Personal Training

  For many years, Brent Brinkmeier, founder of On The Brink Fitness and Certified Master Personal Trainer, worked in just about every facet of the fitness industry, including big box gyms, in-home personal training as well as online training sessions. He came to discover his passion was strictly for one-on-one training in a private studio setting leading him to open On The Brink Fitness in 2015.  Brent started his fitness journey while attending Belmont University in Nashville TN. where he minored in sports medicine but soon realized that he didn't enjoy the injury treatment side of sports medicine very much. Shortly after graduating from Belmont University Brent got his first personal training certification in 2002.
