An anecdote. I have a friend who used to walk everywhere in the city. They were always overweight but healthy. Flash forward to several years later. They are in the thick of a PhD program. The last couple years they have gained considerable weight. Lots of inactivity (sitting in a room all day) coupled with lack of sleep and not the best eating habits. And I recently learned that they have trouble walking, say, a parking lot distance. And their knees will start to hurt on a scale of 6 on a 10 scale if they do too much walking.
Too little exercise if accompanied by other less healthy life actions (sleep deprivation, less healthy diet) can rob you of one thing you might take for granted: mobility or the ability to walk across a long parking lot without strain.
There is no one size fits all recipe for how much physical activity. Your health is ultimately your responsibility.
