CrossFit is known as the go-to workout for many police academies, military special operations units, and professional sports teams. But it's also a workout that whips everyday folks into shape, from the young to the old, using the same exercises as the elite athletes. The only difference is that the exercises are adjusted to the individual's fitness level.

At GridIron CrossFit, coaches help CrossFitters discover how many reps are appropriate for them, and then monitor them in group classes. These classes rely on functional-fitness movements, training bodies to excel in real-life situations, whether that means lifting heavy bags of groceries or lifting a car off a penny in the grocery-store parking lot. The coaches also offer a CrossFit Lite boot-camp-style class for individuals who want to forgo heavy weightlifting, as well as a special class that readies football players for the field.
