Drag Curl

Move · Resistance Training · Movement, Typed Supps

In an ordinary curl the weight gets easy near the top; dragging the bar up the body keeps it hard the whole way.

Stage by stage

Set-up (Elbows driven backwards): The humerus moves into extension instead of flexion, removing the anterior deltoid's usual assistance at the top.
During the rep (Bar stays on the torso): Contact with the body keeps the path honest — a bar drifting forward means the shoulders have started helping.
Near the top (Moment arm preserved): A standard curl loses its resistance arm as the forearm nears vertical; here the travelling elbow keeps tension on.
Weeks later (Lower load, same demand): Usable weight falls because helper muscles were removed, not because the biceps is doing less work.

Muscles trained

Primary: biceps
Secondary: rear shoulders

Intensity

3.5 METs (Resistance (weight) training, multiple exercises, 8-15 repetitions at varied resistance).

Time to effect

Weeks: The elbows-back bar path feels awkward at first and often requires lighter loads than your regular curl while you groove the new movement pattern.
Months: With the front delts taken out of the equation, consistent drag curls can add biceps size and a fuller look to the upper arm that a standard curl, which recruits some front-shoulder assistance, does not train quite the same way.

Common myth

"The drag curl is just a standard curl done with sloppy form." In reality: The dragging bar path and elbows-back position are deliberate technique choices, not a form breakdown - they change the joint angle and shoulder involvement on purpose, shifting more isolated tension onto the biceps.
