HN suffers from a peculiar obsession with theory and optimization. There's no secret to aerobic exercise: go get your heart rate mildly elevated for a while. Do whatever activity you can stand making part of your regular life, and stick with it. Do it long enough and you'll lose weight to boot. This is a simple truth. Things get complicated at the fringes, or if you want to actually train vs just get fit, but most of HN is not a fringe case unable to benefit from basic exercise. They just pretend to be to ignore that simple truth.
