Cable Flyes
The cable fly is an isolation exercise where you draw two handles together in a wide hugging arc. It builds the chest, with the front of the shoulder (anterior delts) helping. Because the cables keep the load on throughout, it suits beginners learning to feel their chest working, and more experienced lifters adding volume after pressing.
Muscles worked
The Cable Flyes mainly works your chest, with your anterior delts helping.
Setting up
- Set both pulleys to about shoulder height, attach single D-handles, and pick a light weight. 5 kg per side is plenty to start with, as flyes feel harder than they look.
- Take a handle in each hand and step forward into the middle of the machine until the cables pull your arms out to the sides, slightly behind your body.
- Stand in a staggered stance with one foot a step ahead of the other, knees soft and a slight lean forward from the hips. Your trainers should feel flat and planted.
- Lift your chest, keep your ribs down, and bend your elbows slightly. Hold that same elbow angle for the whole set.
How to do the Cable Flyes
- Start with your arms out wide at about shoulder height, palms facing forward, and feel a comfortable stretch across your chest.
- Take a breath in and keep your chest lifted, so your upper body stays tall and still.
- Breathe out and sweep your hands forward and together in a wide arc, as if hugging a large tree.
- Keep the slight bend in your elbows fixed. The movement should come from your upper arms swinging across, not from bending and straightening your elbows.
- Bring your hands together in front of your chest, or just short of touching, and squeeze your chest for one second.
- Breathe in and slowly let your arms travel back out along the same arc, taking about three seconds, until you feel a stretch across your chest.
- Stop at the point where the stretch is comfortable, then start the next rep without letting the weights rest on the stack.
Form tips
- Think about bringing your upper arms together rather than your hands. This keeps the work in your chest.
- Lead with your elbows and imagine your hands are just hooks holding the handles. A loose, light grip stops you turning the move into a press.
- Pause briefly in the squeeze, then control the way back. The slow return is where you keep tension on the chest.
- Choose a weight you can control for every rep. If your body rocks or your arms bend more as you tire, go lighter.
- Stop each rep when your hands are level with your chest. Pushing them further across adds little and usually makes your front delts take over.
Common mistakes
Going too heavy
Heavy weights turn the fly into a messy press and pull your body forward. Drop the weight until you can pause for a second at the squeeze and control the way back.
Bending and straightening the elbows
Changing your elbow angle shifts the exercise towards a press or a pull-over. Set a slight bend at the start and keep it the same throughout.
Over-stretching at the open position
Letting your arms go too far back pulls your shoulders forward and the weight tugs at the front of your shoulder joint. Stop when you feel a comfortable stretch across your chest, with your hands roughly in line with your body.
Swaying or leaning to move the weight
Using body momentum takes the load off your chest. Stay in your staggered stance with your chest lifted, and lower the weight until you can keep still.
Sets and reps
| Build strength | Cable flyes are better as an accessory than a main strength lift. Do 3 sets of 8-10 reps with 90-120 seconds rest, after your main pressing work. |
|---|---|
| Build muscle | 3-4 sets of 10-15 reps with 60-90 seconds rest, using a slow, controlled lowering phase and a pause at the squeeze. |
| Fat loss and general fitness | 2-3 sets of 12-15 reps with 45-60 seconds rest, as part of a full-body session alongside larger compound lifts and some cardio. |
Pick a weight where the last rep or two of each set is hard but your form stays clean. When every set feels easy, it's time to go up.

Cable Flyes FAQs
How heavy should I go on cable flyes?
Lighter than you think. Pick a weight where you can finish all your reps with the same elbow bend, no swinging, and a one-second squeeze at the front. Your last two reps should feel hard but still controlled.
Where should I feel cable flyes?
Mainly across the middle of your chest, with a stretch as you open your arms and a squeeze as your hands meet. Your front delts will help, so you may feel some work there. If it is mostly in the front of your shoulder, lower the weight and focus on moving your upper arms across your body.
Should I do cable flyes before or after pressing?
Most people do them after a main press such as bench press or chest press, when the heavy work is done. If you want to prioritise your chest, you can do them first with lighter weight, but expect to lift a bit less on your presses afterwards. Stop if anything hurts and get it checked.
