Cable Incline Alternative Fly
- Intermediate
- Isolation
- Rep-based
- Shoulders
This isolation movement targets the upper pectorals and anterior deltoids, using constant cable tension to maximize muscle fiber recruitment throughout the entire range of motion. The alternating pattern increases time under tension and demands greater core stability to prevent torso rotation.

Setup
- Position an incline bench at a 45-degree angle between two low cable pulleys.
- Sit back firmly against the bench with your feet planted wide for stability.
- Grasp the handles with a neutral grip (palms facing inward) and start with arms extended out to the sides, slightly below shoulder height.
- Maintain a slight, fixed bend in the elbows to protect the joints.
How to do it
- Exhale as you bring one handle toward the midline of your chest in a wide arc, keeping the elbow angle locked.
- Squeeze the upper pectoral at the top of the movement for a one-second pause.
- Inhale as you slowly lower the weight back to the starting position under control.
- Repeat the movement with the opposite arm, alternating sides for the duration of the set.
Form checklist
- Keep your back and head pressed firmly against the bench throughout the set.
- Maintain a consistent slight bend in the elbows; do not turn the movement into a press.
- Avoid rotating your torso toward the moving arm to ensure the chest does the work.
- Stop the lowering phase when you feel a deep stretch, before the shoulder feels unstable.
Pro tips
- Focus on bringing the bicep toward the midline of the chest rather than just moving the hand to maximize pectoral contraction.
- Imagine hugging a large tree to maintain the correct arc and keep tension on the target muscles.
- Lead the movement slightly with your pinkies to better isolate the upper chest fibers.
Make it harder
- Add a 3-second eccentric (lowering) phase to increase time under tension and metabolic stress.
- Perform a '1.5 rep' style where you bring the handle halfway back down, return to the top, then lower fully.
Frequently asked
- What muscles does the cable incline alternative fly work?
- The cable incline alternative fly primarily targets the pectorals, and also works the deltoids and serratus anterior as secondary muscles.
- What equipment do you need for the cable incline alternative fly?
- The cable incline alternative fly uses cable.
- Is the cable incline alternative fly good for beginners?
- The cable incline alternative fly is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
