Hi, I'm Cole.
I'm a Boxing & Athletic Strength coach in Colorado.
Cole
Rupenski
I've been training and practicing the art of boxing since I was 12 years old in three different gyms. The first gym I ever went to and trained out of was 4th Street Boxing Gym, led by Jim McGloughlin who is a Florida Hall of Fame boxing coach for professional boxers.
In college, I learned under Lee Gladden, "Coach Milk." for a few years. This coach pushed me to my fullest potential in the art of boxing and taught me how to break down the components of boxing itself. Lee Gladden was an Olympic boxer while serving in the Marines.
I currently train in Front Range Boxing Academy where Dave Gaudet has maintained the space to practice, learn, and perform the art of boxing for over 30 years. I have been boxing for more than half my life under the guidance of some of the best in the country and am confident I can help you refine your skills and share techniques that will allow you to level up.

I offer beginner, amateur, and pro-level mitt training work.
This part of my services combines curriculum from my weekly classes with the personalization of athletic and strength training.
Whether you are looking for some extra hands to help with mitts, or you need a coach to put a regiment together, I would be honored to be brought on board and share my expertise where it is most effective.
This service is primarily for folks looking for some form of personal training outside of boxing-specific training.
Here we can work on your specific goals whether it be weight loss, muscle group development, endurance training, or athletic performance - whatever is right for you even if it doesn’t neatly fit into one of those categories.
This is one-on-one training and truly geared towards your level of commitment to yourself so what you put in will be what you get out.

When I first stepped into Coach Cole's class, I was just solely seeking a workout—what I found was transformation. His demanding sessions pushed me beyond what I thought possible, building genuine strength—both physical and mental.
What makes him exceptional isn't just technical expertise, but his ability to understand exactly what each fighter needs. The confidence I've gained in his gym has changed how I handle every challenge in my life, and has made a difference that I can confidently say that I will be eternally grateful for.
