Hello, I'm Mandy Harbin. I am from Georgia but moved to Alabama in 2017 with my now husband, Stephen and wonderful children. I am a Product Owner for a medical software company, I work from home 40 hours a week and I'm also an online coach.

I started training in April 2018 for my first bodybuilding competitions. I fell in love with the sport and haven't stopped since. I was a competitive cheerleader growing up.In 2020 I earned by IFBB (International Federation of Bodybuilders) professional status as a figure competitor as well as a physique competitor.  

I am available to assist Gym Rat Performance Training athletes with meal plans and nutrition advice.
