Step-by-Step Execution Guide
Rest bar across upper traps (high bar) or rear delts (low bar), hands gripping tightly.
Unrack, step back, and set feet shoulder-width with toes angled outward 15–30 degrees.
Inhale deeply into belly, brace core, and initiate squat by breaking at hips and knees simultaneously.
Descend until hip crease is below parallel, keeping knees tracking over toes.
Drive aggressively through mid-foot to stand back up, exhaling past sticking point.
Common Mistakes & Form Fixes
