Series (Sets)

A series (or set) is a group of consecutive reps without rest. The basic unit of training programming.

Series - The basic training unit

Definition

A series (or "set") is a group of consecutive reps performed without rest. After the series ends, you take a defined rest before the next one. It's the basic structural unit of any training program.

💡 A program is built on the trio: number of sets × number of reps × load. Total volume = sets × reps × load.

How many sets per muscle group?

The current scientific consensus on weekly volume:

  • Beginner: 8-12 sets/muscle/week
  • Intermediate: 12-18 sets/muscle/week
  • Advanced: 16-22 sets/muscle/week
  • Maximum sustainable: 25-30 sets (rare profile)

⚠️ Counting sets: only count the working sets close to failure (RIR 0-3). Warm-up sets don't count.


The different types of series

  • Straight set: same load, same reps, fixed rest
  • Pyramid: load increases, reps decrease (e.g. 12-10-8-6)
  • Reverse pyramid: heaviest set first, then lighter
  • Cluster set: small reps with mini-rests in the same set
  • Working set: maximum effort set
  • Warm-up set: light, doesn't count as volume

Common mistakes

  • ❌ Counting warm-up sets in working volume
  • ❌ Stopping too far from failure (RIR 5+) systematically
  • ❌ Always going to absolute failure on every set
  • ❌ Doing too many sets without recovery → overtraining
  • ❌ Doing too few sets thinking it's "smart programming"

Key takeaways

The series is the basic unit of all training. Master rep ranges, weekly volume, and rest. Volume is what drives muscle growth — but only sustainable volume. Track and adjust.
