The thing that I love about CrossFit is how effective it is. A well done class program, with maybe a competitor extra, seems to give you about 75% world class fitness in about an hour to 90 minutes. The kinda funny thing is that as soon as you wanna push to the higher end of the sport, you almost completely go away from something that looks like that session. To be in the top .0001% you may not even do a “CrossFit” workout every day, or week. The boring answer for “do we have best practices” is probably no, but we can imagine that they will be athlete centered, individualized, and data based, utilizing a team of people to help that athlete succeed. It won’t be any one thing, or philosophy, or sauna session etc. It will be finding people who are genetically gifted and motivated, then working with them to develop against the field for years and years, adjust things up and down, and hope they get lucky. We have some historical data that tells us we need to be a certain speed and strength and skill level, but because the sport is not fixed we have the joy of doing our best to read tea leaves and star charts as to how the fittest on earth will be tested at a given event. That is not a very marketable answer though. It is like the classic coach answer of “it depends”.
