That sounds like a self-discipline problem.

What’s wrong with incorporating exercise into one’s lifestyle, without dedicated exercise time? It’s convenient and sustainable. Sure, it’s not as good as dedicated exercise time in terms of the adaptations one would get, but it’s much better than the adaptations they’d get on their couch.

Nothing is wrong with that - it's the issue of attempting to impose it on others which is objectionable.

point me to where they tried to "impose" this on others...

And the walk to work is a self-discipline solution!

You wierdos want everyone to have to micromanage our own mental health like we're islands. Humans are social creatures with social rituals for a reason. We go mad without them. People shouldn't have to force themselves to do everything without any social support. (and i go to the gym 4 times a week with my own discipline so no im not incapable i just don't want to have to do that about everything ever)
