I think most people would be shocked by how little time actually working out it takes to get significantly stronger and to feel better — if you work out correctly.

In the army I worked out so much (not of my own choice) that it was counterproductive. You don’t need that much.

I’ve only been working out heavily again for a few months now, and I’m already 20-40% stronger than I was, depending on exercise and if you measure weight or endurance (both matter).

In a year, most people can double their strength and more than double their endurance, all with around 45 minutes three times a week. More than that, say up to an hour a day six times a week, will still benefit you but not comparatively as much.

Not that much time spent can really improve your life a great deal.
