The novelty of VR aerobics will have the shelf life of Tae Bo, Jazzercise, on and on. I have seen more variations on this theme than the Fast & Furious franchise.
At least when you get sick of the workouts you still have the VR headset that can do other things instead of a rowing machine or treadmill that collects dust.
I even have a decent home gym but go to the commercial gym 90% of the time because working out at home is boring and demotivating. You can't replicate the stimulation of the gym at home. The ritual of going, the other people, not to mention the variety of physical stimulus.
