The VerdictMODERATE CONVICTION

Where the bar sits changes how the squat feels, not how much muscle you build.

Next leg day, pick the bar position you can brace hardest and squat deepest with, then add a small amount of weight. That is the whole decision.

What the data actually shows: when researchers measured a true max lift, the forces on the muscles were nearly identical between the two styles.
The myth that won't die: that low bar "builds glutes" and high bar "builds quads" — that split comes from single-rep lab snapshots, not from anyone measuring muscle months later.
What to actually do about it: pick the version you can brace and squat deep on, and chase weight on the bar instead of switching styles.

Think of the bar like the strap of a heavy backpack. Wear it high and you stand tall, so your knees do more of the work. Slide it low and you tip forward to balance the load, so your hips take over. Either way you are carrying the same pack the same distance. You have changed your posture, not the size of the job.

The Practical Takeaway

Pick the position you can brace, hit depth on, and add weight to comfortably for your body. For most people that is the entire decision.
Train low bar if you compete in powerlifting. It is the lift you're tested on and it lets you load the heaviest.
Train high bar for weightlifting carryover, or if you want a more upright torso and a quad-focused feel.
If limited ankle movement stops you reaching depth on high bar, lift in a heel-elevated shoe or on a small plate.
Stop switching styles to chase "more muscle." Drive growth with volume, hard sets, and getting closer to failure over time.

Conviction

MODERATE

Confidence varies by claim. The posture and loading shift is well established. Whether one style is better for growth, strength, or safety has never been tested long-term.

"Net forces are similar at a matched max lift" — what would change my mind

This rests on a single 2024 study of 12 trained men (Larsen, PMID 38900172). A larger replication, or one using submaximal training loads instead of a 3-rep max, could reveal a meaningful split that this small max-effort sample missed.

"Neither position builds more muscle long-term" — what would change my mind

A randomized 8 to 12 week trial, 40+ trained lifters per arm, volume- and intensity-equated, measuring regional quad and glute/hamstring growth by MRI plus squat and transfer strength. A real between-group difference would turn "choose by goal and anatomy" into "choose by mechanism."
