Yes, that website is all about training and correct swim technique and is certainly not a speedo fantasy board.
The shot* from CD on breastroke mistakes is very good and is in fact repeated in the other direction - but it is a very complicated site with lots of video shots under "lessons". The girls are in these as well however and there are bodysuits being worn on occasions so it needs a lot of sorting to find any guys in speedos, let alone a nice brief racer which were a delight to see in competitions in what seems now to be the very distant past.

*all the speedos seem to be anonymous but that guy alone seems to be wearing an intriguing club suit with symbol and letters.
