Most people think of lifting as something you do for your muscles and bones, and of running or walking as the exercise that helps your mood. That split does not hold up. Randomized trials show that resistance training reduces symptoms of depression and anxiety, including in adults over 60 with diagnosed depression. It is not a cure and not a replacement for care, but after 50 it is a habit that works on your strength, your independence, and how you feel at the same time.
What Does the Research Actually Show?
The best single summary for depression is a meta-analysis of 33 randomized trials with 1,877 participants (Gordon et al., 2018, JAMA Psychiatry, PMID 29800984). Resistance training produced a moderate reduction in depressive symptoms compared with control conditions. The average participant age was 52, and the effect held regardless of age, sex, or health status. Trials where participants started with mild to moderate depression saw larger reductions than trials where they did not.
A companion meta-analysis looked at anxiety across 16 studies and 922 participants (Gordon et al., 2017, Sports Medicine, PMID 28819746). Resistance training reduced anxiety symptoms, with a smaller effect than for depression. The effect was larger in healthy participants than in people with a physical or mental illness, though it was still significant in both groups.
The largest recent review compared exercise types head to head. A network meta-analysis of 218 studies and 14,170 participants with depression found that walking or jogging, yoga, and strength training all reduced symptoms compared with active controls (Noetel et al., 2024, BMJ, PMID 38355154). Strength training and yoga were also the forms people were most likely to stick with. The authors rated their confidence in these estimates as low for walking or jogging and very low for the other types, so future trials could still shift the picture.
Does It Work for People Over 60?
The direct evidence in older adults is smaller but encouraging. In a 10-week trial, 32 adults ages 60 to 84 with major or minor depression or dysthymia did supervised progressive resistance training three times a week or attended an attention-control program (Singh et al., 1997, Journals of Gerontology: Series A, PMID 9008666). Depression scores dropped significantly more in the lifting group, strength rose by about a third, and vitality, social functioning, and bodily pain improved as well. Median attendance was 95%.
The same research group then tested whether intensity mattered. Sixty adults over 60 with major or minor depression were randomized to high-intensity training at 80% of their maximum, low-intensity training at 20% of their maximum, or standard care from their general practitioner, three days a week for 8 weeks (Singh et al., 2005, Journals of Gerontology: Series A, PMID 15983181). A 50% drop in depression scores was reached by 61% of the high-intensity group, 29% of the low-intensity group, and 21% of the usual-care group.
One honest caveat: in the 2024 network meta-analysis, strength training appeared more effective in studies with younger participants, while yoga appeared more effective in older ones. That comparison was made at the level of studies, not individual people, and the authors flagged real uncertainty. It does not mean lifting stops working after 50. It does mean the direct evidence in older adults comes from a few small trials, and it is fair to say so.
Why Might Lifting Help Your Mood?
The research does not pin down a single mechanism, and you should be wary of anyone who claims it does. Two findings from the trials above are worth knowing.
First, effort seems to matter. In the 1997 trial, training intensity independently predicted how much depression scores fell, and in the 2005 trial the heavy group did far better than the light group. The 2024 review also found that benefits tended to rise with the intensity prescribed.
Second, getting stronger is not the whole story. The 2018 meta-analysis found that the size of the strength gain was not linked to the size of the mood benefit. You do not need to hit a number on the bar to feel the effect. Working hard for your level, and doing it regularly, is the more useful target. We cover the brain side of this in more depth in how strength training changes your brain after 50.
Is Strength Training a Replacement for Treatment?
No. None of the studies above tested dropping therapy or medication in favor of lifting. If you are already being treated for depression or anxiety, think of training as something that works alongside that care, and do not change or stop a medication without talking to the clinician who prescribed it.
If your mood has been low for more than a couple of weeks, if you have lost interest in things you usually enjoy, or if worry is getting in the way of sleep or daily life, talk with your doctor. That conversation comes first. If you are having thoughts of harming yourself, call or text 988 to reach the Suicide & Crisis Lifeline.
How to Use Strength Training for Your Mood This Week
The trials used simple, repeatable programs. You can build the same structure:
- Train two to three days a week. The older-adult trials used three supervised sessions a week for 8 to 10 weeks. Two is a reasonable starting point if you are new.
- Use the big movements. Squat or sit-to-stand, hinge, push, pull, and carry. Six to eight exercises per session is plenty.
- Work hard for your level. Aim for sets of 8 to 12 reps where the last two or three are genuinely difficult. The heavier group in the 2005 trial trained at 80% of their maximum, so build toward challenging loads over several weeks rather than staying light forever.
- Give it 8 to 10 weeks. That is how long the trials ran before measuring results. Judge it by how your weeks feel, not by one session.
- Protect consistency over intensity on bad days. On a low day, a shorter session at a moderate effort still counts. Missing a session is normal. Quitting because you missed one is the thing to avoid, a point we unpack in why consistency matters more than intensity after 50.
- Get some supervision if you can. Both older-adult trials were supervised, and supervision helps with both technique and showing up.

Key Takeaways
- A meta-analysis of 33 randomized trials found that resistance training produced a moderate reduction in depressive symptoms, with the effect holding across age, sex, and health status.
- A meta-analysis of 16 studies found that resistance training reduced anxiety symptoms, with a smaller effect than for depression and a larger effect in healthy participants.
- A 2024 network meta-analysis of 218 studies found that strength training, walking or jogging, and yoga all reduced depression, though the authors rated confidence in those estimates as low to very low.
- In small trials of adults over 60 with depression, supervised resistance training lowered depression scores more than control conditions, and high-intensity training outperformed low-intensity training and usual care.
- Effort appears to matter more than the size of your strength gains, so working hard for your level and staying consistent is the goal.
- Strength training works alongside treatment, not instead of it, and anyone with persistent low mood or anxiety should talk with their doctor before making changes to their care.
