What does this rating mean?
Multiple consistent meta-analyses or a position stand. Sufficient basis for a fixed choice in the coaching.
Findings
Resistance training is associated with a meaningful reduction in depressive symptoms in participants of controlled trials, regardless of age, sex, health status or training volume — though this remains an associative link and is not a standalone, proven treatment.
Who this applies to
Adults, both healthy and with a physical or mental illness.
Size of the research
33 randomised trials with a combined 1877 participants.
What to keep in mind
Results varied widely between trials. Trials with blinded allocation or assessment found smaller effects.
Practical conclusion for REZA
As part of a broader approach, resistance training can contribute to well-being, but it is not a substitute for treatment of depressive symptoms.

Methodology
Meta-analysis and meta-regression of randomised trials
Limitations
Included studies varied in quality and clinically diagnosed participants were underrepresented; resistance training does not replace professional mental-health care.
