Aye. There are SO many confident coaches, practitioners, athletes, nerds; but they'll just as confidently tell you to never skip breakfast to kick-start your metabolism, use cup-suction to massage your muscles, and all sorta of firm advice on exercises grouping intervals posture etc; and yet, it all just seems to trickle down to "common wisdom" and "accepted truths", or most of all "This is what I've personally observed works" for some given value of "observed" and "works". I think it's an area that IS hard to scientifically study - the bodies, goals, and progress are all so frequently and radically different, and confounding variables are everywhere - but for a lot of coaches it's not even a goal; there's a complete lack of humility in any coach, fitness trainer, or even phys ed teacher I've ever seen. There's a LOT of anecdotal certainty ("I've seen this work well"), and little solid demonstrable repeatable evidence.
