list_alt STEP-BY-STEP BIOMECHANICAL EXECUTION

Lie Back & Arm Angle

Lie flat on bench, press bar up with arms extended. Tilt upper arms slightly backward (10-15° behind vertical) to keep continuous tension on triceps.

                    VECTOR CUE: Arms tilted 15° back from vertical • Shoulders pinned • Feet flat
                  

Hinge at Elbows to Forehead / Bench

Keeping upper arms stationary, bend elbows smoothly to lower the bar toward your forehead or crown of head in 3 seconds.

                    VECTOR CUE: 3-second descent • Lower bar toward crown of head • Elbows tucked in
                  

Deep Long Head Stretch

Feel the intense stretch in the long head of your triceps at the bottom.

                    VECTOR CUE: Deep stretch behind head • Don't let elbows flare outward
                  

Drive to Extended Lockout

Push through your triceps to extend arms back to the 15° angled starting position without moving upper arm angle.

                    VECTOR CUE: Drive up • Squeeze triceps at lockout • Maintain 15° backward tilt
