Javier Lozano Jr.'s passion for physical fitness began during his martial-arts training. Since then, he's become a personal trainer certified by the Aerobics and Fitness Association of America and the International Sports Science Association. He's also a black belt in Wado Kai, and a Colorado-state karate champion. Along with his wife Susan, who is a certified boot-camp coach, he shares this passion for fitness with others during intensive indoor and outdoor boot-camp classes. During the always-changing sessions, the Lozanos help clients of all fitness levels sculpt fitter frames using functional movements augmented by kettlebells, resistance bands, and plump sandbags. They aim to further the effects of these workouts with their complimentary nutrition program, which overhauls unhealthy lifestyle choices with practical plans for swapping out bad diets with proteins, whole grains, and nonwax fruits.
