The term for the maximum amount of weight a person can lift in a single effort is known as one-repetition maximum (1RM). This measurement is commonly used in strength training and weightlifting to assess an individual's maximal strength capacity. Understanding one's 1RM can guide athletes in structuring their training programs, determining appropriate weights for different exercises, and tracking progress over time. Proper testing of 1RM should be conducted with caution to ensure safety and minimize the risk of injury, particularly for novice lifters.
