When I was in the Marine Corps, I developed a "gaming workout routine" to keep in shape and still have time to play video games where I didn't even have to leave the desk, and it worked wonders. I have always thought it would be awesome to somehow make it a more popular thing. For a while I have thought VR might be the killer app that makes it a reality.

For those interested, it was mostly just bodyweight exercises, eg between counter-strike rounds do crunches at desk, pushups, dips, etc. When I finally buy a house I have this idea that I want to design my computer desk to also be a workout desk... pullup bar and everything.
