My current trick for aerobic exercises is... Beat Saber. It's a rhythm game for VR headsets, in which you use your controllers as light sabers and have to cut apart cubes and avoid obstacles, all to the beat of music. At higher difficulty levels it gets pretty intense, so it works great as an exercise, and it's also <i>fun</i>. You don't even notice when you start sweating from exertion.<p>My wife and I talked a lot about getting a dancing mat, which was my college friend's go-to exercise technique (he ended up going semi-pro and winning some awards in StepMania competitions), but dancing mats - especially hard ones - make a lot of noise, making them unsuitable for use in an apartment in a block of flats. Dancing games have similar benefits - exercising becomes <i>fun</i>, and there's built-in progression to guide you. But after Oculus Quest - a standalone, untethered VR headset - came out, we decided to go the Beat Saber route. Waving hands doesn't make the noise stepping does, and untethered headset is even more portable than the dancing mat.
