Set
A group of consecutive repetitions performed without rest.
Updated
A set is a series of repetitions performed consecutively without stopping. After completing a set, you rest before performing another set. The number of sets you perform affects your training volume. Research suggests 10-20 sets per muscle group per week for optimal hypertrophy. Rest between sets typically ranges from 30 seconds to 5 minutes depending on your goals.
What a set means in the gym
A set is a block of reps done one after another, followed by a rest. If a programme says 3 sets of 10 on the leg press, you do ten reps, rest, do ten more, rest, and do a final ten: 30 reps in three sets. Reps are the individual movements and sets are how they are grouped, which is why sets are written first: 3 x 10 means three sets of ten reps, never the other way round.
How many sets per muscle per week
The commonly cited range for muscle growth is roughly 10 to 20 hard sets per muscle per week, counting only sets taken within about three reps of failure. As a worked example for chest: bench press 3 sets and incline dumbbell press 3 sets on Monday, then bench press 3 sets and cable fly 2 sets on Thursday, gives 11. Beginners usually progress well at the lower end or below it. The research shows more volume tends to produce more growth, but recovery is individual, so start lower and add sets only when progress stalls and recovery allows.
Working sets versus warm-up sets
Working sets are the ones the programme counts, done at the prescribed weight and effort. Warm-up sets are lighter sets that build up to them and do not count towards weekly volume. For working sets of 100kg on the squat, a reasonable ramp is the empty bar for 10, then 40kg for 5, 60kg for 3, 80kg for 2 and 90kg for 1. Each step should feel easy; the job is to rehearse the movement, not to tire you before the sets that matter.
Common mistakes
Counting easy sets as hard ones, which flatters the total. Cramming a whole week of volume for one muscle into one session, when the same sets spread over two sessions are generally done with better quality. And resting too little on heavy compound lifts, where two to three minutes or more keeps later sets from falling apart. Adding sets is also not the only way forward; adding weight or reps to the sets you already do is usually the first lever.
Examples
- 3 sets of 10 reps (3x10)
- Performing 12 squats, resting, then doing another 12
- Drop sets reduce weight with each set
