Exercise & Depression: A Game Changer?

I have long advocated that exercise can help reduce symptoms of depression in many adults, especially when done regularly at light to moderate intensity. An updated Cochrane review, just published, further supports my position. It suggests that exercise is generally safe and accessible and can be part of a broader plan to support mood, brain health, and overall well‑being.

About This New Study

A team of researchers led by Professor Andrew Clegg and colleagues updated a major Cochrane Review titled “Exercise for depression” (Cochrane Database of Systematic Reviews, 2026; CD004366.pub7). They analyzed dozens of randomized controlled trials where adults with depression were assigned to exercise programs, usual care, talking therapy, antidepressant medications, or control conditions.

The authors found that structured exercise programs produced a moderate improvement in depressive symptoms compared with no treatment or control activities. When exercise was compared directly with psychological therapy, the benefits were similar in size, though the evidence base is still limited for some comparisons and long‑term effects.

What Kind of Exercise Helped?

The review looked at many forms of physical activity, including:

• Walking programs and aerobic exercise classes

• Mixed routines that combine strength, balance, and endurance work

• Supervised group exercise sessions in community or clinical settings

Interestingly, across studies, light to moderate intensity activity tended to be more effective than very vigorous exercise, and completing 13-36 exercise sessions was linked with greater improvements in mood. No single type of exercise clearly “won,” but mixed programs and resistance (strength) training often showed somewhat stronger effects than aerobic exercise alone.

Side effects were uncommon and mostly mild, such as occasional muscle or joint discomfort, while antidepressant groups sometimes reported medication‑related problems like fatigue or stomach upset.

What this Means for BrainSavers Members

As a neurologist and founder of BrainSavers, I have long emphasized that regular, enjoyable movement is one of the most powerful tools for protecting both brain and mood as we age. This new Cochrane review supports that message: exercise is not just “good for you” in general; it can play a meaningful role in easing depression symptoms for many adults.

For we seniors, this is especially important. Depression in later life can worsen memory, increase fall risk, and reduce independence -- but it is not an inevitable part of aging. Structured, social exercise, like the brain‑body fitness sessions in the BrainSavers program, can help improve mood, thinking skills, sleep, and confidence at the same time.

How BrainSavers Puts the Science Into Action

BrainSavers classes already include several elements highlighted in this research:

• Regular sessions: Members attend scheduled classes multiple times per week, helping them reach and exceed the 13–36‑session “zone” associated with better mood outcomes.

• Mixed brain+body routines: Sessions blend aerobic movement, strength training, balance work, and cognitive challenges, which aligns with evidence that varied and resistance‑based programs may be especially helpful.

• Social support and supervision: Instructors guide participants to work at light to moderate intensity, adjust for medical conditions, and exercise safely as part of a supportive community, which improves both adherence and enjoyment.

For members who are feeling down, less motivated, or worried about memory, the message from this new review is encouraging: starting where you are, and moving at a comfortable pace, can still make a difference. Even short, regular bouts of walking, chair exercises, or gentle strength work, especially when combined with BrainSavers’ mental activities and lifestyle lessons, may help lift mood and support long‑term brain health.

The takeaway: You do not have to “feel good” to get started—but getting started is often one of the best ways to begin feeling better.
