list_alt STEP-BY-STEP BIOMECHANICAL EXECUTION

Back Pad & Foot Placement

Sit in sled with back and hips firmly glued to the pads. Place feet shoulder-width on footplate, toes angled 15° out.

                    VECTOR CUE: Keep lower back flat on pad • Shoulder-width foot placement • Grip handles tight
                  

Unrack Safety Handles

Push sled up slightly to disengage safety levers at sides. Keep hands gripping side handles to anchor hips.

                    VECTOR CUE: Disengage safety handles • Hold side handles to pull hips down
                  

Controlled 90° Knee Descent

Lower sled slowly in 3 seconds until knees reach approximately 90 degrees. Stop before lower back peels off pad.

                    VECTOR CUE: 3s eccentric descent • Knees track over toes • Don't let pelvis round (butt wink)
                  

Drive to Soft Lockout

Drive through midfoot and heels to push sled back up, stopping just short of hyperextending knees.

                    VECTOR CUE: Drive through whole foot • Stop with soft knee bend • Never lock out hard
