I got Box VR a few minutes ago. It is a boxing trainer. I did three two minute sessions and one four-minute session. I am impressed.
The trainer shows me how to jab, uppercut cross, duck, and dodge. then it puts me in a left stance for two minutes followed by a right stance for two minutes. In each stance colored balls (blue for the left hand and red for the right hand) move from the far wall toward me in time to the music. It starts out easy enough and gradually picks up the pace. the balls indicate which technique to use with jabs predominating.
Between this software, gun club VR and another shooting game I have I manage an hour of entertainment with plenty of movement every day.
I look forward to the improvements I know will come as the graphics cards get better.
If you have not considered trying VR you ought to.
