I'm skeptical about working out with a headset, at all. There are probably some good use cases, but I'm just mentally going through the stuff I'm doing at a gym, and I think that typically a headset would be either a hazard or a gimmick of questionable usefulness.
Try Supernatural. It’s like a dance, boxing, or martial arts workout. My VR lab is a little small and has slanted ceilings so I have to be careful not to hit the tips of my fingertips but it is a real workout that is reasonably safe.
