How many sets of the decline cable fly should you do when you are new to the exercise?

Keep each set under about 40 seconds because of the head-down position, which puts you at three sets of 10 to 12 to finish a chest session. The setup takes a few minutes, so run all your sets in one go rather than pairing it with something on the far side of the gym.

What can I do instead of the decline cable fly?

A standing cable crossover from high pulleys hits the same lower-chest line without a bench and takes seconds to set up. If you want to stay lying down, a decline dumbbell fly is the swap, accepting that the tension drops off at the top of every rep.

What is the decline cable fly for, and who should avoid it?

It isolates the lower chest with tension that never lets up, which makes it a finisher rather than a builder, sitting after your presses on a hypertrophy day. Anyone who gets a headache or reflux with their head below their hips is better off standing up and using the crossover. Leave it alone too when the only decline bench available cannot anchor your legs, because you will slide down the pad under load.

Intermediate

Decline Cable Fly

Anchoring a decline bench inside a cable station lets you fly on a downward angle that targets the lower sternocostal fibers, with the cables holding tension from the deep stretch through the top squeeze. Lying on the bench removes balance from the equation so you can focus on a clean adduction to the lower chest. Use it as a lower-chest isolation to finish a pressing session.

How to do it

1
Set both pulleys to their lowest position and secure a decline bench between the uprights with your legs anchored.
2
Grab a handle in each hand and lie back with arms extended over your lower chest, palms facing each other.
3
Keep a slight, fixed bend in your elbows and lower the handles out to the sides in a wide arc.
4
Lower until you feel a stretch across the chest and your upper arms are about level with your torso.
5
Squeeze the chest to draw the handles up and together over your lower sternum.
6
Stop just short of the handles touching to keep tension on the pecs.

Tips

Hold the elbow angle constant so the movement stays a fly, not a press.
Draw the handles toward the lower chest and hips to match the lower-fiber line of pull.
Anchor your legs firmly so you do not slide down the decline during the set.

Variations

Common mistakes

Lying head-down makes long sets uncomfortable and can leave you light-headed on the way up; keep the sets short and sit up slowly between them.
The handles finish over the middle of the chest instead of down at the lower sternum, which pulls the work back toward the fibers this angle was chosen to avoid.
Pulleys are left at shoulder height instead of at the floor, so the cable pulls the arms sideways instead of down and the bottom of the rep loses its stretch.
Once the arms reach the bottom of the arc, the elbows drop below the line of your torso and the shoulder takes over the pull; stop level with your body.
