What is 1RM?

1RM, or one-repetition maximum, refers to the maximum amount of weight that a person can lift for a single repetition of a given exercise. It is a common measure used in strength training to assess an individual's maximal strength and track progress over time. 1RM is often determined through testing or calculated using submaximal lifts and specific equations. Understanding one's 1RM helps in designing effective training programs tailored to individual strength levels.
