e1RM (estimated one-repetition maximum)

E1RM, or estimated one-repetition maximum, refers to the maximum amount of weight a person can lift for one complete repetition of an exercise. It is often estimated based on how much weight someone can lift for multiple repetitions. For example, if you can lift a certain weight for 5 reps, there are formulas to estimate how much you could lift for just one repetition. This measure is useful for assessing strength levels, planning workout routines, and tracking progress in strength training. It helps individuals understand their lifting capacity without the need to attempt a maximum lift, which can be risky.
