Follow the movement.
CrossFit is a strength and conditioning program designed to help people gain a broad and general fitness. CrossFit programming concentrates on constantly varied functional movements performed at high intensity to achieve overall physical fitness, so people are prepared for any physical challenge.
Greg Glassman, founder of CrossFit, says:
"Eat meat and vegetables, nuts and seeds, some fruit, little starch and no sugar. Keep intake to levels that will support exercise but not body fat. Practice and train major lifts: Deadlift, clean, squat, presses, C&J and snatch. Similarly, master the basics of gymnastics: pull-ups, dips, rope climb, push-ups, sit-ups, presses to handstand. pirouettes, flips, splits and holds. Bike, run, swim, row, etc., hard and fast. Five or six days a week mix these elements in as many combinations and patterns as creativity will allow. Routine is the enemy. Keep workouts short and intense. Regularly learn and play new sports."
