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!
