The Reebok CrossFit Final Games 2011 is taking place in Southern California this weekend. Made for the true endurance athlete, the CrossFit games put competitors through a rigorous series of workouts to determine who is the fittest of them all. If you're unfamiliar with CrossFit, think of it like a boot camp on steroids; a CrossFit program involves exercises that build strength while also increasing endurance — sprints, weightlifting, plyometrics, and more. I once watched a CrossFit training session where I saw athletes go through an obstacle course that involved climbing over walls, hurling sandbags, lifting barbells, and tossing tires. The three-day competition is not for the faint of heart, but the payoff is huge — $250K to the first-place male and female winners.
