Dumbbell Drag Curl
The dumbbell drag curl is a strict biceps curl in which you pull your elbows back and drag the dumbbells up the sides of your torso instead of swinging them out in front. It works the biceps and brachialis, keeps the front of the shoulder out of the lift, and uses a shorter top range than a standard curl.
Also called: DB Drag Curl, Dumbbell Drag Bicep Curl · Equipment: dumbbell · Pattern: pull
Step by step
- Stand tall holding a dumbbell in each hand at your sides, arms straight and palms facing forwards.
- Brace your trunk and set your shoulders back and down. Keep your chest up and your torso still for the whole set.
- Curl the dumbbells up by pulling your elbows backwards, so the dumbbells travel up close to the sides of your torso rather than out in front.
- Keep the dumbbells brushing your sides as your elbows move behind your body. Let your wrists settle at whatever palm-forward angle feels natural.
- Finish when the dumbbells reach the bottom of your ribs and your elbows are behind your torso. Hold that position for a moment.
- Bring the dumbbells back down along the same path, under control, until your arms are fully straight.
- After the last rep, let the dumbbells hang at your sides and set them down.
- Elbows back, dumbbells up your sides
- Chest up, shoulders back and down
- Dumbbells brush your torso all the way
- Finish at the bottom of your ribs
- Arms fully straight at the bottom
- Torso still, no swing

What goes wrong, and the fix
Elbows drifting forwards
Fix: Pull your elbows back behind your body as the dumbbells rise.
Dumbbells swinging away from the body
Fix: Keep the dumbbells brushing the sides of your torso on the way up and down.
Shoulders rolling forwards or shrugging
Fix: Set your shoulders back and down before the first rep and hold them there.
Leaning back to start the weight
Fix: Brace your trunk, stand tall and pick a load you can curl with a still torso.
Forcing the palms fully forwards
Fix: Let your wrists settle at the palm-forward angle that feels natural.
Cutting the bottom of the rep short
Fix: Straighten your arms fully at the bottom of every rep.
What the research says
Muscle growthGeneral fitnessEndurance
- Load and effort — Research comparing loads finds muscle growth is similar across a wide range of loads when sets finish close to failure. Studies show sets that end a few reps short of failure capture most of the growth benefit, so moderate dumbbells for moderate to high reps are the usual choice for this strict curl.
- Range of motion — Training studies of the elbow flexors found the straight-elbow part of the range produced greater biceps growth and strength than the bent-elbow part. The drag curl keeps that bottom range, which is why many lifters straighten the arms fully on every rep.
- Shoulder position — A training study that matched resistance profiles found curling with the shoulder back or forwards produced similar biceps growth and strength. A separate EMG study found a shoulder-back curl did not show more biceps activity than a standard dumbbell curl, so the elbows-back position is a technique choice rather than a proven growth advantage.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns. Rows and pull-ups also train the biceps, and counting them as partial sets improves how well weekly volume predicts growth.
