Gayle Smith has a lot of experience in the fitness industry: after all, she started when she was 13, which is when she started volunteering as a gymnastics coach for a non-profit community organization, Cambridge YMCA. Interested in the human body and its limits, Gayle pursued her passion and became a nurse and a fitness instructor. Her knowledge of health and wellness helped her create her own fitness center, G Force Fitness, where she offers personal training sessions as well as boot-camp classes.
