Why Blue Collar Fitness

We started Blue Collar Fighter in 2006 because the West Valley needed a quality strength athletics club. Having trained at all of the major clubs in town before then, we were continually disappointed with the lack of personal instruction, high rates, contracts and lack of dedication from the students and instructors. Our goal is to make you a member of our family, increase your quality of life and help you learn that there is no substitute for strength; body, mind and will.

Our instructors are seasoned, knowledgeable and experienced athletes dedicated to training and the future of strength athletics. We’re not a huge, sponsored club with thousands of students, and you’ll see why it makes a difference!
