Dumbbell pullover: chest or lats, the setup, and the straight-arm and bent-arm versions

The dumbbell pullover is lying on a bench with one dumbbell held over your chest, lowering it back over your head in an arc, and pulling it back. Your elbows stay almost fixed, so the movement happens at the shoulders. It's an exercise that both chest days and back days claim, and the question people ask most is which one it belongs to.

This page covers the setup, what the studies found about the chest and the lats, straight or bent arms, the bench, floor and cable versions, the faults, and the sets. Where it fits a week is on the chest workout and the back workout.

How to do a dumbbell pullover

1. Lie along a flat bench, head supported, feet flat on the floor. (Lying across the bench, with only your upper back on it and your hips low, is the other common setup.)
2. Hold one dumbbell with both hands under the top plate, palms against it and thumbs around the handle, arms extended over your chest.
3. Bend your elbows slightly and keep that bend for the whole set.
4. Brace, ribs down and lower back where it was, then lower the dumbbell back behind your head in an arc.
5. Stop when your upper arms are about level with your ears, or sooner if your ribs start to lift or your back arches.
6. Pull it back along the same arc until it's over your chest again. That's one rep.

Chest or lats?

Both, and the chest seems to do at least as much. In 8 healthy men doing a barbell pullover with 30% of their body weight for ten reps, the chest was more active than the lats, and how active each muscle was depended on the leverage of the weight at each point of the arc.¹

Shoulder angle matters more than the name of the exercise. In 15 resistance-trained men pushing as hard as they could without moving, at five shoulder angles from 0 to 180 degrees, lat activity changed with the angle, with no significant difference in that pattern between a pullover and a pulldown. Chest activity depended on the exercise and the angle together.²

A 2026 review of 23 studies of lat activity read the three small pullover studies, about 43 people in all and all or mostly men, and found the pullover appeared to work the chest more than it singled out the lats. The authors describe it as a combined lat and chest movement, and in one of those studies, of 20 healthy, physically active adults, a barbell pullover produced more activity than the straight-arm pulldown in most muscles measured, but not in the lats or the triceps.³ So if the lats are your goal, the straight-arm pulldown or the lat pulldown is the more direct choice, and the pullover is a chest-and-back extra.

Straight arms or bent arms

The steps keep a slight bend. Bending the elbows more brings the front of the shoulder in. In 24 men doing two pullover versions, upper-chest activity was weak to moderate in both, and front-shoulder activity was moderate in the standard version and strong with bent arms.⁴ Keep the bend small and fixed, so the weight moves in an arc rather than up and down.

Bench, floor, cable or machine

The common faults, and a fix for each

• Arching your back to go deeper. Stop the arc where your ribs start to lift. The depth comes from your shoulders, not your spine.
• Turning it into a press. If your elbows bend and straighten on every rep, the weight moves up and down instead of around. Fix the bend and keep it.
• Going too heavy. One dumbbell held by both hands at the end of long arms gets hard fast. If you can't control the bottom of the arc, go lighter.
• Letting the dumbbell drop at the bottom. Lower it under control and pull it back smoothly; no bounce.
• A loose grip. Cup the top plate with both palms and wrap your thumbs around the handle, and check your hold before the first rep.
• Pushing through something that hurts. Sore muscles the next day are normal; a sharp or lasting hurt in the shoulder isn't. Stop, and see a doctor or a physical therapist.

Sets, reps and where it goes

• Two or three sets of 10 to 15 near the end of a chest or back session, stopping one or two reps short. (How to judge reps left.) The American College of Sports Medicine's 2026 position stand, which covers healthy adults, advises at least two sets per exercise.⁵
• Count it as an extra, not as your main chest or back lift. No trial that trained the pullover on its own and measured the chest or the lats turned up in a PubMed search for this page, so presses and pulls stay the base: the same stand found muscle growth was enhanced by ten or more sets per muscle group a week.
• Pick the day by what you feel working. After presses on a chest day, or after rows and pulldowns on a back day; either fits, as the studies above suggest.
• Add weight in small steps. When 15 reps come easy through the full arc, go up by the smallest jump you have. (Progressive overload covers the options.)

If you'd rather not plan it alone

The pullover is one exercise; deciding whether it earns a slot, and on which day, depends on everything else in your week. Coaching is the version where your workouts are built around the days you actually have, and a weekly call looks at the week you just had and rebuilds the next one. Coaching to build muscle explains how that works, and here's how to apply. Otherwise: at the end of your next chest or back session, try two sets of 12 pullovers with a light dumbbell, stopping where your ribs stay down, and write down the weight.
