A Note from the Founders

One Nation Fitness Co-Founders
Hey there – thanks for stopping by!
We are Daniel and Kate Grochowski, longtime fitness advocates and proud Americans. We started One Nation Fitness in response to the broken state of our nation. Our goal is to ignite change by building a community based on a passion for fitness and a desire to reunite our once United States. 
You can get a better sense of the One Nation Fitness community by taking a look around. What we write and what we design is inspired by personal encounters in the gym and in daily life. We encourage you to check out our words of wisdom and our gear in the hope that you are challenged to better yourself, our fitness community, and our great nation. 
Finally, we would really love to keep in touch, whether that’s saying hey, following our journey, diving deeper into our vision, or requesting a new tee design – just drop us a lineWelcome to something greater than yourself. Welcome to One Nation Fitness.
In God We Trust,
One Nation Fitness Co-Founder Signature
