Drag the bar up your torso for a savage peak contraction.
Keep the bar grazing your body and pull the elbows back, not up.
By pulling the elbows back and dragging the bar up your torso, you strip the front delts out of the movement, which is where most curls quietly leak tension. The biceps end up doing all the work into a hard shortened position, giving a peak contraction a normal curl path never quite reaches. It slots in as a strict finishing move rather than a heavy ego lift.
In a regular curl the bar swings out in an arc and the shoulders sneak into the lift. In a drag curl the bar stays glued to your body and the elbows travel backwards, keeping the biceps isolated and the contraction harder at the top.
Because you have removed momentum and shoulder assistance, the two things that inflate normal curl numbers. Less weight moving through a stricter path is the entire point, so drop the load and chase the squeeze.
Only as high as you can drag it while it stays in contact with your torso, usually somewhere around the lower chest. The moment it drifts away from your body it has become a regular curl.
