list_alt STEP-BY-STEP BIOMECHANICAL EXECUTION

01

Bar Placement & Shelf Creation

Step under bar, rest it across upper traps (High Bar) or rear delts (Low Bar). Squeeze shoulder blades together hard to form a rigid muscular shelf.

VECTOR CUE: Form tight upper back shelf • Grip bar firmly • Stand erect with 2-step walkout
02

Stance & 360° Core Brace

Set feet shoulder-width apart, toes flared 15-30° out. Take deep belly breath, expand abdomen 360°, and screw feet into floor.

VECTOR CUE: Shoulder-width stance • Screw feet into floor • 360° intra-abdominal brace
03

Parallel / Sub-Parallel Descent

Break at hips and knees simultaneously. Descend under strict control in 3 seconds until hip crease is below the top of the kneecap.

VECTOR CUE: Track knees in line with toes • Keep chest proud • Hit parallel depth
04

Explosive Ground Drive

Drive through midfoot and heels, exploding vertically out of the hole while maintaining torso angle until standing tall.

VECTOR CUE: Drive midfoot into floor • Lead with chest • Lockout hips and glutes
