Muscles
- Primary
- quads
- Supporting
- glutes, hamstrings, lower back
Mechanics
- Pattern
- squat
- Equipment
- barbell, rack
- Geometry
- 90° Alignment
- Target feel
- Hip drive dominates; torso stays more horizontal than high-bar.
- Progression
- Add 2.5–5 kg when all reps hit depth with stable torso angle.
- Regression
- High-bar squat if hip mobility doesn't allow the forward lean.
Common errors
- Good-morning squat — hips rise faster than shoulders out of the hole
- Bar rolled too high onto traps — causes wrist and elbow pain
- Knees caving inward on the ascent
