Seated Chest Fly Machine (Converging)
Coaching cues
- Seat adjusted so handles are at chest height; back flat against the pad
- Squeeze the handles together in a wide arc — pure horizontal adduction
- Pause at full contraction; lower slowly under machine resistance
- Converging path mimics a natural fly arc better than a fixed-axis machine
Common faults 2
Seat too low — elbows below chest level
The fly arc shifts to a lower angle; upper pec is undertargeted.
