list_alt STEP-BY-STEP BIOMECHANICAL EXECUTION

Support Mount & Scapular Lock

Mount captain's chair with forearms on pads (or hang from pull-up bar). Depress shoulders away from ears.

                    VECTOR CUE: Forearms firm on pads • Back supported • Legs hanging straight
                  

Pelvic Curl Initiation

Do not just lift legs; initiate by tilting pelvis upward, curling knees/legs up toward chest.

                    VECTOR CUE: Roll pelvis upward • Bring knees all the way to chest level
                  

Peak Abdominal Crunch

Squeeze abs at the top for 1 full second when knees reach chest height.

                    VECTOR CUE: 1-second peak squeeze • Posterior pelvic roll
                  

Strict Controlled Negative

Lower legs slowly without swinging or using pendulum momentum.

                    VECTOR CUE: Slow 2-second descent • Stop completely before next rep
