I personally started out with Supernatural, which is "Designed" for fitness and has classes with real instructors, but have since moved over to beat saber. They're similar, but whereas Supernatural still "feels" like a workout thanks to the coaches and stretching routines, beat saber just feels like a game but I still break a sweat.

I've played a lot Beat Saber, and ended up getting wrist weights. Very recently I've been spending time in Thrill of the Fight. I would never have expected myself to like it, but it's a fun workout.

Supernatural is my favorite and the one that I use most consistently.
