As a "boxer", my active tike is over and I do only for the workout by now, it isbsomewhere in between. It is not boring, especially sparring, but then the drills and general carduo is boring in the sense thatvit doesn't need a lot of concentration of the complete brain. You just don't think a lot, meaning while doing it a huge part, of at least my, brain runs on idle.

Thinking of it, I need to go to the gym more. And I need some periodd of general boredom. Lately my brain had close to no occassion to run partially idle and I feel it.

You need boring sports where you don’t need 100% attention to not get hurt. E.g. road cycling on backroads is perfect. Mountain biking… no chance.
