Episode 20 with Kassem Hanson - Is The Squat the Best Exercise For Quad Hypertrophy?

Or is the squat a decent exercise to develop the quads and glutes until it’s not?What is the muscular limiter for the barbell squat? Is it even a muscle?Episode 20 Notes “From these data, it is unclear if strengthening a single muscle group (e.g., knee extensors) would increase squat strength, as the strength of one muscle group does not appear to relate more strongly to squat strength than another…Net joint moments observed during the squat do not approach 100% of what each joint can produce in isolation…The relationship between individual joint strength and multi-joint strength may be highly nonlinear and paradoxical, owing to the increased degrees of freedom of multi-joint movements…Humans may be less than the sum of their parts when it comes to multijoint force production”Vigotsky et al. 2018It seems like counter to what people think that by putting the barbell further away from the center of mass you are probably allowing for a more upright torso…until you aren’t. Meaning we actually see more and more erector spinae activity as you move the bar further out so the likely limiter here is just your ability to hold the position under increased fatigue and loading. https://journals.lww.com/nsca-jscr/Fu... and we probably can’t trust our eyes here for telling when people lose lumbar “neutrality” anyways.https://www.ncbi.nlm.nih.gov/pubmed/2...The glutes aren’t really working much in the bottom of the squat (the hardest part of the lift) in their lengthened position…it looks like that is primarily adductor magnus. So the glutes really wouldn’t be the limiter to extend the hip ever in the squat and wouldn’t even be used much until after 90 degrees and their force output above 90 is likely way more than anything we could put on the bar anyways. https://www.ncbi.nlm.nih.gov/pubmed/3...https://www.ncbi.nlm.nih.gov/pmc/arti...https://www.ncbi.nlm.nih.gov/pmc/arti...https://www.researchgate.net/publicat...https://www.ncbi.nlm.nih.gov/pubmed/2...Could the muscular limiter in a barbell squat variant ever really be the quads?We generally see people tip forward as they start to fatigue out later in
