Since starting personal training in 2014 I’ve had the pleasure to work with a wide array of clients, varying in age from teens all the way to people in their 70s and with goals ranging from competitive sports performance to those who simply want to reclaim their health and the ability to age well. My own fitness journey began in 2011 with the University of Iowa Powerlifting Club where I had the opportunity to meet, train with, compete against, and most importantly learn from some amazing lifters. Even if you don’t have aspirations of becoming a powerlifter there are still too many numerous benefits to resistance training to pass up on it entirely. Eventually I hope you come to enjoy training as much as I do and I can’t wait to help guide you along the way in your process towards better health and performance.

Personally, I believe the best qualifications for a trainer to be one's body of work in the field, but to that extent, a trainer should always be learning how to be better at his craft. In that pursuit, I have attained a B.S in Human Physiology from the University of Iowa and a M.S Ed, in Physical Education & Exercise Science from Northern Illinois University as well as USA Weightlifting Level 1 Sports Performance Coach and ACE Health Coach Certifications. With the right application of both experience and education I'm confident we can successfully work together to achieve your goals!
Jacob Stratton
Personal Trainer/General Manager

For approximately 11 years I have been training and competing in the strength sport of powerlifting all over the nation. My passion for lifting and training all started back in 2005 when I enlisted in the Marine Corps. Over the years I have had the privilege to train and compete with some of the strongest individuals in the world spanning from the Arnold Classic to the Olympia. I have experience competing raw, single-ply, and multi-ply. 
I have reached a point in my life where I want to educate and guide those who are willing to dedicate the time and effort into becoming a stronger healthier version of themselves. Having experience coupled with two National Academy of Sports Medicine certifications in Personal Training and Nutrition, I believe we can work together in accomplishing your objective(s).
