curl bro

Definition

A gym-goer who disproportionately emphasizes arm training over compound movements and leg day, typically found monopolizing the dumbbell rack while their chicken legs tell their own story.

Example Usage

That curl bro has done six bicep exercises this session but I've never seen him near the squat rack.

Origin

Gym culture slang from the 2000s

Fun Fact

The term reflects the stereotype of vanity training, though research shows balanced programming produces better overall arm development anyway, making curl bros inefficient at their own goal.
