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.

Watch for

  • 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

Equipment context

The barbell version lets you move the most absolute load, while your grip and shoulder girdle stabilize the path.
