I had the pleasure of training at CrossFit 646 for about six months while my wife and I were in Tucson for her travel nurse contracts. Matt and Mel run an excellent gym with very knowledgeable coaches who take the time to help everyone improve.The community is incredibly welcoming, it quickly became the place I looked forward to showing up to. If you're in Tucson and looking for a great CrossFit gym, I highly recommend dropping in and signing up.Thanks again for welcoming me in, hope to make it back someday to the sunny south!Cheers from Canada - Ben

CrossFit has greatly improved my health and overall well-being. It has helped me build and maintain muscle, increase strength and endurance, and keep my weight at a comfortable, sustainable level. I feel stronger, healthier, and more confident both physically and mentally.The instructors are extremely knowledgeable and always accommodating, making sure workouts are safe and tailored to individual needs. The gym is more than just a place to work out, it’s a true community that is supportive, motivating, and welcoming. This combination of expert coaching and a positive environment has made CrossFit an enjoyable and lasting part of my lifestyle. Christian, Mel, Matt, Sam, Maia, and Anthony deserve a shoutout for their example, kindness, patience, knowledge, and dedication. They’re all awesome instructors!

A CrossFit gym with the greatest coaches and programming you could ask for. Of the many things I appreciated during my time at 646 are the long dynamic warm ups, the intentional progressive overloads, and the advanced instruction.
