The Claim
The relationship between resistance training volume and muscle hypertrophy in trained individuals is inconsistent across studies, with some evidence indicating no inherent benefit from higher volumes compared to lower volumes.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Studies show mixed results on whether doing more resistance training sets leads to more muscle growth in people who already train regularly. Some findings suggest that increasing the number of sets doesn't necessarily lead to greater muscle gains.
See the scientific wording
The relationship between resistance training volume and muscle hypertrophy in trained individuals remains inconsistent across studies, with some evidence suggesting no inherent benefit from higher volumes compared to lower volumes.
When muscles are trained regularly, the signals that tell them to grow become fully activated and can't get any stronger, so doing more workouts doesn't make them grow any bigger.
What the research says
1 studyStudy: The Importance of Previous Resistance Training Volume on Muscle Growth in Trained Individuals
For people who already lift weights regularly, doing more sets doesn’t always mean more muscle growth—some studies say yes, others say no. This study confirms that the results are mixed and not clear-cut.
