I tend to agree—if you're at a point where you can do it. But for a lot of people VR will end up being better for the simple fact that it'll actually happen for them.

Personally, I do go on extended walks regularly, e.g. do a couple miles to the grocery store—but, I was trying to get back into an actual strength training routine after years of no formal workouts, just walking, and gaining skill in Beat Saber was actually the first stepping stone that eventually got me back into it. Just needed some kinda tiny success first, just some experience using my body in a relatively athletic mode again.
