Equipment
Machine

Overview

A seated machine fly that isolates the chest. The guided path keeps tension on the chest and makes it easy to focus on the squeeze.

How to do it

  1. Adjust the seat so the handles are at chest height when you sit.

  2. Sit tall with your back against the pad and grip the handles.

  3. Keep a slight bend in your elbows and your shoulder blades against the pad.

  4. Bring the handles together in front of your chest in a smooth arc.

  5. Pause and squeeze your chest, then return slowly until you feel a stretch.

Tips

  • Keep your chest up and avoid rounding your shoulders forward.
  • Control the return instead of letting the weight pull your arms back.

Common mistakes

  • Letting the handles travel too far back and overstretching your shoulders.
  • Shrugging your shoulders up toward your ears.
  • Using momentum to swing the handles together.
