Kovacevic A, et al.
Evidence is still building up
Summary
A 16-week RCT examining the effects of resistance training on sleep quality (Pittsburgh Sleep Quality Index: PSQI), sleep duration, and subjective fatigue. The training group showed significant improvement in sleep quality scores and reduced subjective fatigue. Effects were most pronounced in participants with pre-existing sleep difficulties.
Key findings
- 1
16 weeks of resistance training significantly improved PSQI (sleep quality) scores
- 2
Subjective fatigue was reduced with reports of improved daytime functioning
- 3
Greatest improvement in those with pre-existing sleep difficulties
- 4
Evening training showed minimal impact on sleep onset, within individual variation range

JAMA Psychiatry, 2018
A meta-analysis evaluating the effects of resistance training on depressive symptoms, anxiety, and general mental health. Analyzing 33 RCTs, resistance training was found to significantly reduce symptoms of depression and anxiety. Effect sizes were medium to large (d = 0.66), suggesting mental health benefits comparable to or exceeding aerobic exercise.
