CrossFit programming is decentralized, but its general methodology is used by thousands of private affiliated gyms, fire departments, law-enforcement agencies, and military organizations, including the Royal Danish Life Guards, as well as by some U.S. and Canadian high-school physical-education teachers, high-school and college sports teams, and the Miami Marlins.
The Paleo diet, also referred to as the caveman or Stone-Age diet, includes lean meats, fish, fruits, vegetables, nuts, and seeds. Proponents of the diet emphasize choosing low-glycemic fruits and vegetables. There is debate about several aspects of the Paleo diet: what foods actually existed at the time, the variation in diets depending on region (e.g., tropical vs. Arctic), how modern-day fruits and vegetables bear little resemblance to prehistoric wild versions, and disagreement among Paleo diet enthusiasts on what is included/excluded from the diet. Because of these differences, there is not one “true” Paleo diet.
Sport-specific athletes – Like the specialists, if you are an athlete training for a sport, you’d be better off finding a coach that is trained in getting great performances out of athletes in your specific sport. Every sport has special movements that require certain types of power in specific muscles. CrossFit prepares you for everything, but won’t improve your specific sport skills unless you are training for those specific sport skills! Many athletes choose to combine CrossFit with sport-specific workouts (see things like CrossFit Football) in their off-season for conditioning, but that’s up to each sport’s coach.
But the truth is--and this is apparent to anyone watching Glassman wile away an afternoon at El Borracho--that CrossFit's success doesn't derive from any conventional business strategy. Glassman doesn't behave the way he's supposed to. Sometimes he rebels out of cunning, other times for the sheer petulant fun of it. Often, it's hard to tell which. As a result, CrossFit is a workout and a company no conventional trainer or M.B.A. would ever have built. Glassman is sitting atop a firecracker of a company. And the relevant question is, as always, What's he going to do now?
You're not tracking calories. You won't feel hungry. You won't be eating based on a points system. You're going to miss your morning doughnuts, but this isn't like any diet you might be used to. Whole30 co-founder Melissa Hartwig actually doesn't like calling the Whole30 a "diet" at all. “Most diets are spent white-knuckling your way through deprivation, restriction, hunger, tuning out your body’s signals, and obsessing over tracking and weighing your food,” Hartwig says. She doesn't think that type of behavior is sustainable, and if you've ever tried dieting, you probably agree.
