Momentum Taekwondo Academy, Scottsdale

Taekwondo master Diane Muniz doesn't just equip her students and set them loose—she trains right alongside them. That's because her main goal at Momentum Taekwondo Academy is to keep everyone moving and growing both physically and mentally in the art of tae kwon do, herself included. Armed with a fourth-degree black belt, she and her students work on the footwork and dynamic movements distinct to the Korean martial art at tae kwon do classes. Or students can opt for kickboxing to add some extra calorie-burning to their martial-arts regimes.
