Nathan Koher
I'm a certified personal trainer with over 10 years of experience helping people become stronger, healthier, and more confident through fitness. Throughout my career, I’ve had the opportunity to coach clients one-on-one as well as lead small and large group training sessions.
I specialize in strength training and conditioning, Olympic weightlifting, weight loss, and senior fitness. My approach to training is built around the belief that nutrition and consistency are two of the most important factors in achieving lasting results. Exercise isn’t just about looking better—it’s about building a stronger, healthier body that can help you stay active, independent, and out of the hospital.
Most importantly, I want people to enjoy the process. Training should challenge you, but it should also be fun, comfortable, and something you look forward to. I strive to create an environment where everyone—regardless of age or fitness level—feels supported, motivated, and confident.
Whether your goal is to lose weight, build strength, improve your conditioning, learn Olympic lifts, or simply move and feel better, I’m here to help you stay consistent, enjoy the journey, and get the results you’re working for.
