Eclectic native Katrina Shaw started a fitness craze when she cranked up her usual fitness routine with martial arts moves and punch and kick combinations. With a background in martial arts and more than 25 years of personal training experience, Shaw created Box Mania with fitness goals in mind – and she got national results.

Box Mania is a partner-based workout in which one person holds a target while the other strikes it with punch and kick combo intervals, pushing through the reps and then trading places to hold the target for the partner. The routine incorporates techniques from Taekwondo, as Shaw is a second-degree black belt instructor.
