Some of us are more intrinsically motivated to work out, more inclined and apt to stay healthy and in shape and disciplined to a diet that allows them to be the best version of themselves. More of us, however, are not that person; we're jealous and more than a little resentful of that person, if we're honest, provided that we've seen one of them in the real world. For the vast majority of us, exercise is a slog, and there's an entire industry that's cropped up to make it easier and more convenient for us to do something that we still nevertheless don't want to do. In recent years, the tricks involved in getting us on these machines have gotten even more advanced: TVs built in, music playing, even immersive experiences that simulate an outdoor bike ride. It's enough to make you consider exercise as near-entertainment, which is rather the point.
