VR exercise is a remarkably poor allocation of time (if your interest is physical fitness, efficiently). It also leaves out the most important adaptation of all: strength. Effective training (not exercising) requires a progression model. That is, on some time frame you must exceed your performance at the end of that time frame when compared to the beginning of the time frame. This must be done in some measurable way-…
This post is clearly about cardio while your whole comment dismisses it for not being strength training and talks of strength training. Just because you do strength training it doesn't mean cardio is useless and in fact many people do both. As for progression you do it the same way as running presumably - by putting more time and/or doing it faster.
> in fact many people do both.
And I argued for both and that strength training also results in cardiovascular adaptations.
