Kelly Beriau

Group and Personal Fitness Trainer

Kelly2After earning my B.S. in Health Education I pursued a career in the fitness industry. To embrace my passion for educating individuals and helping them achieve their goals I worked as as a group and individual fitness instructor at a former Boston studio.  I now use that experience and my years of competitive figure skating and cheerleading as inspiration to help others achieve their goals through behavior and lifestyle changes and improving one’s mind body connection. Since I am no longer a competitive athlete I realize I no longer need to train like one, this has lead me to ReDefine my physique, redesign my daily workout regimen, and reeducate myself on muscle movement. Over the years I have learned that every body is different and everyone has a different learning style. I am able to customize an individual’s plan based on their own needs, goals, body type and understanding of their muscles by enhancing their mind-body connection. My personalized, hands-on approach results in longevity, proper alignment, and beautiful long lean muscles, ReDefining the way we look at exercise.
