The Claim

In trained females undergoing 12 weeks of resistance training, progressively increasing weekly sets by two or four every two weeks does not result in greater gains in overall lateral thigh muscle thickness compared to maintaining a constant training volume, as no significant differences were found between the progressive and constant volume groups when summing proximal, middle, and distal muscle thickness measurements.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

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
1 study reviewed
In plain English

For women who already lift weights, slowly increasing how many sets they do every couple of weeks doesn’t help them build thicker thigh muscles any more than just keeping their workout the same over 12 weeks.

See the scientific wording

In trained females performing resistance training for 12 weeks, increasing weekly sets by two or four every fortnight does not provide additional benefits for overall lateral thigh muscle thickness compared to constant volume, as no significant differences were observed between progressive and constant volume groups in the sum of proximal, middle, and distal muscle thickness measurements.

What the research says

1 study
  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 looked at whether gradually increasing leg workout volume helps build more thigh muscle in women, and found it didn’t make a difference for overall thigh muscle thickness compared to keeping the same workout volume.
