🎯 The 90-100° Depth Hack — The Squat Sweet Spot Science Actually Confirms

Everyone argues about squat depth, but the research settles it clearly: quadriceps hypertrophy is maximized once you reach roughly 90-100° of knee flexion — right around parallel or just past it — and going shallower than that genuinely leaves gains on the table. One controlled study found the group training with deeper knee flexion (up to 100°) built significantly more vastus lateralis muscle than the group stopping at just 50°, confirming the "squat low" message in the image is backed by real data, not just gym folklore.

Push even deeper than 100°, though, and the extra benefit shifts away from your quads — full-depth squats past 120° primarily drive extra growth in your glutes and adductors instead, while quad growth plateaus. The hack? Hit parallel to slightly below it every rep to fully maximize quad hypertrophy, and only go deeper if your goal is building glutes and adductors alongside your legs — you don't need to smash your hips to your ankles to get maximum quad size. Squatting shallower than parallel does let you load more weight, but the strength gain from that extra load doesn't translate into more quad muscle — it's a trade-off, not a shortcut.

Drive up explosively out of the bottom like the image shows, and keep that depth consistent every single set — that's genuinely the difference between average legs and legs that actually turn heads 💪 For the man who built the single most legendary set of quads in bodybuilding history through insane depth and volume, watch TOM PLATZ - THE GOLDEN EAGLE ENGLAND TOUR - SEMINAR - WORKOUT - POSING , available now at Prime Cuts Bodybuilding.
