AMRAP (As Many Reps As Possible)
AMRAP (As Many Reps As Possible) is a set in which the lifter performs as many quality reps as possible at a prescribed weight, typically used as the final working set in strength programs.
AMRAP sets serve two purposes: they generate hypertrophy stimulus from accumulated reps near failure, and they provide a real-world data point about strength progression. In Wendler's 5/3/1, the third working set of weeks 1-3 is an AMRAP at 85%, 90%, and 95% TM respectively.
Programmers track AMRAP rep counts over multiple cycles to gauge progress without re-testing 1RM. If a lifter is hitting more reps on the same percentage cycle-over-cycle, strength is increasing regardless of when the 1RM is next tested directly.

Wendler 5/3/1
Wendler 5/3/1 is a strength training program created by Jim Wendler in 2008 that uses 4-week waves of percentage-based work on the four main barbell lifts (bench, squat, deadlift, overhead press), with each lift trained once per week.
Training Max (TM)
Training Max is a working percentage (typically 85-90%) of true 1RM used as the base for percentage-based training prescriptions.
RPE (Rating of Perceived Exertion)
RPE (Rating of Perceived Exertion) is a 1-10 scale that describes how hard a working set was relative to true failure, where 10 means no more reps were possible and 8 means 2 reps in reserve.
