Walking on two legs. We hominids have been doing it for the past few million years. Consequently, it’s one of the things our species is best known for. For most of human history, walking and running were the only means of getting from A to B. These days, that’s no longer the case for most of us. That’s too bad because walking—particularly at a brisk pace—is an innate way in which we can burn calories and torch belly fat. It requires little in the way of equipment, it can be done more or less anywhere and it’s less likely to stress the joints in the way that running can. And sure, we’d all like to look like Mark Langowski and be on the cover of Eat This, Not That! For Abs with a shredded six-pack, but just getting off our butts and using our two feet is a solid start.
