Research Questions Whether Three Sets Are Needed for Hypertrophy
Scientists have studied how many sets of an exercise people should do.
Some workouts use a small number of sets taken close to failure, while others use three or more sets.
Muscle growth is called hypertrophy.
Many people believe that three sets are necessary for the best results.
However, a widely cited research paper did not support that belief.
It found that one set and several sets often produced similar strength and muscle-growth improvements.
This was true in studies lasting four to 25 weeks.
The best choice may depend on a person’s fitness goals and experience.
Research compares single-set training with multiple-set approaches for strength and muscle growth.
The article highlights a comparison between two sets taken to failure and three or more sets.
Hypertrophy is the gym term for muscle growth from resistance exercise.
A widely cited research paper found no significant difference between single and multiple sets in studies lasting four to 25 weeks.
The evidence challenges the belief that at least three sets are always required for optimal results.
- Who
- Researchers studying resistance training and people who exercise.
- What
- The evidence compares single-set and multiple-set training for strength and muscle growth.
- Where
- When
- The cited research examined training periods lasting four to 25 weeks; its paper was published nearly 20 years ago.
- Why
- To determine whether doing three or more sets is necessary for optimal strength and muscle growth.
Key facts
- Main comparison
- Single-set versus multiple-set resistance training

Strength training. Single versus multiple sets research paper
A research paper cited in the article for its review of single-set and multiple-set strength training.
“There is a prevalent belief that at least three sets of each exercise are required to elicit optimal increase in strength and hypertrophy.”
