Careful with this. I was “self-medicating” my ADHD with exercise for years simply thinking I just liked exercise and not ever realizing that I had worked up to 25-30 hours a week just to function. Exercise absolutely does 100% work but meds that raise your baseline so you don’t have to exercise is a much healthier relationship with it.

There are a lot of habits that ADHD people fall into to “stim.” Whether or not it’s a healthy way of managing it is up to the person.
