Cable Fly
The cable fly is a chest isolation exercise: standing between two cable pulleys, you sweep your arms from wide out to your sides until your hands meet in front of your chest, keeping a soft, fixed bend in the elbows. It works the chest with help from the front of the shoulders, and the cables keep tension on the chest from the stretched start all the way to the squeeze.
Also called: Cable Crossover, Cable Chest Fly, Cable Crossover Fly, Standing Cable Fly · Equipment: cable · Pattern: push
Step by step
- Set both pulleys to the same height. Shoulder height gives a level arc, and low pulleys give a low-to-high arc that sweeps up towards your chin.
- Take a handle in each hand and step forward into a split stance, far enough that the cables pull your arms back and out to your sides.
- Pull your shoulder blades back and down, bring your ribs down and set a soft bend in your elbows. Hold that elbow bend for the whole set.
- With your arms out wide and a stretch across your chest, sweep your hands forward and together in a wide arc, leading with your upper arms.
- Bring your hands together in front of your chest, or let them cross slightly, and squeeze your chest for a moment.
- Let your arms travel back out along the same arc under control, until you feel a comfortable stretch across your chest.
- Keep your torso still through every rep, then step back towards the stacks to let the weights down after the last rep.
- Hug a big barrel, elbows fixed
- Lead with your upper arms
- Shoulder blades back and down
- Stretch under control to a comfortable end
- Squeeze your hands together at the midline
- Torso still, arms do the work

What goes wrong, and the fix
Bending and straightening the elbows
Fix: Set a soft elbow bend at the start and hold that exact angle for every rep.
Letting the cables pull the arms back fast
Fix: Take the arms back slowly and finish at a comfortable stretch.
Shoulders rolling forward
Fix: Pull your shoulder blades back and down before the first rep and hold them there.
Lunging the torso forward
Fix: Keep your torso still and use a load you can move with your arms alone.
Hands meeting without a squeeze
Fix: Bring the hands fully together, or cross them slightly, and squeeze.
Elbows dropping below the hands
Fix: Keep your elbows level with or just above your hands through the arc.
What the research says
Muscle growth · first choiceRehab & prehabGeneral fitnessEndurance
- Role — Research comparing presses and flies finds the barbell bench press produces equal or higher chest muscle activity than the fly. The fly is usually programmed alongside a press, to add chest volume, and not in place of one.
- Load and effort — Research comparing loads finds muscle growth is similar across a wide range of loads when sets are taken close to failure. Many lifters use moderate to high reps on flies, commonly about 10–20.
- Range of motion — Research generally finds training through a full range, including the stretched position, gives equal or greater growth than short partial reps. Upper-body data are limited.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns. Counting pressing and fly sets together gives a clearer weekly chest total.
- Cable angle — EMG studies on bench angle find the upper chest is most active on a low-to-high line and the middle and bottom of the chest on a level or high-to-low line. This is muscle activity, not measured growth.
