Pec Deck Alternative: 8 Chest Fly Swaps for the Gym or Home

The best pec deck alternative is a cable fly set at chest height, because it copies the thing the machine does well: tension that stays on your chest all the way into the squeeze. Training at home? A banded fly with the band anchored behind you at chest height is the closest swap, and it costs the price of a tube band set. For a shoulder that complains about deep stretches, lie on the floor and do floor flyes instead.

This page covers the chest fly pec deck, where you sit with your back to the pad and bring the handles together in front of you. If you're replacing the reverse pec deck for your rear delts, you want our rear delt fly guide instead.

What you're actually replacing

The pec deck is a fly with three helpful extras. The arc is fixed, so you can't wander off line. Your back is pinned to a pad, so there's no way to swing. And because the arms pivot around your shoulders, resistance stays high at the end of the rep, when your hands meet in front of your sternum.

A good swap keeps at least one of those. Cables and bands keep the squeeze tension. Dumbbells give it up but load the stretch harder. Floor and machine-free versions trade range for joint comfort.

Gym alternatives

1. Mid-height cable fly

Set both pulleys at roughly shoulder height, take a handle in each hand and step forward into a split stance until the cables pull your arms gently back. Keep a soft, fixed bend at the elbows and bring your hands together in front of your lower chest, as if hugging a large tree. Hold for a second, then let your arms open slowly until you feel the stretch.

This is the one to pick if your gym's pec deck is broken or always taken. The cable pulls horizontally, so the load doesn't disappear at the top. Our cable fly guide covers stance and handle choices in more detail.

• Cue: lead with your elbows, not your hands. If your hands get there first, your elbows are bending and it's turning into a press.
• Sets and reps: 3 to 4 sets of 10 to 15.

2. Low-to-high cable fly

Drop both pulleys to the bottom, grip the handles with palms forward, and sweep your hands up and together until they meet around upper chest or chin height. The upward path shifts work toward the upper (clavicular) chest, which a seated pec deck mostly misses.

• Cue: keep your shoulders down. If they shrug towards your ears as your hands rise, lighten the stack.

3. Single-arm cable fly

One cable, one side at a time. Stand side-on to the stack, brace your free hand on the upright or on your working pec, and bring the handle across the front of your body past the midline. Crossing slightly past centre gives you a fuller contraction than two arms can, because the hands don't collide.

It's slower, so save it for when you have a strength gap between sides or when you struggle to feel the chest working on the bilateral version.

Dumbbell alternatives

4. Flat and incline dumbbell fly

Lie on a bench with a dumbbell in each hand, palms facing, arms above your chest with a slight bend at the elbow. Lower the weights out to the sides in a wide arc until you feel a strong stretch, then sweep them back up. Stop about 20cm before the dumbbells touch at the top, because that's where the load is mostly resting on your bones rather than your pecs.

Set the bench to roughly 30 degrees to bias the upper chest. The full technique is in our dumbbell fly guide, and a solid adjustable weight bench makes switching angles easy.

How hard does a fly really work your pecs compared with pressing? A study of 17 trained men compared six-rep-max barbell bench press with dumbbell flyes and found the bench press produced higher activity in the pecs, front delts and triceps across most of the rep, while the biceps worked harder in the fly (Solstad et al., 2020). In plain terms: flyes are an add-on to pressing, not a replacement for it. Keep a press like the dumbbell bench press as your main chest lift and use the fly afterwards, which is the same slot the pec deck usually fills.

5. Floor fly

Do the same movement lying on the floor. Your upper arms stop when they touch the ground, which caps the stretch at about the line of your torso. That makes it the most shoulder-friendly fly here, and it needs no bench at all.

• Cue: let the backs of your upper arms kiss the floor, no bounce, then squeeze up.
• Who it suits: anyone with a cranky shoulder, or anyone training in a flat with dumbbells and nothing else.

6. Svend press

Hold a weight plate (or a dumbbell by its heads) between your palms at chest height, pressing your hands into it hard. Keep squeezing as you push it straight out in front of you until your arms are nearly locked, then bring it back to your chest. The weight is barely the point; the inward squeeze is.

It's awkward to load heavily, so treat it as a finisher. A 5kg to 10kg plate is plenty for most people, and a slow tempo with a two-second hold at full extension does more than piling on weight.

Home and bodyweight alternatives

7. Banded fly

Anchor a tube band at chest height behind you (a door anchor does this), hold a handle in each hand and step forward until the band is taut with your arms out to the sides. Fly your hands together in front of you and hold. Bands get harder the more they stretch, so the resistance peaks at the squeeze, which is the pec deck's strong point.

It's the best home swap for that reason. A tube set with handles and a door anchor covers it, and you'll use the same kit for rows and presses.

The Whatafit set is our top pick in the best resistance bands UK guide because it ships with handles, a door anchor and five stackable bands. If you'd rather have the real cable version at home, our best cable machine UK roundup covers wall-mounted and crossover options.

8. Fly push-up and squeeze push-up

Two ways to get a fly-like squeeze from a push-up:

• Slider fly push-up. Put each hand on a slider or folded towel on a smooth floor. Lower by letting your hands slide apart, then drag them back together as you push up. Start on your knees; the full version is brutal.
• Squeeze push-up. Do a normal push-up but actively try to pull your hands towards each other against the floor throughout, without them actually moving. You'll feel your inner chest switch on.

Don't write push-ups off as the soft option, either. In a five-week trial with trained students, 6RM push-ups loaded with elastic bands produced strength gains similar to 6RM bench press once muscle activity was matched (Calatayud et al., 2015).

Which one should you pick?

Match the swap to your situation:

• In a gym without a pec deck: mid cable fly, then low-to-high for the upper chest.
• Home with dumbbells: incline dumbbell fly on a bench, or floor fly without one.
• Home with nothing but a door: banded fly.
• Shoulder pain: floor fly, or a banded fly with a short range. Skip deep dumbbell and low cable stretches until it settles.
• Just your bodyweight: slider fly push-up and squeeze push-ups.

Machines aren't magic, and neither are free weights. A meta-analysis comparing the two found no meaningful difference in muscle growth (Haugen et al., 2023), so pick the version you can do consistently with good form.

Common mistakes

Turning the fly into a press. If your elbow angle opens and closes, your triceps take over. Lock in a slight bend and keep it.

Chasing the stretch. Going deeper than the line of your torso loads the front of your shoulder, not your pec. More range isn't automatically better here.

Going too heavy. Flyes are an isolation move. If you're swinging, shrugging or arching off the bench, the weight is wrong.

Letting the shoulders roll forward at the squeeze. Keep your shoulder blades pulled back and down. Rounding forward at the end shifts work into your front delts.

How to programme it

Put your fly after your main press, in the slot the pec deck had. Two or three sets of 10 to 15 reps is plenty for most people, with 60 to 90 seconds between sets and a one-second hold at the squeeze. If you train chest twice a week, use a stretch-biased fly (dumbbell) in one session and a squeeze-biased one (cable or band) in the other, so you cover both ends of the range.
