the pump

Definition

The temporary muscle swelling and tightness from blood pooling during resistance training, creating a satisfying fullness that Arnold Schwarzenegger famously compared to orgasm. Yes, really.

Example Usage

That high-rep arm workout gave me the sickest pump—I could barely bend my elbows.

Origin

Bodybuilding terminology, famously described by Arnold Schwarzenegger in the 1977 documentary 'Pumping Iron.'

Fun Fact

The pump is caused by blood plasma filling the muscle cells, creating temporary hypertrophy that disappears within hours.
