Meanwhile there are martial arts and other physical disciplines where you go slowly to make sure you train the muscles along the entire movement instead of going in jerks and starts (which is how you damage yourself).

Fast iteration isn't about doing things faster. It's about requesting feedback more frequently. Which often means doing less, not more, and then evaluating the effectiveness of that small amount of work. Then adjusting your plans.

In writing, doing an entire book before your editor can tell you you're accidentally stealing a storyline from another author is bad. His analogies seem to be equating to this sort of behavior but missing the cause.
