I've found that few adults think this way. A lot of them avoid exercise and healthy eating because they perceive these as hard and complicated, and they are afraid of doing the work and likely failing anyway. Mainstream advice doesn't help this situation at all.
I get a lot better results at helping people when I show them that health can actually be fun and easy.
I mind doing most chores, and I don't think I'm alone: How many people would choose to do dishes for a family of four if they have a dishwasher to do it for them?
I even like to cook, but most days it is simply a chore and not something I particularly want to do that day.
like most chores, it's not that fun, but the results make it worth it
