Who We Are

I am South St. Louis, born and raised. I love this city. I graduated from SLU and WASH U ROTC, against a lot of odds, and have been in the Missouri National Guard almost 20 years. I started BioFit to elevate my home to a level we haven’t experienced in many years. I intend to use the latest fitness technologies and my passion for training and coaching to uplift as many humans as I can to make this city reach its full potential. I am a self-proclaimed biohacker and futurist and I have dedicated my life to the elevation of not only our city but the people in it.

I grew up in South City St. Louis, graduated from St. Louis University High School with First Honors in 2004, and then obtained my Bachelor’s in Business Administration from Loyola University Chicago in 2008. For the first time in my career, I am genuinely passionate about what I do for a living! Joining BioFit showed me that a career doesn’t have to feel like a job. It brings me great joy to educate our clientele and watch them grow into better and stronger individuals.

Morgan Mars BioFit StL Facilitation Specialists

Growing up in St. Louis and moving around the area my entire life, I quickly became fascinated with the intricacies of the human body and how to optimize its functionality. After graduating from Marquette High school a semester early, I pursued my passion for physical and emotional wellness by becoming a personal trainer in 2017. Since then, I have made it my mission to continue educating myself to provide my clients with the best possible results. With BioFit, I have found the perfect platform to help individuals become their best selves.

I've been coming here since January 2020 and I love it. I've lost 35 lbs and reshaped my body thanks to the help of John and Andrew. While they wouldn't take credit for the diet side of the ledger, they do get credit for the physical reshaping and the atmosphere and community that's been established. So, if you like science, data, biohacking, have a bit of entrepreneurial bent, and value your health and vitality as much as you value your time... this is the place for you.

It was a game changer!

A friend of mine introduced me to Biofit in December. It was a game changer! I have been working out consistently for 28 years; running, lifting weights, spinning, yoga, pilates, barre, etc. I have tried every workout there is; some have stuck with me, some have not. Even though I have lifted weights for 28 years, there was not anyway to push myself beyond what I was doing…. until Biofit. In these past few months I have become stronger and I have felt muscles I had never been able to work before. John and Andrew are amazing; they are passionate about helping people reach their fitness goals and always fun to train with. The combination of the ARX equipment and the motivation from John and Andrew makes these workouts hard to beat!
