Standing cable crossover flye for the sternal pectoralis major; trunk angle changes the emphasis and the secondary muscles.
Detail
The source gives two trunk positions:
- Trunk at 45 degrees — Primary: Pectoralis Major (MEO Sternal); Secondary: Anterior Deltoid, Latissimus Dorsi, Rhomboid.
- Trunk Parallel to the Floor — Primary: Pectoralis Major (MEO Sternal); Secondary: Anterior Deltoid.
Cross-over cable (45 degrees to upright position) is the example exercise for shoulder-joint adduction (a weak action assisted by the latissimus dorsi). Cross-over cable/flyes occupy the "stretch" and "contracted" positions of the Positions-of-Flexion pectoral chart. For maximum pectoral effect, use scapular adduction to increase the force angle (2-joint muscle).
Key facts
- Primary: Pectoralis Major (MEO Sternal) in both positions.
- Secondary at 45 degrees: Anterior Deltoid, Latissimus Dorsi, Rhomboid.
- Secondary parallel to floor: Anterior Deltoid.
- "Stretch"/"contracted" positions in the pectoral Positions-of-Flexion chart.
Connections
- Pectoralis Major — primary mover (sternal).
- Anterior Deltoid / Latissimus Dorsi — secondary movers.
- Horizontal Flexion (Adduction) — the primary joint action.
- Dumbbell Flyes / Pec Deck — related chest isolation moves.
