The Claim

In resistance-trained males undergoing six weeks of moderate caloric restriction, performing 20 sets of resistance training per week has no different effect on subjective sleep quality and mood compared to performing 12 sets per week.

Description
1 study reviewed
In plain English

Among men who regularly lift weights, reducing calorie intake for six weeks does not worsen sleep quality or mood whether they do 12 or 20 sets of resistance exercises per week.

See the scientific wording

Resistance-trained males maintain subjective sleep quality and mood during six weeks of moderate caloric restriction regardless of whether they perform 12 or 20 sets of resistance training per week, indicating that higher training volume does not negatively impact psychological well-being under these conditions.

Why this might work

When a trained person cuts calories, their brain maintains steady levels of chemicals that regulate sleep and mood, and this stability keeps their sleep and feelings from getting worse, no matter how many weightlifting sets they do.

  1. Study: Resistance training volume does not influence lean mass preservation during energy restriction in trained males

    When men who lift weights cut calories, doing more or fewer sets per week didn’t make them sleep worse or feel more down — so more lifting doesn’t hurt your mood or sleep.
