Thanks for your extensive input.

In my article on ADHD and exercise from two years ago https://medium.com/invisible-illness/working-out-and-working-off-symptoms-of-adhd-d2a87ec0452

I spent more time on how to increase motivation and organization in order to establish an exercise regimen, and most of those tips would also apply to depression.

Some of the studies both on mood and on ADHD with exercise have looked at balance as well as tai chi type exercise and have found positive results.
