growth. This is what will eliminate you from doing junk volume.
4 reps in reserve is worth about 1 rep in terms of stimulating reps. So if you’re going to train with 4 reps in reserve then you’re going to have to do a metric butt ton of volume to get any growth from it. Meso cycles where there’s a lot of reps in reserve for weeks on end, builds systemic fatigue without ever truly activating the high threshold motor units. That’s why there’s so little growth.
The closer you get to failure, the more stimulating reps you’ll be performing. But all reps induce some level of fatigue. Both systemically and locally (muscular). The more systemic fatigue you have (nervous system) the fewer the reps you can perform, meaning you also don’t activate as many high threshold motor units. The more fatigued you are locally, when training a muscle group for example, then subsequent sets cause more activation of high threshold motor units. Again, that’s the SIZE principle at play here. The key here, is to minimize nervous system fatigue, while maximizing muscular fatigue with sets with a lot of growth stimulating reps. What’s the key there? For movements that are highly demanding, longer rest periods between sets. 3-4 minutes seems to be the ideal range.
- How to set your baseline for reps - If we know that 4 RIR is about 1 rep worth of growth, then that means a set of 5 that is a true 5RM has FIVE stimulating growth reps in it. Give or take. That should make sense to you.
Where does this leave us? It means that growth sets, on average, are probably going to have about 5 reps in them that go towards growth. A set of 10 taken to failure has…5 growth reps in it.
If you’re 5 RIR you did 0 reps worth of stimulation. If you’re 4 RIR it’s about 1 rep. If you’re 2 RIR it’s about 3 worth. This is likely why we see SIMILAR growth responses in 2 RIR to 0 RIR in most studies that are short term (10-12 weeks). Over a longer period of time I think the 0-1 RIR would bear out as far more beneficial. Which is what we did see in the Barbhalo study when the 5 and 10 set groups gained more mass and strength than the 15-20 set groups.
Once that stimulus has been caused, any extra work doesn’t go towards growth, but instead accumulates both more systemic and local fatigue. This would also make sense in that study as to why after 12 weeks (it was a 24 week study) you start to see a decline in the 15-20 set groups. They simply started accumulating more fatigue and couldn’t recover from it. Up to that point, at 12 weeks, the gains were fairly close.
This is why a model of weeks at a time where you’re leaving reps in the tank, then working up to failure over the course of weeks isn’t ideal to me. You’re training for weeks with no stimulating growth reps, accumulating fatigue during that time, then have to deload in order to recover.
Where a model where you’re not accumulating a ton of fatigue (local and systemic), performing a lot of growth reps, is the one where you’re going to be able to train at long periods at a time, making sustainable progress, without the need to deload and take breaks (which of course does nothing for growth).
Hope that helps.
