Dumbbell Bench Press
The dumbbell bench press is a flat-bench press with a dumbbell in each hand: you bring the dumbbells down beside your chest and press them back up over your shoulders. It works the chest, the front of the shoulders and the triceps, allows a deeper stretch than a barbell, and makes each arm carry its own load.
Also called: DB Bench Press, DB Bench, Flat DB Press, Flat Dumbbell Press · Equipment: dumbbell · Pattern: push
Step by step
- Sit on the end of a flat bench with a dumbbell standing on each thigh. Lie back, and as your back reaches the bench, use your knees to help push the dumbbells up so they arrive over your chest with straight arms.
- Plant your feet flat on the floor. Pull your shoulder blades back and down into the bench and keep your upper back tight, with your glutes and head on the bench.
- Hold the dumbbells with your palms facing your feet, or turned slightly in, with your wrists stacked straight over your elbows.
- Take a breath and brace. Bring the dumbbells down under control to the sides of your chest, with your elbows about 45–70° from your torso and your forearms vertical.
- Go down until the dumbbells are level with your chest or you feel a strong stretch across it, without forcing extra depth.
- Press the dumbbells up and slightly together so they finish over your shoulders, just short of touching. Keep your shoulder blades set and your feet planted.
- After the last rep, bring the dumbbells to your chest, pull your knees up to meet them and rock up to sitting with the dumbbells resting on your thighs.
- Shoulder blades back and down into the bench
- Elbows 45–70° from your sides, forearms vertical
- Dumbbells to the sides of your chest
- Press up and slightly together
- Knees help the dumbbells up and meet them at the end
- Feet planted, glutes on the bench

What goes wrong, and the fix
Elbows flared out towards 90°
Fix: Angle the elbows about 45–70° from your sides and keep forearms vertical.
Forcing extra depth with heavy dumbbells
Fix: Bring the dumbbells to chest level or a strong stretch, and no deeper.
Shoulder blades losing their set
Fix: Set your shoulder blades back and down before the first rep and hold them there.
Hauling the dumbbells into position
Fix: Rest the dumbbells on your thighs and use a knee kick as you lie back.
Dropping the dumbbells out to the sides after the set
Fix: Bring the dumbbells to your chest, pull your knees up and sit up with them.
One side lagging
Fix: Press both dumbbells at the same speed and match the range on both sides.
Bouncing out of the bottom
Fix: Reach the bottom under control, then press from a brief, solid pause.
What the research says
Muscle growth · first choiceGeneral fitness · first choiceStrengthRehab & prehabSport performanceEnduranceFat loss & conditioning
- Load by goal — Research comparing loads finds maximal strength favours heavier loads (about 8 reps or fewer per set), while muscle growth is similar across a wide range of loads when sets are taken close to failure.
- Effort — Studies show sets that finish a few reps short of failure capture most of the size and strength benefit, and strength gains appear largely insensitive to how close to failure you train. Rep-in-reserve estimates tend to under-count and are most accurate on heavier sets.
- Dumbbell or barbell — EMG studies found chest and front-shoulder activity similar in dumbbell and barbell bench presses, with more biceps activity and a dumbbell one-rep max about 17% below the barbell. The choice rests more on range, equipment and preference than on muscle activity.
- Volume and frequency — Research links more weekly sets for a muscle to more growth, with diminishing returns, and training a muscle about twice a week is a common way to spread that volume.
- Rest — In trained lifters, rests of about 3 minutes between sets have produced greater strength and size gains than 1-minute rests, largely because each set can carry more load.
- Pairing with a row — An acute trial found alternating a press with a row completed more work in less time without a loss of performance in each set.
