AVERAGE JOE’S WELCOME

That's why at Trivium Personal Fitness, we've designed our gym in Affton, MO to accommodate everyone from the Average Joe all the way up to the Olympic athlete. Our friendly and patient staff is here to answer your questions, assist your needs, and help you achieve a healthier, happier lifestyle.

We want to provide the most bang for your buck by offering access to the equipment, classes, and training you need to enjoy a healthier lifestyle. To better meet your fitness needs, we offer a variety of different fitness packages that you can check out on our Membership page.

I was pretty nervous about going to a Personal Trainer because this was my first time hiring a professional. From the moment I walked into Trivium Personal Fitness, I was welcomed with a non-judgemental and friendly attitude....

Working with Trivium helped me to achieve my goal of gaining weight the correct way. Ryan uses science and physiology in his approach rather than pushing fad exercises/diets and pushing supplements that don't work.

Christian Hatfield

I would highly recommend Trivium to anyone looking for a new gym or personal training. The gym has your standards (weights, racks, benches) but it also has open areas for functional training and classes with the equipment to match. The staff is knowledgeable, and I can attest that Ryan is continually searching out the latest research to incorporate into the gym's offerings. If you're looking to avoid the cookie-cutter gyms and step into an atmosphere dedicated to getting smart, safe results, give Trivium a shot.

Brianna O’Hara

Trivium is the place for me! They offer customizable workout plans based on my needs!

Sam Buckle

Trivium can really change your life as it has done to mine , the knowledge and skill base I’ve required from Ryan is unmatched from any other trainers I’ve worked with he will teach you the why, hows, when’s, and the what’s highly recommend!

Cari Stewart

I have been putting off exercising and weight loss for years, and was scared walking into a gym again. This was nothing like I expected! I've hard health scares recently, and this was a little intimidating at first, but Ryan really knows his stuff, from nutrition to how the body works, to what exercises are going to do the best for me. I am so happy to have overcome my "gym fear."
