Summary
This video presents two simple technique adjustments that can immediately improve chest muscle activation on any chest exercise. By modifying body positioning and hand pressure, lifters can shift the workload away from the front deltoids and onto the pectoral muscles. These cues apply universally to the bench press, cable crossover, and push-up.
Key Points
- The front deltoid commonly dominates chest exercises when form is not optimized, reducing pectoral development despite consistent training.
- Two key cues — sternum elevation and pressing through the inner fingers — can be applied immediately to your next workout.
- Elevating the sternum (lifting the rib cage up) pulls the shoulders back and brings the chest forward into a more prominent position, creating better mechanical advantage for the pecs.
- Pressing through the thumb and index finger (the two fingers closest to the dumbbell or cable) initiates shoulder adduction, which forces the chest to start and lead the contraction.
- If the shoulder initiates the movement, it will remain dominant throughout the entire range of motion, minimizing chest involvement.
- These cues work across all major chest exercises, not just the bench press — the same principles apply to cables and bodyweight movements.
- For the cable crossover, a staggered stance allows the chest to square forward while the shoulders stay behind, recreating the same mechanical position.
Exercise Details
Dumbbell Bench Press
- Target muscles: Pectorals (primary), front deltoids minimized
- Form cues:
- Position yourself at the bottom of the bench
- Exaggerate the height of your sternum by lifting the entire rib cage upward
- Press primarily through the thumb and index finger rather than evenly across the hand
- Common mistakes:
- Pressing evenly through the entire hand, allowing the front delt to initiate the movement
- Letting the shoulder come forward at the start of the press
Cable Crossover
- Target muscles: Pectorals
- Form cues:
- Use a staggered stance to create stability
- Square the chest forward — do not let it rotate back
- Stick the sternum out prominently
- Initiate the movement by pulling through the inner two fingers, creating a slight twist on the cable
- Common mistakes:
- “Bear hugging” through the movement without deliberate hand initiation
- Allowing the shoulder to drift in front of the chest
Push-Up
- Target muscles: Pectorals
- Form cues:
- Press the sternum toward the floor before beginning — avoid a hollowed chest position
- Use a hand release push-up if needed to reset into the correct starting position
- Press through the inside of the hand (thumb and index finger side) rather than evenly
- Keep shoulders back throughout the movement
- Common mistakes:
- Hollowing the back and letting the shoulder protrude in front of the chest — a particularly common issue for lifters with longer torsos or slimmer frames
- Even hand pressure that allows the shoulder to lead the press
