The authors of a bestseller suggest willpower is a finite but renewable resource.

So let’s say you’ve decided to give up sugar. On the first day, you skip your regular morning latte, evade the siren song of the doughnuts in your morning meeting, dodge the cookies in the lunchroom and turn down the candy at the checkout aisle of the grocery store.

Top scientists bust hydration myths at the 2015 CrossFit Conference on Exercise-Associated Hyponatremia.

In 1998, Dr. Dale Benjamin Speedy stood in front of Ironman competitors in Auckland, New Zealand, and prepared to make an announcement he knew was going to be unpopular: He told the athletes he was reducing the number of hydration stations throughout the race, which was made up of a 2.4-mile swim, 112-mile bicycle ride and 26.2-mile run.

Artist Karl Porter talks about how graffiti and CrossFit are healing wounds in the flashpoint city of Derry in Northern Ireland.

It was well past 1 a.m., and darkness blanketed the city of Derry, Northern Ireland. The streets were barren save for two teenage boys and their paint. Neither boy noticed the car’s approach until four masked men erupted from within. The vehicle was unmarked.

“Consume the maximal amount that can be tolerated.”

The line seems innocuous at first, just a recommendation in a 1996 position stand on hydration published by the American College of Sports Medicine (ACSM). But if you read it a few times, the words don’t sit well. Their imprecision alone seems enough to disqualify them from a publication titled Medicine & Science in Sports… Continue Reading

Peer review is held up as the gold standard of legitimacy in academic publishing, but Lon Kilgore says the system has inherent flaws and isn’t as foolproof as journals would have you believe.

As any reader of CrossFit.com and The Russells blog can attest, exercise-science journals seem to be suffering from compromised systems of publication and ethics.
