Actually Paulo, I am a swimming coach. I sure wish that caf0 got more than :08 per 100, but she got what she got, results vary. If she were to request a refund, I would give it. That said, :08 per 100 is not too shabby, although you may promise a greater payoff with your free advice, and you may have the ticket that makes her much quicker.
So, yes, as I said, I am a swimming coach. And what I do is not snake oil. I teach a very simple, basic set of abilities that are common to all elite swimmers: timing of the legs, arms, head and torso. You don't have to take my word for the existence of these timings in elite swimmers, read Maglischo, or even Doc Counsilman, who was the first to characterize the most common kick rhythms and their timings. Maglischo noted that the timings are so common among the elite that he worked with that it was "seldom a problem". Having done this for many years, developing swimmers from the ground up, I can say that in the non-elite, it is quite often a problem, so in this I suppose I disagree with Maglischo. I didn't invent this however, I was taught by a great mentor, a coach named Bob Mattson, former world record holder himself, and coach of many, many elite swimmers from his club in Wilmington DE. He too is one of the coaches that I rate as far better than myself, Rappstar, or Paulo (if it's he's not you).
And guess what? I AM doing it every day. Either reviewing athlete video, swimming myself, coaching workout, talking to my network of coaching friends, re-re-reading Maglischo while I bike on the trainer, or answering questions online. No, I am not a high-profile coach of world-class triathletes at this time, though I work with some pretty good ones.
