Example: Lowering and pressing the weight once during a bench press counts as one rep.
Set

Example: 3 sets of 10 reps means you perform 10 reps, rest, and repeat that two more times.
Volume

Example: Perform push-ups until you cannot complete another rep with good form.
RPE (Rate of Perceived Exertion)
A scale, usually from 1 to 10, that measures how hard a set feels.
