1RM: One repetition maximum. The maximum amount of weight a trainee can lift for one repetition. In strength training, the 1RM is used as a primary means of measuring intensity, which is expressed as a percentage of the lifter's maximum ability or one rep maximum. If a strength trainee's 1RM for the back squat is 300lbs and he is squatting with 255lbs on the bar, then his intensity is given as 85%, as 255 is 85% of his 1RM.
