Sixty-seven minutes with two lightsabers and a heart rate that never dipped below “actually working.”

Beat Saber doesn’t look like exercise from the outside. From the outside it looks like someone flailing in a headset while neon blocks fly at their face. From the inside it’s a full-body rhythm game that doesn’t care what you weigh, doesn’t care about your pace per mile, and absolutely will not let you stand still. You move or you miss. That’s it. That’s the whole contract.

RAI streamed the whole thing on Twitch. Sixty-seven minutes live, in front of whoever showed up, slashing through songs with an average heart rate of 134 and a max of 157. That’s zone 3 cardio sustained for over an hour. That’s not gaming. That’s a workout that tricked the body into forgetting it was working out — which is the entire point.

838 calories. No treadmill. No pavement. Just a dark room, a headset, and the understanding that sometimes the thing that gets you moving isn’t discipline. It’s a high score.
