The drag curl is a barbell curl variation where you keep the bar “dragging” up the front of the body instead of curling out and away. By pulling the elbows back behind the body during the curl, you isolate the biceps with almost no help from the front delts — a smart fix when your delts steal work on regular curls.
What it is
The drag curl is a barbell curl where the bar travels up the front of the torso (effectively dragging the body) instead of arcing out and away. To keep the bar against the body, the elbows pull back behind the trunk during the lift. The result: a shorter range but more biceps isolation.

How to drag curl: 5 steps
-
Stand tall
Feet hip-width, **bar in hand at shoulder-width supinated grip.** Arms extended at hips.
-
Brace
**Core tight, shoulders pulled back and down.**
-
Drag the bar up
**Curl the bar up while keeping it in contact with the body.** Elbows travel behind the body.
-
Top of the drag
**Bar reaches lower chest level.** Hold briefly with peak biceps contraction.
-
Reverse the path
**Slowly reverse the drag** as the bar travels back down to full extension.
How it differs from barbell curl
- Bar drags up the body. Travels along the abs/chest instead of arcing forward.
- Elbows go behind the body. Standard curls keep elbows at the sides; drag curls pull them back.
- Front delts disengage. The bar path eliminates anterior deltoid contribution — pure biceps work.
- Shorter range, lighter loads. Expect to use 60-70 % of standard barbell curl weight.
Common mistakes
When to use this variation
Use drag curls when you feel your front delts dominating regular curls, as a biceps isolation finisher, or as a technique drill to learn pure biceps engagement. Program 3 sets of 10-15 reps. Pair after standard curls so the biceps are pre-fatigued and easier to isolate.
FAQ
How high does the bar travel?
Roughly to the lower chest — that’s about as high as the bar can go while staying in contact with the body. Higher than that requires elbows to come forward again.
Straight bar or EZ-bar?
Both work. EZ-bar is easier on the wrists during the elbows-back finishing position.
Will it actually grow my biceps?
Used in rotation with standard curls, yes. It teaches biceps isolation that transfers back to your main lifts.
