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.

There are a LOT of Crossfit gyms in Tucson. I dropped in here and they were very responsive and welcoming. We ran through a good warm up, and sections for the day that were challenging and fit together into a thought-out program. The coach was experienced, and they seemed to have a decent group of experienced athletes. Certainly, a good place to drop in, if you are in Tucson.

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!

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.

Amazing environment, no body puts people down because they aren't as in shape or strong. Constant support and encouragement to help push yourself farther then you thought you could ever go. Knowledgeable coaches who are proficient in what they do. They help instill correct form in all the athletes, self confidence, and to be the very best you can be in the weight room.

You know how you can look back on your life and pick out defining moments where you knew your life was forever changed? Maybe it’s starting a new job, or having a baby, or moving to a new city…? I had one of those life-changing moments just over a year ago when I was introduced to Melissa and Matt and CrossFit 646. I started off Personal Training with Mel at the recommendation of friend, and eventually started taking their CrossFit classes. It's around that point my life forever changed for the better. Prior to finding 646, I was a Cardio Class Queen, both taking and instructing cardio classes nearly 5 times a week. Little did I know then how much more there was to fitness!

I was incredibly hesitant to start CrossFit classes. I was concerned I wouldn’t be good enough, I wouldn’t fit in, and that I would have to defend my participation against the “CrossFit Stigma” that so many people have. But here’s what I found:

- Everyone is good enough! Matt, Mel and team find ways to accommodate all levels of skill, fitness, goals, injury and motivation. Just because I started slower, lifted lighter, or rested longer than others in the class didn’t make my workouts any less beneficial. In fact, starting light and slow allowed my body to adapt to changes and discover strength I never knew I had! And over the past year, I have found myself celebrating finishing a tough workout, being able to do something I never could do before, and hitting personal records.

- Everyone fits in! I’ve never seen a more diverse group of people with the goal of getting in a good workout. Some folks do their classes twice a week, others are at the gym daily, and some have long term competition goals and are in the gym all the time. But no matter what, everyone is supportive of each other. There’s nothing better than the cheers and high fives from everyone during and after completing a killer workout. It’s like a high, and once you feel it, you never really want to let it go.

- The CrossFit Stigma doesn’t matter! I, myself, used to make fun of CrossFitters; but I know now it’s just because I didn’t really understand it. And now, after doing it, I really don’t care what anyone thinks of me or my participation in CrossFit. These workouts challenge me. The people excite me. And being a part of this family makes me happy.

If you’re looking for a place where you can be challenged, meet great people, and get in shape, you certainly will not be disappointed with CrossFit 646. I guarantee that once you try it, you’ll never, ever look back. You too, will be talking about one of your life’s defining moments.

Best gym ever. Thanks Matt and Melissa for being patient, changing my workouts and for curing my injured tendontis with the voodoo band. Your positive attitude and joy for being "fit" is great inspiration for all of us. It's been fun seeing your gym membership grow.

Matt and Mel are two of the best coaches I have ever personally worked with. They are incredible at teaching technique and keeping their members as injury free as possible. The members are very inviting and so many other positives that you just have to experience for yourself. Drop in and you will see exactly what I'm talking about 😀

These guys are not just trainers. These guys are also teachers. I've had trainers in the past but these guys are better both technically and personally. Drop in on one of their classes; I think for free too.

The Sweet & Short of Crossfit 646:

Matt & Mel run an amazing crossfit box! I started going to the gym in October of 2015 and have gone consistently 6 days a week since. I would recommend it to anyone who is interested in becoming fit and feeling challenged in a welcoming atmosphere. All of the coaches at Crossfit 646 are friendly, helpful, understanding and find time to coach you one-on-one during their small classes. Every one here is supportive of one another and looking to do the same thing: get healthier, stronger, and better! Definitely try out one of their classes, the first one is free so you've got nothing to lose!

The Long Version:

When I first started college in August of 2011, I joined the University of Arizona's Women's Rugby Team. It was team oriented, full-contact, and awesomely fun! I loved the sense of community I felt there and no other sport had motivated me as much. In my last semester of my undergrad, I had to quit rugby in order to work more. The next 10 months I tried all sorts of ways to stay in shape, but I wasn't committed to anything as much as I had been to rugby.

Finally in October or 2015, I joined Crossfit 646. When I started at the gym, I felt tired and aggravated by things that would not typically bother me because my body was trying to let me know that the sedentary lifestyle I had started to make my routine was not working out. At first I was winded after any little bit of exercise and could only lift light weights, very clumsily I might add. Now, I'm doing things I never imagined I would: burpees, wall balls, thrusters, kettle bell swings, you name it! And if I haven't done an exercise, I'll scale it until I can!

Matt, Mel, and Camille have been extremely supportive and helpful whether it be giving me tips during a class to better my form or talking with me after class about things to help my mobility or diet. Over the last three and a half months I have seen huge improvements in my physical and mental well-being. Crossfit 646 is the best crossfit box in Tucson, go check it out!

There's not enough good things to say about this place. Matt and Melissa are wonderful trainers who are very passionate about their work. They are very knowledgeable and excellent instructors, always ensuring that everyone knows how to perform the workouts in a safe and correct manner. The atmosphere at this gym is one of my favorite things. Everyone is very kind and friendly. Matt and Melissa are also really good at adjusting the workouts to your level of fitness, making them challenging enough, but not too overwhelming. I highly recommend this place.

I am an "older" person....... okay I'm 60. I had to have some medical stuff happen and was in Tucson for the weekdays end of Sept Oct and begin of Nov. These guys kept me fit and able to "fight" the medical stuff. I will say this is cross fit. so you need to be ready to put out the BTUs (British Thermal Units). I came in being able to do pull ups and pushups. These guys can get you doing and keep you doing. You just need to walk through the door.

The place is clean, a good, light, airy, feeling, they have enough equipment so you wont' have to go looking. they also have classes that will pretty much accommodate your schedule. Go get healthy!!!!

Matt and Melissa York valiantly embraced the challenge when I lumbered into CrossFit 646 with a flabby 48-year-old body that hadn't been to a gym in forever. I was coming to them with noticeably closed-shouldered, slouched posture that had atrophied from years of computer work in the cubicle world.

Through boundless encouragement and amazingly patient coaching during their daily group workouts -- always with a keen eye on my safety -- Matt and Mel delivered me from my unfitness.

First, it was a challenge for me just getting through their arduous repertoires. Then, my strength and fitness blossomed. Even my posture improved. (Walking upright and balanced has given me a glorious new perspective on the world!)

What would have seemed crazy to my former, sedentary self, Matt and Mel's workouts are fun for me now. Bring on those weighty exercises! I have never felt better and credit Matt and Mel's kindness, warmth, inspiration and expertise for changing my life for the better. I am so grateful to them!

Of course, just as awesome is the friendly and phenomenally supportive community at CrossFit 646! I hope to be a member for the rest of my transformed-for-the-better, walking upright life.

The best CrossFit gym in southern Arizona by far. Matt and Melissa both have an extremely vast amount of knowledge about how the body works and how to live a healthy lifestyle. The gym is always clean, the equipment is the absolute best on the market and everyone is super friendly and not intimidating. The workout programming is great for anyone who wants to compete or for someone who just wants to be fit and feel better. The coaching and instructing is a main focus and all movements are performed with the utmost safety in mind. Matt and Melissa have both been coaching a long time and know how to push someone outside their comfort zone or when to scale things down a bit. Your health and safety is their main concern. If you're on the fence about CrossFit or little afraid just come try a class and I guarantee you'll be hooked.

Crossfit 646 is a great place to work out! I moved from the east coast and Mel and Matt have done nothing but encourage, uplift, educated and kick my butt with EVERY workout! They keep in contact with you every time you miss a session and are truly concerned about YOU, your progress and your everyday struggles. I know I wouldn't be happier at any other crossfit here and I glad to call this box mine! If you are looking to change your life with owners that really care about you all while sweating your butt off, dropping pounds, building muscle, getting fit, having fun, and changing your life then I have no doubt that you'd be a great fit to this Crossfit family!

Crossfit 646 is a friendly, welcoming and fun environment to workout in. After training with Matt and Mel from 646 for just over 9 months I can confidently say that they are the best trainers I have ever had. The classes are always a good time with lots of amazing athletes but safety is also accounted for. Matt and Mel have the knowledge and skills needed in order to help anyone start being more active. I wouldn’t trade my 646 family for anything :)
