Meet The Trainers

William McCray - Owner

Certified Personal Trainer and Fitness Nutrition Specialist


B.S. in Kinesiology, Michigan State University


Muscle Development, Weight Loss, Core Sculpting

I train on the principle of muscle confusion, meaning I never allow your body to get acclimated to a particular routine, therefore always keeping your muscle fibers engaged. I fell in love with fitness at the age of 12, when I got a weight set for Christmas. My passion comes from witnessing numerous close family members pass away from health related issues. Not wanting to meet that same fate, fitness has become a lifestyle for me. My goal is to help transform as many bodies as I possibly can. Do you have the WILL to win?
