I'm interested here, could you elaborate? What are you doing to replace the gym? Workouts led by a virtual instructor? Presumably cardio? Super interesting and I'd love to hear more!
Mostly FitXR, which VR shadow boxing set to music (with squats mixed in), but I also play some beatsaber to warmup and cool down. The former is designed for fitness, the latter is more of a game like DDR that can get sweaty. There is supernatural and a couple of others, but I mostly stick with FitXR because I’ve found some music and sets to like over the years.
