We have covered volume a handful of times on the podcast — ETP#167 (Personalizing Your Training Volume), ETP#188 (Quality Volume), and most recently ETP#207 (The Training Volume Model). This one comes at it from a different angle: not "what's the right number of sets," but how that number can change over a training career as skill as a lifter improves.

The whole thing started with Aaron's quads. They used to be the body part he was almost ashamed of, and now they're on par with everything else. Except he only trains them once a week, six sets, and they're in shambles for five or six days afterward. That low a dose creating that much stimulus had Aaron questioning a lot of things, mainly: what actually makes a lagging body part lag? Is it genetics, or is it that you just haven't figured out how to contract the muscle well enough yet? Aaron's honest belief is leaning hard toward the second one.

So we get into the precision side of volume. Why a row isn't always a 1.0 stimulus, why your weak points might not need more sets so much as better execution, how strength curves explain why back and delts get buried under volume while quads light up off almost nothing, and how to actually manipulate all of this with rep ranges and resistance profiles. Plus some personal updates up top, including one of Aaron's that went unexpectedly viral.

Covered in this episode:

• Why volume needs can drop as your precision and skill improve, and the asterisk on "more volume is better until it isn't"
• Aaron's theory that lagging body parts lag because you haven't learned to contract them well — not because of genetics
• The Kyle Baxter pronation/foot-pressure cue that finally unlocked Aaron's quads
• Why quads hold post-workout stimulus for days when nothing else does (blood flow, lengthened overload, and the fact that we walk on our legs)
• Strength curve vs resistance curve, and why short-overloaded muscles like delts and back need more volume to reach the same inroads
• The leaning lateral raise trick — disadvantaging your own bad habit to force a better stimulus
• Using the 15/10/5 rep scheme to go short on the high-rep sets and lengthened on the low-rep sets
• Prioritization: deprioritize what's already good and pour the days into what you actually want to bring up
• Hamstrings/biceps vs quads/triceps, the cramp problem, and why some muscles just don't follow the same rules
