Exercise for depression: what actually helped me
When I was going through the worst of my burnout and depression, the LAST thing I wanted to do was exercise. But my therapist basically prescribed it and I'm glad I listened. Here's what worked for me specifically for mood, not for getting jacked:
Walking. Yeah, boring. But 30 minutes outside every morning was probably more effective than anything else I did. Something about sunlight + movement + being outside. It's not fancy but it works.
Heavy resistance training. 2-3x per week. Something about picking up heavy things and putting them down when you're angry or sad is incredibly therapeutic. Plus the confidence boost from getting stronger is real.
Yoga. And yes I know — a football coach doing yoga. My wife laughed too. But breathing exercises + body awareness + forced stillness was exactly what my overstimulated nervous system needed. I do 20 minutes twice a week now.
What did NOT help: intense HIIT when I was already stressed. My cortisol was through the roof and adding more stress on top of stress made everything worse. Learned that one the hard way. Marcus can probably explain the cortisol thing better than me.
Jake nailed it on the cortisol piece. When you're already in chronic stress, your cortisol is elevated basically 24/7. Adding high-intensity training on top of that is like pouring gasoline on a fire. Your body doesn't distinguish between "good stress" from exercise and "bad stress" from life — it's all just cortisol.
For anyone in a high-stress or depressive state:
- Low-to-moderate intensity: walking, easy cycling, swimming, yoga — these LOWER cortisol
- Heavy but brief resistance training: heavy compound lifts for 30-45 min — this creates a short cortisol spike that actually helps regulate the system
- Avoid: hour-long HIIT sessions, CrossFit-style WODs, anything that leaves you completely wrecked
Once your stress is managed and your sleep is dialed in, you can add intensity. But build the foundation first.
the walking thing is legit. my therapist told me the same thing. I walk 20 minutes every morning now before work and on the days I skip it I can absolutely tell the difference. my coworkers can tell too lol
also +1 on yoga. I do it in my living room with a youtube video because theres no way im going to a yoga studio surrounded by flexible women in lululemon. maybe someday but not yet haha
From a clinical perspective, the evidence for exercise as an intervention for depression is incredibly strong. A 2023 meta-analysis in the BMJ found that exercise was as effective as SSRIs for mild-to-moderate depression. Not "almost as effective" — AS effective.
The morning walk specifically hits multiple pathways: circadian rhythm regulation from sunlight exposure, serotonin production, BDNF release (brain-derived neurotrophic factor, which is basically fertilizer for your brain), and the simple dopamine reward of completing a task first thing in the morning.
I always tell my patients: medication is great. Therapy is great. Exercise is the thing that makes both of them work better.
