TL;DR: Being active at work isn't necessarily the same as intentional exercise. New research suggests leisure-time activity may offer health benefits that physically demanding work doesn't.
If you spend eight hours walking, lifting, carrying or standing at work, hitting the gym afterward might sound a little ridiculous.
You moved all day. Surely that counts as exercise, right?
It counts as physical activity, but new research suggests our bodies may respond differently to movement we do at work and movement we choose to do in our free time.
In fact, a large new review found a surprising difference between leisure-time exercise and physical activity on the job, especially when researchers looked at dementia risk.
So, if you already have a physically demanding job, do you still need to exercise?
