My experience over the past nearly-four years at Crossfit 646 has been nothing short of excellent. The atmosphere is positive, encouraging and motivating and this is a direct reflection of the owners' attitudes; coaches and members in turn benefit and project the same. I'm a bit outside the usual demographic for a Crossfit gym but have been trained hard and intelligently for my particular goals and circumstances (a 70+ y.o competitive weightlifter). If you want to improve and are willing to put in the work with a great attitude, I would highly recommend Crossfit 646 and owners Matthew and Melissa York!

My teenage girls go here as a part of SAVA, a volleyball club. They are gaining strength, endurance and confidence! Love crossfit!

I was in Tucson for work and dropped into CrossFit 646 twice during the week. The first time I dropped in Courtney was coaching the CrossFit class. She was really welcoming, made the class fun and explained all of the movements very thoroughly. The second time I dropped in it was open gym and the owner Melissa was very nice and showed me all the equipment I wanted to use for open gym. The gym was clean, the equipment was well kept and everyone was very nice. As someone who competes in Olympic weightlifting, I really appreciated the nice platforms they have and that all the weight is in kilos and not lbs.

This is my first time doing crossfit and the first gym I visited. I am beyond happy with my decision! The coaches are incredibly skilled in their ability to program workouts and translate the mechanics of various lifts. You can tell they are truly passionate about what they do. I've always read about how crossfit gyms have a community/family spirit and that is 100% accurate. I've met so many great people already and love that everyone there wants to support each other help others improve. I highly recommend coming to 646 and giving it a shot!

I loved my drop in workout here! The coaches responded to my email questions about a drop in within hours and Matt was a great coach. The box is a good size, everyone was nice and the workout was a killer. I'll come back here the next time I'm in Tucson for sure.

Drop in rate of $20 is pretty standard.

Great box. Friendly atmosphere. I loved learning new techniques from Melissa, the coach at the 6am class. Thanks for letting me drop-in!

I have hated working out my entire life. Cardio, weights, I dreaded it all. The trainers at this gym have inspired in me a passion for working out. I look forward to the workouts each week. There is truly a family at Crossfit 646 consisting of all ages and capabilities that all support each other in all our accomplishments. The trainers truly care about each of their members and go above and beyond to help us achieve our goals. Don't know what my life would be right now without this gym!

The trainers, Matt and Melisa are awesome, they take the time to train you right and to your abilities. It's more like a family of sweaty friends that all help you work out to maximize your workout.

I started working out here about 7 months ago and it's really amazing. I love having both the River Rd and Marana locations to choose from with all the same coaches I already know. I started with one-on-one personal training with Mel for about 2 months. Even though I was trying to recover from 15 years of back injuries, she was able to take me from total whimp to a regular class participant. I still modify all the workouts like Mel taught me, but I love seeing progress. All the people here are friendly and encouraging. Every single time I walk in, someone says hi and calls me by name. It's like Cheers, but healthier. ;)
