Husband-and-wife team Damon and Priscilla Stewart have turned their 11,000-square-foot gym into a veritable fitness factory. With the help of a smattering of barbells, Damon's nearly 5,000 hours teaching CrossFit, and constantly changing daily workouts, the duo churns out more chiseled bodies than the assembly lines that manufactured Michelangelo's sculptures. Along for the ride are coaches with résumés that cover everything from college sports, multiple marathons and triathlons, and careers in law enforcement.
