Yeah. I think doing more of what you enjoy, and only just barely enough of what you find unpleasant or tedious, is the only sensible way to organize your workout. (With a possible exception for competitive athletes, who may have to do more than "just barely enough" if they want to stay competitive.)

It's the disdaining that seemed odd to me. Saying, "I don't like high-volume cardio, so I do just barely enough" makes perfect sense. Poking fun at the people doing high-volume cardio seems weird.

On the other hand, if mentally writing your blog post about how foolish those guys pounding out miles on the treadmill at the fitness center helps you get it together to do one more set, I suppose that's harmless.
