I've been playing Beat Saber for a few months now on the regular as a means to exercise. But I'm starting to hit a plateau in how demanding it is. I kind of want to increase the difficulty to get a more strenuous workout. I'm sitting at Expert difficulty doing just fine but it takes like an hour+ of play to get really tired anymore. Expert+ is a level of difficulty jump that's ludicrously huge. 
It goes from being able to reactively playing songs to needing to rehearse them over and over to get right and it's just not fun or easy.

So I am looking for alternative game suggestions to get an exercise experience from that might be similar to Beat Saber in that it's fun, you listen to great music, and exercise.
