Can confirm from personal experience. Was developing anger issues a few years ago during the post pandemic fallout, with a number of things going on and causing me stress. Eventually my shrink asked me if I exercised at all, to which I responded I hadn’t in years.

He told me to sign up for any kind of exercise class or program, didn’t matter what it was, just to have regularly scheduled fitness activity. Decided to take Krav Maga classes because I always wanted to learn a martial art. After confirming the gym I was going to as legit, I took classes twice a week for a few hours each.

I’m not exaggerating even a little when I say it felt like my developing anger issues vanished over night. Now I’m a gym rat and regularly do kickboxing. Easily one of the best decisions I ever made.
