It depends on the activity. I can't exercise or clean unless I'm watching TV or YouTube. But I've tried the whole exercise while gaming thing, and it doesn't work for me at all. Listening to audiobooks while doing literally anything else is also impossible.
I know a dude who did this with a standing desk and an exercise bike when WOW was huge and he put on 20kg in a year.
Playing wow while cycling is a level of multitasking even adhd people would struggle to pull off.
Having ADHD is pretty awful for multitasking, so that's not saying much.
