My passion is yoga, strength, and cardio training. My love of health, nutrition, and fitness has led me down many paths of fitness programs. However, four years ago I began doing power vinyasa yoga, which became the focal point of my fitness regimen. Yoga then became my passion and I decided to complete a 200 hour teacher training through Twin-Cities-Yoga which I completed in 2014. In addition to being a 200 hour registered yoga teacher, I am also certified as a PIYO instructor. PIYO is formatted on the principles of yoga and pilates, while bringing in the components of dance, calisthenics, cardio and strength training, PIYO was a program that brought my fitness passions together. I am excited to bring my energy and love of fitness to Core Fitness!
