Ice, Ice, Crazy: The pseudoscience of cryotherapy.

It’s happening again, we see it all the time, particularly in our sport. Guys filling up giant trashcans and filling them with bags of ice. They swear by it. And who can blame them? Every guest on Joe Rogan’s podcast does too. You can’t blame them either. At the elite level of any sport everyone is doing everything they can do maximize their recovery.

A brief and ridiculously biased review of Metamoris 4.

Metamoris: Ralek gracie claims the name came from a native American story that unites tribes of different backgrounds. Using Latin one could infer that “latin/ancient greek for “beyond ethos”.
“meta” means “beyond” (metaphysics, metareferential and so on), “moris” could be “customs”, “habits”, in that sense.”(Bubblun from Sherdog) Thus, the competition Metamoris seeks to show the effectiveness of a number of different grappling styles from around the world. It addresses the oldest question in grappling: Which one is the best? Folk style wrestling? Catch-as-catch-can? Brazilian Jiu Jitsu? Sambo?
