Rep
Repetition
Short definition
Repetition — a single performance of an exercise within a set.
Full definition
A rep is one complete movement (lowering + lifting). Reps per set depend on the goal: 1–5 for strength, 6–12 for hypertrophy, 15+ for endurance. In isometrics a 'rep' is one static hold of a given duration.
Examples
3 sets of 8 reps at RPE 8.
