The most secretive body parts are muscles, which hide behind layers of skin and appear only occasionally to help lift cars off trapped kittens.

CrossFit's motivating, skilled instructors will push exercisers of every level to their full potential. Each day, they throw down a fresh guerilla-ambush worth of challenges for your muscles and your brain, fueling constant gains and keeping you engaged. Over the course of the one-hour session, you'll run, jump, lift weights, slam out push-ups and chin-ups, chase chickens, punch slabs of beef, and end with a live crocodile wrestle. In the heat of your workout, you'll sweat out weakness, fear, and monosodium glutamate, while beginning to gain the functional, unsurpassed strength of a body in fluid, powerful motion. Although there's an atmosphere of combat readiness, CrossFit instructors vary the weight loads and number of reps so that everyone—from students to firefighters to grandmothers—participates.
CrossFit makes it easy to find time to workout, with class sessions generally beginning at 5:30 a.m. and running until 6:30 p.m. throughout the week. Check the schedule for details, and call or e-mail ahead to schedule your classes.
