I’ll tell you an easy way to get away with absolutely no exercise: design your life in such a way that moving around is a normal part of it.

Live in a "fifteen minute city." Work someplace that’s either a thirty minute walk or thirty minute bike ride from home. Carry your groceries.

If you get your minimal daily requirement of exercise by just living your normal life, any additional exercise you do is bonus, icing on your cake.

That's a reasonable start for some people but it lacks the resistance training necessary to prevent sarcopenia later in life. Some people get that as part of their job but most of us need to do at least some weight training. Carrying groceries isn't nearly enough.
