Ryan and Michelle Stemper

Founders

Whole Strength started in the garage of our South Nashville home in 2013. What began as a simple setup with a few barbells and a passion to help people has grown into a thriving fitness community that’s still rooted in the same mission we started with; to empower everyday people to win with their health and fitness.

We’re Ryan and Michelle Stemper, and we’ve been on this journey together from the very beginning. Back in those early days, we didn’t have much. Just a garage, a handful of friends who were willing to trust us, and a deep desire to help people get stronger, inside and out. Some of those first garage members are still with us today. They’ve seen firsthand how far we’ve come and how faithful God has been along the way...

Originally, Ryan thought his future would be personal training in a big commercial gym. But after discovering CrossFit and experiencing the power of a close-knit fitness community, everything changed. The vision became clear – to build something smaller, more intentional, and more relational. A space where people feel known, challenged, and supported. A place where transformation goes far beyond physical fitness. Our faith is the foundation of everything we do. We believe that health is a gift and stewardship is a calling. Whole Strength exists for the glory of God and the good of mankind. To serve people well, to restore health and hope, and to create a community that reflects His love through action.

As parents of three boys, we’re reminded daily that our health is not just about us. We want to set the example; to be strong, present, and ready for whatever life brings. That conviction drives us to help others do the same. Whether you’re just getting started or ready to push toward new goals, we’re here to walk alongside you. You don’t need to have it all figured out. You just need to take the first step. We’ll meet you there.

I came to CrossFit seeking a way to compete – something I missed out on as kid. What I found was a methodology that will provide me with means to move well for life. I hope to help people fall more in love with moving well, regardless of their experience, for the rest of their life.

My path to fitness began in 2012 after I accepted a challenge from a friend to do a CrossFit workout. The workout was humbling which led me to turn my life around. I became a coach, because I was blessed to experience the positive physical, mental, and emotional effect of what CrossFit can offer. As a coach, I have an opportunity to impact others to find their passion for health and wellness, while encouraging them to achieve their personal goals.

CrossFit Level 2 Coach, Level Method Certification, A.S. In Recording Arts, GIAC Cloud Security Architecture and Design Certification

I spent 15 years as a recording engineer in the music industry, living on long hours, unpredictable schedules, and quick meals. It was an incredible experience, but eventually, my priorities shifted, and I found myself in cybersecurity-a very desky desk job. My fitness journey was inconsistent at first, but everything changed after Whole Strength’s first nutrition challenge-I lost weight, gained energy, and felt better than ever. I walked in the doors of Whole Strength to make changes to myself, but stayed because of how fulfilling it is to share this very personal journey with others.

Jasmine Rogers coach at Whole Strength CrossFit & Nutrition

Dr. Jasmine Rogers

Nutrition Coach

Doctor of Chiropractic | B.S. in Nutrition | HSN Certification

As a chiropractor, I’ve always wanted to help people create lasting change to their health through better nutrition. What I’ve learned through years of experience is that chronic pain often stems not just from poor movement, but also from inflammation caused by unhealthy eating habits. Simple changes like drinking more water or eating more vegetables can significantly support recovery. That’s why I love the HSN approach at Whole Strength—it supports sustainable nutrition and lifestyle changes through a holistic, whole-life perspective.
