What is a repetition?

A repetition — or "rep" — is one complete cycle of an exercise: lowering and lifting the weight once through its full range of motion. A group of reps performed back-to-back is called a set.

Reps vs sets

The two get confused constantly. A rep is one movement. A set is a run of reps done without resting. Programs are written as sets × reps: "3 × 10" means three sets of ten reps. You rest between sets, not between reps. The combination of sets, reps and weight is what determines your training volume and which adaptation you build.

Which rep range trains what

Rep count is a dial. Lower reps with heavier weight bias strength; higher reps with lighter weight bias endurance; the middle builds size. None is "wrong" — it depends on your goal:

1–5 reps85–100% 1RMMaximal strengthHeaviest loads, longest rest (3–5 min).
6–12 reps67–85% 1RMMuscle growth (hypertrophy)The classic size range, 1–2 min rest.
12–20+ reps<67% 1RMMuscular enduranceLighter loads, short rest, higher fatigue.

Whatever the range, the reps only count if they are clean — full range of motion, controlled tempo, close to failure on the last set.

Common questions.

What is a rep in working out?

A rep (repetition) is one full execution of an exercise — for a bench press, lowering the bar to your chest and pressing it back up once. Several reps done in a row make a set.

What is the difference between reps and sets?

A rep is a single movement; a set is a group of reps performed without resting. "3 sets of 10" means 10 reps, rest, 10 more, rest, 10 more — 30 reps in three blocks.

How many reps should I do to build muscle?

About 6–12 reps per set at 67–85% of your 1RM is the classic hypertrophy range, taken close to failure. Growth still happens from roughly 5–30 reps if effort and weekly volume are high enough.

How many reps build strength vs endurance?

Strength is built with heavy loads for low reps (1–5 at 85–100% 1RM); muscular endurance with lighter loads for high reps (12–20+). Hypertrophy sits in the middle.

Should I count partial reps?

Count reps performed through a full, controlled range of motion. Partial or cheated reps reduce the stimulus and make your logged numbers less comparable session to session.
