Hello! My name is Bret Kliethermes and I have been working in the St. Louis area as a Strength & Conditioning Specialist since 2005. I have helped dozens of clients reach their Training Goals ranging from the Division 1 Athlete looking to improve his performance on the baseball field, to the local Accountant wanting to improve his performance in the world of business.
In the past five years I have worked and studied with some of the best minds in the Performance and Fitness Industry learning the best Protocols & Training Systems to improve Health, Performance and Body Composition. I look forward to sharing my knowledge to help you ACHIEVE your Goals!
When I’m not working with my clients I enjoy “Practicing what I Preach” and trying different types of exercise. For example, I am now doing Pre-Natal yoga with my wife Becky who is approaching her second trimester, Namaste! I also enjoy boxing, different types of grappling and various outdoor activities like hiking, camping, fishing and floating.
