Walking is underrated. I've intentionally walked at least 3 miles every day (not without fail!), at top speed, in addition to whatever else is part of daily life. I don't intentionally do any other exercise (though apparently I'm strong enough to get asked to move things). My resting heart rate (in my 30s) is 48 bpm. Forty-eight! (As measured on multiple occasions by genuine hospital equipment that I happened to be using in the course of testing/working on it.) For someone who used to be a fat guy, that seems incredible. And yet there it is.
