Pec Deck

The machine chest fly — arms sweep together in front of the chest along the machine's fixed arc.

  • Category: Main circuit
  • Type: Machine-based chest fly
  • Targets: Chest, front delts
  • Prescription: 4 × 10

Setup

Adjust the seat so the handles sit at chest height with your upper arms level. Back flat on the pad, feet planted, a soft bend fixed in the elbows.

Execution

  1. Sweep both arms together in a wide arc until the handles meet in front of the chest.
  2. Squeeze the chest hard for a beat at the middle.
  3. Open back up with control until you feel a full chest stretch.

Cues

  • Elbow angle never changes — the chest swings the arms.
  • Shoulders stay back against the pad; they don't roll forward at the squeeze.
  • Slow the return; the stretch half of the rep counts.

Common Mistakes

  • Setting the seat so low the handles sit at the shoulders.
  • Shoulders rounding forward to chase extra range.
  • Letting the stack yank the arms open.

Progression

Add a plate once every rep meets in the middle with a one-second squeeze; the Dumbbell Fly trades the guided path for free control.
