I know. I was just pointing out one of the many limitations there are to using high school physics to define fitness. There are probably many more limitations but why go into them? It's like proving why is x is not true using two different proofs. What's the point?

Just so there's no confusion the majority of those ridiculous kips were in fact not "muscle ups" but either "Kips to support" or "Uprises" two completely different movements to muscle ups but not ridiculous by any means...just mis-named on mainsite...although I think the latest video they correctly labeled as 30 Back Uprises for time.

The lack of physics understanding can be negated by having rudimentary forumulas tattooed on one's body.

Shane,

We are in agreement, I was just pointing out that "work" has other meanings beyond mechanical and that the body is much more complex than people here try to make it out to be.

I have never met a physicist with a formula tattoo.
