GRINDERS FITNESS
Don’t fear the grind, respect it. Don’t avoid the grind, embrace it.
WHO WE ARE
Grinders Fitness is a boxing, kickboxing, and MMA gym located in Northglenn, CO. We opened our doors on September 12, 2016. Having been part of Title Boxing Thornton when it closed, we jumped at the chance to purchase all the equipment, partner with Albert Rosales and Shannon Sinn, hire all the trainers and open our own gym. We knew our gym would have cardio boxing and kickboxing as Title had, but we would be adding Brazilian Jiu Jitsu and MMA training. Taking inspiration from Albert and Shannon’s existing fight team, Grinders Submission Fighting, our new gym would be called Grinders Fitness. Our gym is a place for all fitness levels, with a tight knit and supportive gym family. Come see us!

MEET OUR COACHES
Shannon is motivated both by the fear of regret and never being satisfied with her performance. She is always seeking new ways to push herself and her conditioning! She brings the same drive and intensity to her classes and personal training sessions. Shannon is the perfect example of a GRINDER with a NO QUIT mentality.
She loves pushing her body beyond what she thought it was capable of and she also enjoys being a part of people reaching their fitness goals. “Being a part of Grinders is the best thing that ever happened to me. It has made me who I am today and it has made me a better person.”
What makes the Grinders gym special and unique to Kurtis is creating relationships and watching each other come together, pushing to make one another better, and the common bond of loving what we do.
