Incline Cable Fly

The incline cable fly is a chest isolation exercise where you lie on an incline bench between two low pulleys and bring the handles together above your upper chest. The cables give constant tension through the whole arc, including the top where dumbbells go slack, which makes it a strong finisher for the upper pecs.

Also known as: Incline cable crossover, Low-to-high cable fly on incline, Incline bench cable fly

Muscle group: Chest
Movement pattern: Horizontal adduction
Type: Isolation
Equipment: Cable machine, Adjustable bench
Difficulty: Intermediate

What muscles does the incline cable fly work?

Primary movers

Pectoralis major (clavicular)

Assisting muscles

Anterior deltoid
Biceps brachii (short head)
Serratus anterior

The cables pull outward and downward, and the pecs pull the arms together and up. On an incline bench the path lines up with the upper chest.

Unlike dumbbells, cables keep the pecs under tension at the top of the movement. The squeeze is more demanding and the muscle is not given a rest at the end of the rep.

The stretch at the bottom is still a benefit, but cables also let you control the load precisely and stop short of an excessive stretch.

Keep the elbows slightly bent and fixed. If they bend more, the triceps join in and the isolation is lost.

How to do the incline cable fly

Setup

1
Set both pulleys to the lowest position and place an incline bench centred between them.
2
Set the bench to 30 to 45 degrees.
3
Sit, pick up the handles and lie back.
4
Start with your arms out to the sides, a slight elbow bend and palms facing up.

Execution

1
Bring the handles together in a wide arc above your upper chest.
2
Squeeze your chest at the top.
3
Hold for a moment.
4
Lower slowly, keeping tension on the cables.
5
Keep the elbow bend fixed.
6
Keep your shoulders back on the bench.

Common incline cable fly mistakes

Pressing the handles

Bending the elbows turns it into a press.

The fix: Keep the elbow angle fixed and think of hugging.

Too heavy

Heavy cables pull the shoulders forward at the bottom.

The fix: Use a weight that keeps your shoulders on the bench.

Bench too steep

A steep angle puts too much work on the front delts.

The fix: Use about 30 degrees.

Pulling the bench out of line

A bench off-centre makes one side work harder.

The fix: Centre the bench between the pulleys.

A good finisher after incline presses. Use light weight, a pause at the top and a controlled stretch. Add weight in small steps and keep the rep tempo slow.

Frequently asked questions

What does the incline cable fly work?

The upper chest mainly, with the front delts and biceps assisting.

Cable fly or dumbbell fly?

Cables keep tension at the top. Dumbbells load the stretch more. Both are useful.

How do I set the bench?

Centred between two low pulleys, at an incline of 30 to 45 degrees.

How heavy should I go?

Light enough that your shoulders stay on the bench and your elbows stay fixed.

Can I do it standing?

Yes, a low-to-high cable crossover trains the upper chest in a similar way.

Hercules tracks every incline cable fly you log, shows you last session's numbers before you lift, and flags when your progress stalls.
