Drag Curl Mistakes to Avoid
Curling in a normal arc — the bar must drag UP your body. If it moves away from your torso, it's a regular curl.
Elbows staying at your sides — they need to move BEHIND you. This is what shifts emphasis to the long head.
Going too heavy — the reduced range and strict position mean lighter weights. Use 50-60% of your regular curl.
Expecting full range of motion — the bar only goes to about mid-chest. That's normal. The long head is maximally contracted here.
Drag Curl Muscles Worked
The drag curl targets the long head of the bicep by moving the elbows behind the body, which stretches and loads the long head preferentially. The front deltoid is completely removed from the movement because the bar stays against the body.
Drag Curl FAQ
What's different about the drag curl?
The bar drags up your body instead of arcing away from it. This pulls the elbows behind you, which shifts emphasis to the bicep long head and completely eliminates the front delt. It's a stricter, more targeted curl.
Do drag curls build the bicep peak?
Yes — they target the long head which is responsible for the peak. Pair them with preacher curls (short head) for complete bicep development.
How much weight for drag curls?
50-60% of your regular barbell curl. The restricted range and strict position limit the load. This is about the squeeze, not the weight.
Smith machine drag curls?
Yes — the Smith machine guides the bar path perfectly for drag curls. Some coaches actually prefer the Smith version because the fixed path enforces the drag pattern.
