Inside CrossFit North Little Rock's utilitarian gym, people are flipping tractor tires, jumping onto boxes, and slithering up ropes. To the uninitiated, it may look like chaos, but CrossFit's system has a method to its madness. That method is based on constantly varied functional movements performed at a high intensity.

Perfecting and strengthening movements such as jumping, squatting, bending, and lifting translates to everyday activities as well as all sports and work activities. That's a big reason the gym's trained instructors choose it as their primary fitness system, and the fact that it's scalable to all fitness levels and ages is another. They're also able to change the workouts each day, which keeps the boredom of repetition away. Finally, their group sessions foster team spirit, which keeps inspiration high and motivation at the ready.
