Definition
The heaviest weight you can lift exactly once before your body sends you a strongly-worded cease-and-desist letter. It's the gym's version of a high score, and people will exaggerate theirs with the same confidence as fishermen describing the one that got away.
Example Usage
"He claims his one rep max on bench is 315 pounds, which is interesting because I've never actually seen him bench more than 225, but who am I to question gym mythology."
