Strength Training and Mental Health Benefits
A recent study published in the journal *Psychological Medicine* highlights the potential benefits of strength training in alleviating symptoms of depression. Conducted by researchers at the University of Limerick, the study involved 62 young adults, some of whom had subclinical generalized anxiety disorder and/or major depressive disorder. Participants were divided into two groups: one engaged in an eight-week resistance training program, while the other served as a waitlist control, participating in 30 minutes of quiet rest. The findings indicated that both groups experienced improvements in mood after just one session, with strength training showing a positive impact on depressive symptoms.
Mechanisms Behind the Benefits
Darragh O'Sullivan, PhD, the lead author of the study, suggests that the antidepressant effects of both aerobic and resistance training may share common mechanisms. These include improvements in brain structure and function, increased blood flow to the brain, and reduced inflammation. Notably, resistance training may enhance levels of insulin-like growth factor-1, a hormone crucial for neuronal growth and repair in mood-regulating brain regions. The study also points to the psychological benefits of strength training, such as increased feelings of accomplishment and empowerment.
Recommendations for Implementation
For individuals new to exercise, O'Sullivan recommends starting with manageable strength training routines, such as two sets of eight to twelve repetitions targeting major muscle groups. The key is to ensure that the final repetitions are challenging. Albert Matheny, co-founder of SoHo Strength Lab, emphasizes the importance of proper form and gradual progression in weight to maximize benefits and minimize injury risk.
Criticism and Limitations
While the study provides valuable insights, it does not directly compare strength training with aerobic exercises, which have more established evidence for improving mood. Critics argue that more comprehensive research is needed to fully understand the unique contributions of resistance training to mental health.
Broader Implications for Mental Health
The findings from this study contribute to a growing body of literature suggesting that physical activity, including both aerobic and resistance training, plays a vital role in mental health. Regular exercise is increasingly recognized as a non-pharmacological intervention that can complement traditional treatments for depression and anxiety.

- “We believe that the antidepressant effects of aerobic and resistance training largely have shared mechanisms,” — Darragh O'Sullivan, PhD, University of Limerick
- “You can end up feeling strong and feeling like you can do things that you weren’t previously able to do,” — Thea Gallagher, PsyD, NYU Langone Health
- “Research studies have shown that a single session of walking, running, cycling, and resistance exercise can all individually reduce depressed mood state,” — Darragh O'Sullivan, PhD
Conclusion
Strength training emerges as a promising avenue for enhancing mental health, particularly in young adults experiencing depressive symptoms. As research continues to evolve, integrating resistance training into mental health strategies may offer a multifaceted approach to improving overall well-being.
