While each workout is different, there is a general format that all CrossFit classes follow, Ages says. "There's a dynamic warm-up, mobility work, strength and skill work, the WOD, and finally, a cool-down."
CrossFit isn't (always) a cult of Paleo adherents
While many CrossFitters probably do live by the Paleo lifestyle -- er, follow a diet that limits individuals to foods available during the hunter-gatherer era a la the caveman (think meats, fish, nuts, leafy greens, regional veggies, and seeds; and omits anything that comes in a box), it's a rarity in Mandelbaum's box.
"I don't recommend [following a Paleo diet] if you want to perform at a peak level," Mandelbaum says. "The body needs carbs beyond a random sweet potato!"
