Bent-Arm Dumbbell Pullover
Also works: Lats · Shoulders · Triceps
One dumbbell held in both hands, lowered in an arc behind your head while you lie across a bench with only your shoulder blades on it. Keeping the elbows bent at a fixed angle throws the work onto the sternal pecs and serratus rather than the lats, and the hips-below-the-bench position is what creates the long stretch at the bottom.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Stand one dumbbell on its end on the bench first, so you can grip it without wrestling it into position from the floor.
- Lie across the bench, not along it: only your upper back and shoulder blades touch, head hanging off the far side.
- Plant both feet flat, knees at about 90 degrees, and let your hips sit lower than the bench surface.
- Cup both palms flat against the underside of the top plate, thumbs wrapped around the handle as a backup.
- Press the dumbbell straight over your sternum with your chosen elbow bend, then brace your abs before the first rep.
Every rep
Breathing & tempo — Breathe in as the dumbbell travels behind your head and out as you pull it back over your chest. Three seconds down, one second paused in the stretch, a controlled second up.
Before you load it
- The dumbbell passes directly over your face. Never use a loose adjustable dumbbell, and if the set fails, let the weight continue behind your head onto the floor rather than trying to save it.
- If you have a history of shoulder impingement or an unstable shoulder, cut the depth to just past horizontal. End-range overhead loading is exactly where that joint complains.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Start with 10-12 kg even if you bench well — the leverage is unforgiving and the first session is about finding your bottom position. Most trained lifters live between 20 and 30 kg here. Add weight only when you can pause a full second at the deepest point without the hips lifting or the elbows opening; otherwise add reps.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Keep the hips low and the glutes soft on purpose. If they creep up, cut the set — a rising hip shortens the arc and quietly removes the stretch you came for.
Pick your elbow angle before rep one and hold it like a cast. Drop 4-6 kg if you cannot; long-lever pullovers with heavy weight are how shoulders get sore.
Set the bottom position at the point where your ribs start to flare, and stop 5 cm short of it. Brace your abs so the ribs stay down instead of the spine giving range away.
Let your knees stay soft and think of your legs as a tripod, not an engine. If you cannot start the arc without a hip thrust, you are 4-6 kg over the weight your chest can actually reverse.
Why bother
Almost every chest movement you own is a press or a fly in the horizontal plane. The pullover loads the pecs through shoulder flexion instead — arms overhead, ribs pulled long — which is the one direction a bench press never reaches. That deep overhead stretch under load is the whole reason to keep it around.
The bent-arm version is not an accident of laziness. A straight arm turns the dumbbell into a very long lever and forces you to drop the load to something that no longer challenges the chest; locking a roughly 20-30 degree elbow bend and refusing to let it change keeps the torque high enough to matter while keeping the shoulder out of an end-range hang.
Where it fits
Late in a chest or upper-body session, after your presses, as a stretch-biased finisher of 3 sets of 10-15. Once or twice a week is plenty. Do not pair it with heavy overhead pressing in the same session — both hammer the same end-range shoulder position and the pullover always loses that argument.

Asked and answered
Is the pullover a chest exercise or a back exercise?
Both muscles work, and the elbow decides the split. A bent arm with the ribs pulled down and the hips low biases the sternal pecs and serratus; a straight arm with the torso flat and a deliberate lat squeeze biases the lats. Neither version is an efficient back builder — if you want lats, row or pull down. Use this one for the chest stretch.
Does the pullover expand your ribcage?
No. That was a 1970s bodybuilding claim built on the idea that heavy breathing squats plus pullovers would stretch the cartilage of the ribcage. Adult rib geometry does not change from a dumbbell. It is still a good stretch-biased chest movement — just not for the reason the old magazines gave.
Do I have to lie across the bench, or can I lie along it?
Lying along the bench is safer, easier to balance and perfectly valid — you just lose some range because your hips cannot drop. Lying across it lets the hips sink and the ribs open, which is where the extra stretch comes from. Start along the bench, move across it once the pattern is automatic.
Should this go before or after my bench press?
After. It is a stretch-biased accessory with a poor strength-to-fatigue ratio at the shoulder, and doing it first leaves you pressing with a shoulder that has just been loaded at end range. Presses first, pullovers as the finisher.
