The title of the post is "Virtual Reality: My Digital Dojo for Mental & Physical Fitness". The post is about physical fitness and I think the author is conflating physical fitness with cardiovascular fitness.

And I argued for both and that strength training also results in cardiovascular adaptations.
How would the term physical fitness, used as the complement of mental fitness, not include the cardiovascular? The blog never claimed anything about bulking up or maximising strength!
What you said boils down to "but that's just cardiovascular, not proper physical fitness." By that measure, Lance Armstrong on the height of epo abuse wasn't fit.
