  • Outer quad

    Hit

    Vastus lateralis - outer sweep.

  • Inner quad (teardrop)

    Hit

    Vastus medialis - pops with full depth.

How To Get A Huge Squat With Perfect Technique (Fix Mistakes)

Bottom (parallel)

Lockout

Bar high or low on traps, feet shoulder-width and slightly turned out. Sit between the heels - knees track over the toes - until thighs are at least parallel. Drive up by pushing the floor away.

Common mistakes

  • Knees caving in on the drive up.
  • Cutting depth above parallel - quads under-recruited.
  • Heels coming off the floor - ankle mobility limit.

Where you should feel it

Whole leg pump, especially the front. Should NOT feel it in the lower back.

Injury risk · 6/10

SafetyKnees caving on the drive-up is the most common failure pattern - drop the load before pushing through it. If full-depth aggravates the knee, work the front-foot-elevated split squat instead.

Progression

Step back, or step up.

Same movement family, different rung. Harder versions sit above, easier versions below — tap a rung to land there.

  1. Progress toFront squatFront-loaded forces an upright torso and more quad recruitment.
  2. Progress toPause squat3 seconds in the hole kills the stretch reflex - pure quad strength.

Variations

Same movement, moved emphasis.

Ranked by how directly each variation still trains quads. 80%+ means the target barely changes. Below 60%, the emphasis has meaningfully shifted — useful for variety, but less precise for the specific part. The label calls it at a glance.

  • Front squat

    Bar across the front delts.
