Cable Middle Fly
- Beginner
- Isolation
- Rep-based
- Chest
- Shoulders
The Cable Middle Fly targets the sternal head of the pectoralis major, using the constant tension of the cables to maximize muscle fiber recruitment and chest definition. This isolation movement is highly effective for developing the inner chest and improving shoulder stability.

Setup
- Set the cable pulleys to shoulder height on both sides of the machine.
- Grasp the handles with a neutral grip and step forward into a staggered stance for a stable base.
- Lean slightly forward from the hips, keeping your chest up and core engaged.
- Position your arms out to the sides with a slight bend in the elbows, hands level with your shoulders.
How to do it
- Exhale as you bring the handles together in a wide arc in front of your chest, maintaining the slight bend in your elbows.
- Squeeze your chest muscles forcefully at the point where your hands meet or slightly overlap.
- Inhale as you slowly reverse the movement, controlling the weight back to the starting position until you feel a comfortable stretch.
- Maintain a controlled 2-1-2 tempo: two seconds to close, one second squeeze, and two seconds to return.
Form checklist
- Keep your shoulders retracted and depressed (down and back) to protect the joints.
- Maintain a consistent slight bend in the elbows; avoid turning the movement into a press.
- Keep your torso stationary and avoid using momentum or swinging to move the weight.
- Ensure your hands follow a horizontal path directly in line with your mid-chest.
Pro tips
- Focus on bringing your inner elbows toward each other rather than just your hands to maximize pectoral contraction.
- Imagine you are hugging a large tree to maintain the correct arc and keep the tension on the chest rather than the front delts.
Make it harder
- Add a 3-second isometric hold at the peak of the contraction where the hands meet.
- Slow down the eccentric (return) phase to 4-5 seconds to increase time under tension.
