The Claim

In trained females undergoing 12 weeks of resistance training, progressively increasing weekly training volume every two weeks—specifically by four sets—leads to greater increases in vastus lateralis cross-sectional area compared to maintaining a constant volume of 22 sets per week, suggesting that volume progression enhances quadriceps muscle growth.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

If women who already work out increase their leg training gradually over 12 weeks, they might build more muscle in their quads than if they stick to the same number of sets the whole time—especially if they add four sets every two weeks.

See the scientific wording

In trained females undergoing 12 weeks of resistance training, progressively increasing weekly sets every two weeks results in greater increases in vastus lateralis cross-sectional area compared to maintaining a constant volume of 22 sets per week, particularly when progressing by four sets, indicating that volume progression may enhance muscle growth in the quadriceps.

  1. Study: Does increasing the resistance-training volume lead to greater gains? The effects of weekly set progressions on muscular adaptations in females

    The study found that women who gradually increased their leg workout volume by four sets every two weeks gained more muscle in their quadriceps than those who did the same amount each week.
