The trainers at Odyssey Athletic Center know that a single approach to physical fitness is as boring as it is limiting. They bear certifications and degrees from a variety of disciplines, earning the recognition of workout guilds ranging from the Aerobic & Fitness Association of America and the World Instructor Training School to the American Council of Exercise. This knowledge of different exercise systems enables them to host 60 classes per week inside their 27,000-square-foot facility. Their scheduled Pilates sessions help students nurture lean muscle without bulk, and Zumba meetings melt away calories with fun dance steps set to a Latin beat. To ensure they stay informed on emerging fitness techniques, staff members attend continuing-education classes and hold weekly question-and-answer sessions with their dumbbells.
