One-Rep Max (1RM)

Beginner ⚽ Sports / Fitness

Definition

The heaviest weight you can lift for a single repetition—the ultimate flex that makes gym bros respect you for about 3 seconds.

Example Usage

My bench press one-rep max is 315 pounds.

Origin

Fundamental strength testing metric, used since the advent of weightlifting sports

Fun Fact

Most trainees never need to test their actual 1RM; estimates from multiple reps are safer and nearly as accurate.
