Anecdata. I work out pretty heavily - 5 sets of pull ups at a time, squats, core muscle exercises for 40 minutes (my disks tend to fall out and it prevents that). I used to run about once every 2 days, but now instead I'm doing about 30 minutes of hip exercises so my joints don't ache. I also have heavy depression and anxiety. And exercise is not enough to lift my mood. I guess I would feel worse if I didn't. I do it out of habit and because on a rational level I know it's beneficial in the long run.
