The one-repetition maximum (1RM) for the bench press is a widely utilized metric in resistance training and sports science for assessing upper body maximal strength.

​

Defined as the maximum load that an individual can lift for one complete repetition with proper form, the 1RM is typically measured in either kilograms (kg) or pounds (lbs). It serves as a fundamental benchmark for evaluating muscular strength, prescribing training intensities, and monitoring strength development over time. Accurately determining the 1RM allows for the individualized adjustment of training loads according to specific performance goals or rehabilitation protocols.
