Cable Standing Alternate Chest Fly
- Intermediate
- Isolation
- Rep-based
- Chest
- Shoulders
The Cable Standing Alternate Chest Fly is an isolation movement that targets the pectorals and anterior deltoids while challenging core stability through unilateral loading. Alternating sides allows for a greater focus on the mind-muscle connection and ensures balanced development across the chest.

Setup
- Set the cable pulleys to shoulder height on a dual cable machine.
- Stand in the center of the machine with a staggered stance (one foot forward) for maximum stability.
- Grasp the handles with a neutral grip (palms facing each other) and step forward until there is tension on the cables.
- Extend your arms out to the sides with a slight bend in the elbows, keeping your chest up and shoulders back.
How to do it
- Exhale and bring one handle in a wide arc toward the midline of your body, stopping when your hand is directly in front of your sternum.
- Squeeze the pectoral muscle at the peak of the contraction for one second.
- Inhale and slowly return the handle to the starting position using a controlled 2-3 second tempo.
- Repeat the movement with the opposite arm, alternating sides for the duration of the set.
Form checklist
- Maintain a fixed, slight bend in the elbows to avoid bicep strain.
- Keep your torso stationary and core braced to prevent the body from rotating toward the moving arm.
- Ensure the movement occurs at the shoulder joint only; do not turn it into a pressing motion.
- Keep your shoulder blades retracted and depressed throughout the entire range of motion.
Pro tips
- Think about bringing your inner bicep toward your chest rather than just moving your hand to maximize pectoral recruitment.
- Focus on the 'stretch' at the end of the eccentric phase, but stop before the shoulder joint feels unstable.
Make it harder
- Cross the moving hand slightly past the midline of the body to increase the peak contraction of the inner chest.
- Perform the movement with a parallel foot stance to significantly increase the demand on your core stabilizers.
