DANIEL DUANE: Everything You Know About Fitness Is A Lie. I think he’s way too hard on alternate workouts — I haven’t done CrossFit, but I know people who have benefited a lot. And the stability-ball stuff has done wonders for my computer-related maladies. But there’s also something to be said for the back-to-basics routine he champions, and I’m a big fan of the Rippetoe books, which I’ve mentioned here before. But I think CrossFit is even based on those. So Duane’s overselling his thesis a bit.

Check out this book from Rippetoe, too.

UPDATE: An email from Brian Mulvaney at Crossfit:

Wanted to pass along regards from Greg Glasman the founder and CEO of CrossFit, Inc. We are very big Instapundit fans here.

Greg would like to relay that CrossFit is in no way preceded by any of Rippetoe’s work. Further, “We are fundamentally at odds with Rippetoe on critical points of method and charter. We replaced him with Louie Simmons, the dominant authority of his field.”

I stand corrected.

ANOTHER UPDATE: And an email from Rippetoe himself:

Big fan here as well. It is absolutely true that CrossFit preceded my work, and that I was not aware of CrossFit until after my book had been published. It is also true that I am fundamentally at odds with CrossFit on critical points of method and charter (whatever “charter” is), and that was one of the reasons I discontinued my association with them. But they replaced me with Louie Simmons, whom I greatly respect, AFTER my decision to leave. I feel it is important to note the correct timeline here, since the implication that they terminated me is false.

Who knew that all these people read InstaPundit?
