Researchers evaluated evidence from 73 randomized controlled trials that included about 5,000 people with depression.

Dr. Steven Matika of Inspira Health says the new review confirms just how effective exercise can be.

Exercise mirrors some of the effects of medication and can boost feel-good compounds in the brain, including serotonin, dopamine, and endorphins.

The review finds light to moderate activity, including a brisk walk, can be just as effective as more intense exercise.

And they found the combination of aerobic exercise and strength training appears to be more effective than cardio alone.
