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.

Description
1 study reviewed
In plain English

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.

Why this might work

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.

  1. Study: 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.
