Brandon Fowler

Personal Trainer, Group Fitness Instructor

Brandon's Bio

Brandon was born and raised in the small town of Liberty, South Carolina. Brandon’s love for fitness and nutrition began when he read Bruce Lee’s ‘The art of expressing the human body’ at the age of 14. A multi-sport athlete at a young age, Brandon decided to focus on wrestling in high school. Trying to gain weight in the off-season and cut body fat during the season, he developed some unhealthy eating habits along the way. Reading and implementing every piece of information he could get his hands on, he did many of the wrong things before he found what was effective. In 2012, he received his Bachelor’s degree in Exercise Science from the College of Charleston. In college, Brandon spent three years working as part of the Sport’s Performance/Strength department with swimming, baseball, dance, and volleyball. He is a certified Strength and Conditioning Specialist, Certified Personal Trainer through the NSCA (National Strength and Conditioning Association) and is currently pursuing a degree in Dietetics from the University of Northern Colorado. Brandon believes in a no non-sense, balanced approach to nutrition, using the formation of habits to produce long-lasting results. He applies these principles of nutrition and fitness with clients to achieve optimal results. In his spare time, Brandon enjoys spending time with his wife, Ally, strength training, cycling, Clemson football and playing FIFA.
