Dropped in to hit the last Open workout — what a great gym with super friendly staff! Nice setup, too, with several Olympic lifting platforms, a locker room, and showers. The other members were really friendly and encouraged others during the workout — a great community. Definitely dropping in again next time we’re in town.

I really like Crossfit 520, and if you are looking for a gym, you should definitely give it a try. The trainers are top notch and really care about us. The instruction is outstanding, the workouts are challenging and always changing so it never gets old. Everything can be scaled to meet any fitness level or ability, and the trainers are very good at giving you just the right amount of work. I was a bit nervous at first starting into something like Crossfit at 56 years old, but there was really no reason to be. Looking back now after a year and a half at the gym, I can assure you that there is no reason to be nervous. If you are on the fence about trying Crossfit, you should definitely come down and try it.Lastly, I cant say enough about the other members at this gym. They are nice, helpful, encouraging, friendly, happy, positive people that I love being around. It really is a privilege to work out with them, and best of all, it is fun.Update -- Ive been going to CrossFit 520 for 4 years now and Im still enjoying it. I think that says something too ...

Amazing workout! Super friendly and comfortable environment and I felt very welcome as soon as I stepped in the doors. Nice and clean facilities. The coaching was on point. I’ll be back! Thank you!!

Had my first weightlifting session with Stephanie yesterday. Great session. Fun to work with. Nice facilities. Cant wait to go back!

Ive been doing personal training with Emily at Crossfit 520 this past year and she is fabulous! Im 61 years old and in decent/better shape and Emily has made it so. She is so knowledgeable and careful. I have increased my strength, deepened my squats, and challenged myself in a safe and careful manner. Marcin and Emily at Crossfit 520 take extra time with their clients and make working out something to enjoy. Ive never felt better! Thank you!

Crossfit 520 is a phenomenal family of athletes working together to help each other reach their goals. Every day I look forward to working out with all of these amazing people. I drop in to other boxes when I travel and every time this experience confirms that Crossfit 520 is superior in their dedication to all of their athletes. Thank you!

Love my box! Ive been a long time gym goer at CF520 and I Cant express how encouraging Emily and Marcin have been as coaches. They definitely push you in reaching your full potential. Its not just a gym but a second home filled with crazy family members. :)

The community feel at CrossFit 520 is unlike any other gym I’ve been apart of. As a traveler, I’ve experience many boxes and drop-ins, and I can’t say enough good things about Marcin and the way he runs his gym. Some of the best programming paired with Marcin’s coaching style is a recipe for success in all aspects of life.

I have been working out at Crossfit 520 for 8 months and it has been the best exercise experience of my life. Marcin and Emily bend over backwards to provide excellent training, coaching, and encouragement for all members of their gym. They are highly motivated and skilled in both strength and conditioning and push their clients to achieve their personal bests on a daily basis. Ive visited 2 other Crossfit facilities in Tucson and Crossfit 520 provides the best overall experience I could imagine. The really amazing thing about Crossfit 520 is that Marcin and Emily have created a warm and accepting family atmosphere in their gym and they make the total experience fun! For my money, this is the best workout location in Tucson!

I have been going to Crossfit 520 for a little over a year and I love it!!!!!! Marcin and Emily are amazing people and trainers. I feel very comfortable when I go there, everybody is welcoming and very encouraging. It has changed my life and attitude towards working out. I have come a long way and I am looking forward to more to come!!!!! Training with Emily was a great way to get started and build my confidence. Thanks Marcin and Emily!!!!!

Just started my second year at Crossfit 520 and Im so thrilled! The trainers here know their stuff, the community is wonderful, and the owners are always listening to their members about ways to make improvements.

The expert trainers at Crossfit520 foster a welcoming atmosphere. They are able to modify the workout to your individual needs and limitations. Crossfit520 is not just a gym, its a family!!!!

Such a supportive environment. Great coaching. I cant recommend this place enough!

Im still new around Crossfit 520 but I love it here! I joined for just one month in December and I was a total newbie. Marcin and Emily were so gracious and encouraging even though I was anxious and uncomfortable. They know their stuff and they meet you where you are and the community is kind, encouraging, and interactive. Eight months later, I decided to start Crossfit again and there was no doubt which gym I wanted to join. Marcin and Emily made that decision so easy.

This past year at CrossFit 520 has been amazing. Marcin and Emily have done a great job helping me improve my lifts and increase my endurance. The CrossFit 520 staff is the most attentive of any I have experienced. Marcin shows up everyday with a helpful attitude. The entire staffs can-do attitude is very contagious. CrossFit 520 is the premier Crossfit gym in town.

My experience at CrossFit 520 has been absolutely amazing! I was a member at club in Tucson, however nothing was motivating to go! I checked out Crossfit 520 for a week and was hooked! There are members of all ages, I never feel uncomfortable and always feel supported! I look forward to hearing how others did in competitions or their plans from the weekend. We are a real family. If you think the members sound great you can only imagine how awesome the owners and coaches are! Emily is very knowledgeable and understands eactly how to achieve success! Coach Charlie works with you to improve something even slightly, that makes a world a difference in your lifting and Marcin!!! He doesnt stop on education! He is always learning to bring us the best at CrossFit 520! New workouts, stretches, builds relationships with other gyms and is well respected in the crossfit community! I came into this gym, starting 3 years in September. I have lost 30 pounds in total and am stronger than ever. I feel amazing! Come join us!

Ive been a lifelong athlete and recently came to Crossfit 520 after researching cross fit gyms in Tucson. A gym is like a family to me and i took my time to find the right one. The facilities are very clean and spacious and Emily and Marcin are extremely helpful. I was doing powerlifting and kettlebell workouts, including competing, for the past three years and was concerned about learning the crossfit movements. Marcin has scaled my workouts within the group class to enable me to learn at my own pace while being safe increasing the weights as Ive gotten stronger. I am very picky about where I work out and Crossfit 520 has been a great choice!

I live on the NW side of Tucson and although there may be a handful of gyms on my side of town I CHOOSE to commute 25 minutes every morning to be part of the crossfit 520 family. Emily and Marcin and are the heart and soul of our gym. The training is excellent! Marcin always ensures we are comfortable with the movements. Charlie focuses on technique and ensures we either maintain or improve on everything we do. The Crossfit 520 family has helped me accomplish things I thought were impossible. After having had 2 kids Ive finally learned to love my body and embrace the transformation. I could not be more proud to call crossfit 520 my home!

I moved back to Tucson from Seattle a handful of years ago, and it took me a really long time to find a local CrossFit gym that I loved as much as my beloved Seattle box. I finally found CrossFit 520, and I am so grateful! Marcin and Emily (and their amazing staff) have brought me so much joy. I have extensive life-long injuries from a previous snowboarding accident, and no matter what my restrictions, CrossFit 520 staff do not hesitate to make me feel welcome and create modifications that allow me to get equally intense workouts while also being completely safe and technically perfect. Even through pregnancy!...they found a way to work together with my health care team so that I could continue to work out and have a healthy pregnancy. To top it off, the comradery at this gym is sensational--the best Ive ever encountered! The CrossFit 520 team fosters the kind of environment that attracts phenomenal people, and I always know my cohort will be there for me. It makes working out fun--which is a huge motivator on days when that bed feels extra comfy! Thank you, CrossFit 520...working out with you is life-changing!

Top noch Crossfit establishment in Tucson! Its worth every penny.

Work out!

Love the atmosphere and trainers at Crossfit 520!
