Barbell Drag Curl
The barbell drag curl is a strict biceps curl in which you drag the bar straight up the front of your body while your elbows travel back behind you. Moving the elbows back takes the front of the shoulders and momentum out of the lift, so the biceps and brachialis do the work through a shorter range than a standard curl.
Also called: Drag Curl, Barbell Drag Bicep Curl, Lean-Back Curl · Equipment: barbell · Pattern: pull
Step by step
- Stand tall with your feet about hip-width apart. Hold the bar with a palms-up grip at shoulder width, arms straight and the bar resting against your thighs.
- Brace your trunk lightly, keep your ribs down and let your shoulders sit slightly back.
- Curl by pulling your elbows back and up, so the bar slides straight up the front of your body in light contact with your torso.
- Keep the bar travelling vertically. Your elbows move behind your body rather than forward.
- Finish when the bar reaches the bottom of your breastbone and your elbows are well behind your torso. The top of this curl is deliberately shorter than a standard curl.
- Bring the bar back down along the same line, keeping it close to your body, until your arms are straight.
- After the last rep, bend your knees and hips with a flat back to set the bar down, or return it to the rack.
- Drag the bar up your shirt
- Pull your elbows back, not the bar forward
- Bar stays in contact with your body
- Finish at your chest with elbows behind you
- Ribs down, no lean back

What goes wrong, and the fix
Bar drifting away from the body
Fix: Keep the bar in light contact with your torso from thighs to chest.
Leaning back to heave the bar
Fix: Use a load you can drag with your ribs down and your torso upright.
Chasing a full curl at the top
Fix: Finish at the bottom of your breastbone with your elbows behind your body.
Shrugging the shoulders up
Fix: Keep your shoulders down and back and let only the elbows travel.
Bar dropping on the way down
Fix: Slide the bar down your body under control until your arms are straight.
What the research says
Muscle growthGeneral fitnessEndurance
- Load and reps — Research comparing loads finds muscle growth is similar across a wide range of loads when sets are taken close to failure. The drag curl's strict path limits the load, so it is usually trained with moderate to higher reps.
- Effort — Studies show growth rises as sets get closer to failure, but the curve flattens, and true failure adds only a small extra effect. Many lifters finish sets one to three reps short of failure.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns; about 10 or more hard sets a week has been associated with more growth than fewer than 5.
- Stretch and range — Research on the biceps links growth to training in the stretched part of the range, at the bottom of the curl. The drag curl keeps the full bottom range but shortens the top.
- The long-head claim — There is no direct research on drag curl muscle growth. One EMG study of another elbows-back curl found less, not more, biceps activity than a standard curl, and EMG does not measure growth.
