Bent-Arm Dumbbell Pullover
The bent-arm dumbbell pullover has you lying across a bench holding one dumbbell with both hands over your chest, elbows bent, then swinging it down in a slow curve until it hangs past your head before pressing it back over your chest to start. It's built around the chest, with the lats, shoulders, and triceps working through the same range, and the return over the chest has a genuine pressing component to it, which is what separates this version from a pure lat stretch.
Why it works
As the dumbbell arcs down behind your head, your rib cage and shoulders open into a deep stretch, but the return path back over your chest asks your pecs to pull your arms back together and finish by pressing the weight up, which is closer to the closing motion of a chest fly than a simple pulldown. Bending the elbows shortens the lever compared to a straight-arm version, which lets you load the movement a bit more while keeping the stress mostly in the shoulder joint's safe range rather than turning it into a mobility test. That combination, a real chest-driven finish layered on top of an overhead stretch, is what makes this exercise feel different depending on whether you focus on the stretch or the squeeze.
Set up
- Lie across a flat bench so your upper back and shoulders are supported, hips low, feet flat on the floor.
- Hold one dumbbell with both hands, cupping the inner plate, arms extended over your chest with elbows slightly bent.
- Brace your core so your hips don't sag as the weight moves overhead.
- Choose a weight noticeably lighter than what you'd use for a chest press; this is a controlled arc, not a heavy push.
How to do it
- Swing the dumbbell back in a slow curve until it hangs past your head, keeping the same slight elbow bend throughout.
- Stop the descent at the point where your ribs stay down and your lower back doesn't arch off the bench.
- Pause briefly at the deepest comfortable point of the stretch.
- Press and pull the dumbbell back along the same arc until it's over your chest again, squeezing your pecs at the top.
- Keep your hips and core braced through the entire rep, in both directions.
- Reset your grip and breathing before starting the next rep.
Form cues
- Elbows hold the same slight bend the whole time.
- Stop the stretch where your ribs stay down.
- Finish the return by squeezing your chest together, not just bending your arms.
- Hips stay braced, no sagging as the weight moves overhead.
Breathing: Inhale as the dumbbell lowers behind your head into the stretch, exhale as you press and pull it back over your chest.
Common mistakes
Letting the ribs pop up and the lower back arch off the bench during the stretch.
Fix: Shorten the range so the descent stops where your core can still keep your ribs down and your back flat on the bench.
Using a dumbbell heavy enough that the movement turns into a shaky, uncontrolled swing.
Fix: Drop the weight significantly; the value here is the stretch and the controlled squeeze, not how much load you can move.
Treating the return as a simple pull with no chest engagement at the top.
Fix: Actively squeeze your pecs together as the dumbbell comes back over your chest, rather than just letting your arms carry it there.
Losing the elbow angle mid-set, letting the arms straighten out further as fatigue sets in.
Fix: Keep a consistent, moderate elbow bend for every rep, and end the set once you can't hold that position anymore.
How to program it
- This works well as a lighter accessory movement; 2 or 3 sets of 10 to 12 reps is enough to get the stretch and the chest squeeze without heavy joint stress.
- Place it toward the end of a chest or pull day, after your main pressing or rowing work is done.
- Because the load stays light, two sessions a week is reasonable if your shoulders are handling the range comfortably.
- If your goal leans more toward chest development, pause and squeeze harder at the top; if it leans toward lat stretch, spend more time in the deep, lowered position instead.
Safety notes
- Keep the dumbbell light and the arc shallow until you're confident your shoulders handle the overhead stretch comfortably.
- Have a clear idea of your stopping point before you start; overshooting the stretch is the main risk with this exercise.

Frequently asked questions
How many sets and reps for the bent-arm dumbbell pullover?
2 or 3 sets of 10 to 12 reps with a light dumbbell works well. This exercise trades heavy loading for a controlled stretch and squeeze, so higher reps with strict form beat fewer reps with more weight.
What can I do instead of the bent-arm dumbbell pullover?
A straight-arm dumbbell pullover uses the same bench and dumbbell setup with a longer lever, and it's a fair swap if bending your elbows through the arc doesn't feel comfortable for your shoulders.
Does the dumbbell pullover work chest or back?
Both, but this bent-arm version leans toward the chest, since the return over your chest ends with a genuine pressing and squeezing motion. Your lats, shoulders, and triceps are all working too, just as secondary movers.
Why do my shoulders feel tight during the dumbbell pullover?
That usually means you're lowering the weight past your current shoulder mobility. Shorten the range so you stop at the deepest point your shoulders can move through without the front of the joint feeling strained.
