OG Fitness Has Helped People Get Life Changing Results

In 2014 our owner, Keilah Rios, became a certified personal trainer and over the following 6 years she assisted in management and operations of 2 boutique training studios in St. Cloud Fl, one of which she helped to open in 2016 with another trainer.  During that time she was able to build her client list and professional reputation as a personal trainer in St. Cloud that specialized in corrective exercise, weight loss, muscle gain and mentoring of newly certified trainers.

In 2020, at the beginning of the coronavirus pandemic, when gyms were forced to close, she had the opportunity to purchase fit l1fe.  Soon after, we rebranded and started looking for a new location.  Our location at the time was only 970 sqft which was not going to work in a post-corona world.  We finally came across a 4600 sqft air conditioned warehouse space.  Keilah was able to secure this location and set to find like-minded trainers who wanted to help build a comprehensive training space focused on health and fitness education for trainers and clients alike.

OG Fitness is now a team of Certified professionals with specialties in Strength and Conditioning, Athletic performance enhancement, Senior Fitness and wellness, Corrective exercise for post injury recovery, Weight loss, Hypertrophy, Core strengthening, Balance training, Flexibility training, Sports Nutrition, Health and Wellness Coaching, Mobility and so much more.  Our goal is to house the services that most serve the public in leading happier and healthier lives and to mentor the future of personal training so that they understand the importance of prioritizing education and client care.

All OG Fitness Services Are No Contract, They Are Pay-As-You-Go!
