I did about 45 minutes on my Oculus VR. I did the supernatural app. I did a 30 minute workout to get the hang of it. Then about half an hour later I tried an actual workout. You have to knockout these block things with the controllers that are flying at you. Some of them you have to knock out a certain way. Then they have these things coming at you that you have to either dodge to the left, right, or duck. You do it to music too. I was working out to an Imagine Dragon song. And they have virtual coaches who tell you what to fix and to encourage you.
I was out of breath after 15 minutes.
They don't make these model VRs anymore and the new ones are about $500. So I'm glad I got mine because this seems like it will be a good thing. I'm not a gym guy.
