RSIN Fitness: Inspire. Teach. Motivate.

At RSin Fitness founded in 2020, we believe in the power of hard work, dedication, and the right guidance to unlock your full potential. Our journey began from a personal experience—being a high school athlete without a trainer to help push past my limits. Every achievement was built on relentless effort, dedication, & hard work. RSin Fitness was created—to fill the gap for the next generation of athletes and individuals striving for their best.

We provide in-person and online training for athletes of all ages and anyone ready to take control of their fitness journey. Whether you’re looking to improve performance, build strength, or adopt healthier habits, we’re here to guide you every step of the way.

Our Mission
We exist to inspire, teach , and motivate people to build lifelong strength and health through real, sustainable habits and consistent progress.

More than just training—we provide coaching, support, and the mindset shift needed for lasting success. Whether in the gym, online, or through our exclusive RSin Fitness merchandise, we empower you to push past limits and redefine what’s possible.
‍
RSin Fitness. Your Journey. Your Strength.

DON’T BE LAST!

Rudy was a great personal trainer for me. My son also attended an agility camp with him. In different settings, Rudy was able to inspire both of us to continue our fitness journey with more knowledge and a joyful approach. He pushed us to accomplish things we never would have done on our own. Along with a positive healthy lifestyle approach, we are both more confident and willing to try new things!

Rudy brings serious energy and intention to every session. He trains with purpose, never going through the motions, and his drive and discipline set the tone from the start.

My son, who plays Premier soccer, has been training with Rudy in his Sports Performance class at GreatLife, focusing on endurance and agility to elevate his game. Rudy’s passion for coaching truly stands out—he instills dedication, perseverance, and a strong work ethic in every student he works with.

I also had the pleasure of working with Rudy as my personal trainer for a year. During that time, he helped me tone up and build strength I never thought I had. He’s not only knowledgeable and skilled but also incredibly personable and motivating. I highly recommend Rudy to anyone looking to improve their fitness or take their athletic performance to the next level. He’s an incredible coach and an even better person to have on your journey to better health.

Monica D.

We have had an amazing experience with Rudy training our middle school daughter, Shikago. Rudy has great energy and relates really well to young athletes. He is always happy and smiling which motivates her to attend the early morning sessions. He genuinely cares about helping her grow as an athlete and as a person. He encourages her to work hard every day and give it all she has. Not only has she become stronger and faster she has also built confidence since working with Rudy.

Cayla R.

Rudy worked with my son last summer and he can’t wait to work with him again this summer. The training sessions that Rudy designed helped my son’s speed, acceleration, strength, and endurance. Rudy is also an extremely positive role model - pushing my son to do his best in athletics and in school, stressing the importance of good character, and overall boosting my son’s confidence. We are very fortunate to have found Rudy!

Kristin W.

Rudy worked with our son, Landon on speed and position-specific running back training. Rudy taught Landon the technical skills that could be applied in real-time, in-game situations, which improved his overall performance as a running back. Rudy is incredibly talented at connecting with his clients and pushing them to their full athletic potential. Landon looks up to Rudy as a role model and mentor and often seeks advice from him.

“Rudy truly changed my life.”
When I first met Rudy, I was underweight with little to no muscle definition and dealing with chronic back and neck pain. From day one, he took the time to really listen to my goals and concerns. He created a customized workout plan that not only built strength and muscle but also improved my daily function and overall quality of life. My goal wasn’t just aesthetics—it was to feel strong, healthy, and capable in a sustainable way. Rudy pushes me, believes in me, and has helped me unlock a level of strength and confidence I didn’t know I had. I’ve grown so much under his guidance, and the results speak for themselves—and continue to. I’m so grateful for his support and expertise.
