Chantay comes from a background in health and fitness that spans more than 20 years. Beginning in the 1980's, her experience spans the entire breadth of the fitness industry, extending from hard-core bodybuilding to large scale fitness facilities to "South Florida Style" personal training studios to hospital rehabilitation and wellness programs. While her formal education at the Fitness Institute at Florida Atlantic University provides the basis for safe and effective training, it is her wide experience that allows her to successfully develop classes and individual programs that fulfill our members needs. 


With regards to her personal approach to fitness, Chantay has stated:


"I believe my best qualifications are my experience and my empathy. As a middle aged mother of 3, I have been in shape and out of shape at various times in my life. Also, I have had sport injuries from which I had to recover. The key to a successful fitness program is to keep your training interesting and realistic so it will produce satisfying results physically, mentally and emotionally. If your program does not do this, it's unlikely you will follow it for long. That is why I offer a wide variety of specialized classes. Together we can create a program that's tailored for your needs and desires that will change and evolve as you succeed."
