Absolutely amazing staff and great programming Best CF gym in SD awesome location and all the equipment you need

I have been participating in Crossfit for 10 years and I am happy to say I have found my new home at ATR! The coaches are top-notch, the members are fun and dedicated, and I love the member events and competitions they host to bring the community together. I have sustained injuries and the coaches have been quick to accommodate and help me modify movements to allow myself to get a great workout without pain or further injury. I was also introduced the ATR's in-house physical therapist (Dr. Evan) and he helped me find long-term solutions to significantly alleviate my aggravated back; the pain is gone! Overall, this gym has everything you need for success and results. read more

CrossFit ATR - Me and my homie who dropped in! - Interval Training Gyms Near Me - San Diego, California

This is my 16th year of Crossfit. I've belonged to four different CF gyms in that time, and can say with 100% conviction that ATR is by far my favorite. The programming is great, all of the coaches are wonderful (they're knowledgeable, and care about the members success), both facilities are amazing, and the community is amazing. It's my "Happy place", and the best part is that in order to be in the best shape of my life - all I have to do is show up four days a week and work hard. No thinking involved - just follow the coaches instructions. HIGHLY RECOMMEND! read more

Great coaching, down to earth owner, fun group of people to work out with. No egos just a good time. Even if you're recovering from an injury, or feeling bleh, or the workout was just tough, you feel better having been part of the "fun". read more

Crossfit ATR is an amazing gym. I just moved from Los Angeles where I had been a member of 5 CrossFit gyms since 2014, and I was looking for new box. There are 8 gyms near my house and I tried all 8 and I chose Crossfit ATR because of their great coaching of showing form and fixing form, diverse community, great programming, and I just love the vibes! I think Adam the owner is the best owner I have ever met, he is really good at business. He makes everyone so happy, I am very impressed with his leadership. I made videos of my experience on rategyms on instagram, youtube, and tiktok. read more

Love this gym!! Great community and amazing trainers! The workouts are challenging but scalable for all fitness levels.

CrossFit ATR is hands down one of the most welcoming gyms in San Diego. Whether you're training at the Kearny Mesa facility or coming in from the Mission Valley area, the sense of community is immediate. The members are supportive, the environment is ego-free, and there is a genuine 'we're in this together' vibe. It's the perfect place for anyone who wants a tough workout without feeling intimidated read more

Best CrossFit gym out in SD by far. Great coaching, great environment, and a great facility. Highly recommend to any person who may be going for their first time or someone experienced. read more

You go to a gym like this for the community and coaches. And let me tell you, you won't get anything better in San Diego ! + their class times are awesome and flexible which makes my life as a parent so much easier ! read more

BEST GYM IN SD!!! don't waste ur time trying other crossfit gyms- been there done that. just come straight here I PROMISE YOU. thorough warm-ups, amazing coaches, close community, and the workouts have a perfect combination of a strength portion first and a WOD after. they even offer weightlifting classes 2x/wk which have improved my lifts SO MUCH! this place is no joke- i can't say enough good things. 10/10 recommend!!! read more

Awesome community and great workout programming. Only joined for a few months before moving out of California but wish I joined sooner!

Joining CrossFit ATR is one of the best decisions I have made! I joined about three months ago having never done CrossFit before. There have been many positive changes in my life because of ATR-I can't fully express them all here! The Foundations class is incredibly helpful in learning the basics from a private coach before joining group classes. The coach may shadow you in a group class or two as well based on what is needed. In addition, ATR offers private coaching for any level which you can do along with or instead of group classes (though group classes are so fun, I would do both!). There are also weightlifting classes great for extra practice with strength training. The personalized nutritional coaching I signed up for was a gamechanger in helping me view weight from a healthy lens and develop eating and cooking habits that can maintain a healthy lifestyle long-term. I have lost weight and gained strength. I am no longer pre-diabetic. More than all that, I fell in love with the act of doing CrossFit and how it makes me feel mentally and emotionally. I am more willing to try new things and fail and try again. Best of all is the amazing community of like-minded people and friendships I'm making. Everyone is trying to be their best selves and keeps each other accountable for reaching their goals while still laughing and having fun! read more

CrossFit ATR - Interval Training Gyms Near Me - San Diego, California

I started at ATR on a 10 pack over 2 months in September, trying to ease my way back into working out after a ~8 year dry spell. Figured it wasn't a scary "all-in" commitment and I'd gauge my interest. I was surprised how much I missed being in a supportive gym and found myself blasting through the 10 pack, well before October ended, resulting in fully committing...all-in. The community here is incredibly welcoming, which made me feel right at home. The coaches are knowledgeable, attentive, and always willing to help you improve, whether you're just starting out or pushing for new goals. Many class times, ample workout area, and I can always find parking! The workouts are always challenging but scalable, so you can adjust to your fitness level or the heavy lunch you might have incorrectly consumed a few hours earlier. I can't recommend CrossFit ATR enough--it's the perfect combo of tough training, great people, and a positive atmosphere! read more

Can't say enough great things about ATR, but here are a few things: 1. The coaches and staff are very knowledgeable and truly care about their members safety and their results. They are always actively coaching throughout the class and are quick to assist when needed! 2. The culture is extremely welcoming and serves multiple skill levels. I came in with some CrossFit experience, but never felt like this was a place that I "wasn't good enough" for. 3. As someone who likes to workout in the morning and go straight to work from the gym, it's great that the gym has 5 bathrooms with showers so I don't have to wait for a shower after my workout. Something you don't see in most CrossFit gyms or other group fitness studios. There are a ton of other great things, but you should come try a class and see it for yourself like I did! read more

4.5 This has been one of the least intimidating CrossFit gyms to walk into (in San Diego). Class sizes are small, the coaches are approachable and friendly, the programming is scalable and no one's yelling "no rep" at you, the equipment and gym space is continuously getting upgraded, it's always clean. Coaches and members are genuine and are eager to get to KNOW YOU and not just care about your results or PRs. There are kid friendly, parent friendly, and family oriented classes too--that alone can say a lot about a gym's values. Very glad I chose to try this gym instead of go where everyone else was telling me to go. P.S. if you're eager to smash the open, qualify for something, or compete--there are [more] competitive class times and multiple locations and all of the coaches are experienced and knowledgeable to push you towards those goals as well. just not MY tea right now but happy to know it can be if I want it to be. Dropped a 1/2 star because I just don't L-O-V-E love the programming yet. The open gym hours allow for me to supplement when I feel I'm missing something Though. read more

Top tier CrossFit facility with cool coaches! I traveled into SD before and CrossFit ATR is hands down the best box I've visited. Looking forward to visiting again! read more

CrossFit ATR is the best CrossFit Gym in San Diego! Great community and knowledgeable coaches. read more

This is not only about the gym, this is about community! I started my journey here October last year and this people already feel like family to me! Before coming here I had nothing to do with sport and been looking for place like this to change myself, my body and my mindset to become a better version of myself. I spent so much time looking for the best place and I found it! Amazing coaches, very knowledgeable and professional, incredible people at the gym, very supportive! I'm having an amazing time every class I'm coming to! Team is great! They will keep in touch with you and really cares about how do you feel. We definitely need more gatherings to get to know each other more and meet more and more amazing people! Thank you so much for all you do! You are AMAZING! read more

I started with ATR with some CrossFit knowledge but had never attended actual certified CrossFit classes. ATR made my transition very smooth. I had to unlearn all the bad habits and bad form from my prior gym but every single one of the trainers were there to help me. I could immediately tell they had the knowledge and patience to help me reach my goals. I am now lifting heavier than I ever have. And placed first in my first crossfit competition with plans on doing many more this year. The owner is awesome. He makes sure he knows everyone by name and comes around for a quick chat before the workouts if he's there during your class. Above all. The community has been amazing. They do a ton of stuff that makes this feel like more than just a gym you show up to and get your workout in. Competitions and holiday parties are an added plus that gets everyone familiar with everyone. I have found my gym and don't plan on leaving. read more

Did a drop in a few days while on vacation in San Diego and this place was great! People were fantastic, very welcoming and felt like family. Definitely would recommend! read more

CrossFit ATR - Interval Training Gyms Near Me - San Diego, California

I joined this gym three months ago without any clue about CrossFit--I just wanted to try something new and get in better shape. Fast forward two weeks, and I was hooked! The workouts are intense but so much fun, and what really blew me away was the amazing community. From day one, I felt welcomed and supported by both the coaches and fellow members (It was a Saturday team workout), who are always there to cheer you on and push you to be your best. Now, starting my mornings at CrossFit ATR has become my favorite part of the day. It's not just about getting stronger physically--it's also about feeling great mentally and being part of something bigger. I can't recommend this place enough for anyone looking to challenge themselves and have a blast doing it! read more

The best CrossFit in San Diego. the team was always prepared and willing to help us. ........ read more

Love the class time options. Easy to drop in, shower and make it to work. Instructors are tough, push you but also make sure you are safe and understand the movements. read more

I've been doing CrossFit for 1.5 years before my old gym closed. I did trials at 4-5 gyms in the area before deciding on CrossFit ATR. The new owner Adam is extremely friendly and responsive, and genuinely listens to members' feedback. The gym is spacious with lots of equipment and plenty of bathrooms/showers as well. Their workouts are also more challenging than other gyms I've tried and they really push you to be better than yesterday. The coaches are helpful and professional. Highly recommend! read more

Let me start by saying that I absolutely LOVE CrossFit ATR! I started working out here November of 2024 and ever since the first day I felt that this place was special and had a sense of community and camaraderie that I had never experienced before at any of my previous gyms. The coaches are extremely knowledgeable and always push me to reach my full potential while ensuring proper form and technique and make me feel like they truly care about my progress. I'm so glad that I found this place! read more

Joined Crossfit ATR A couple months ago, the coaches are super helpful and friendly. The program is amazing and the overall community is great read more

After being used to the regular gym routine. I was looking for a change. I found this studio and decided to stop by to get some information. Months went by before I finally took the time to check it out. I can't blame it on Covid since the studio was open! Any how, I ll be honest and admit that I should have started earlier. After taking a few tryout sessions with Tom and Stephanie, I was hooked! Why? The workouts change all the time. One is exposed to a nice variety of weights and cardio. Tom took the time to coach me while Stephanie was amazing in carefully reviewing the different movements in order to avoid injury. They are both outstanding coaches. I have to mention the team spirit of the studio. We all take time to encourage one another. It makes the workout session so much more fun. Price wise, this can't be compared to a regular gym. I feel like the difference shows in the quality of the workout. The class format is more like personalized classes. Just reduce the Starbucks weekly purchase and put the money into your workout. So, if you re looking for something challenging, give this studio a try. You won't regret it. read more

WOW....... Why did i take so long to review my Fitfam!! I'll keep it short and sweet and let FOMO kick in for y'all ;) Why you should consider CrossFit ATR your second home. *Great coaches - Coach/Owner Tom is such a great coach, keeps an eye on everyone and really focuses on helping every member with corrections, substitutions and advice. - Head coach Arturo is a hawk! He honestly sees EVERYTHING! Awesome coach and never lets you slack! He also coaches the barbell club and the weightlifting team! - Coach Stephanie is always killing a workout before coaching class and has so much energy while coaching that amps everyone (She has the best Jams). She's has an eye for form and offers great substitutions for WODS but doesn't let you slack! *Great WODS - From Clean and jerk, to rope climbs and Sled pushes, we do it all! *Quality equipment - everything's top-notch *Amazing brand spankin' new layout - The Box is Huge! 20ft rope climbs, over 12 racks, deadlift platform, 3 Olympic platforms - Amazing, sleek layout that was thoughtfully and functionally put together - New flooring throughout the gym (we got that new car scent) *Extras - Barbell club is included with CrossFit membership! - 5 individual restrooms each with private shower...

Seriously, get your glutes here and start lifting! Great gym with plenty of space, equipment, and programming for all of your goals. Coaches are friendly and supportive, especially helpful for that extra motivation in the early morning. ... but maybe the real gains were the friends we made along the way. read more

The ATR crew is bar none the best work out experience I have ever had. Highly trained coaches and good vibes all around!

Best Crossfit gym in San Diego. I've been to many different gyms in many different cities and Arturo is the best coach I've ever been instructed by. It's a clean gym with tons of equipment (including a sauna!). Adam, the owner, cares about the members and is constantly making upgrades. read more

I arrived at ATR through a recommendation from a friend, and the reception from the entire team was wonderful, I've been training there for 4 months and every day is a different workout, my life changed after I went to ATR, the encouragement is great but it all just depends from you. There will be no shortage of encouragement and if you still have questions, come take a free class and meet the people read more

After 3 months of being a member, I can truly say this CrossFit gym is one of the best things in my life right now! I have been involved in multiple different fitness related activities, but this place is my favorite. As someone who requires specific accommodations for my wrist, I really appreciate how the coaches do not hesitate to accommodate specific movements for me as well as check in to make sure I am not feeling any pain. The coaches also really push you to your goals! I would never imagine being where I am with my fitness if it wasn't for each coach motivating and encouraging me to continue or push harder. I love how the programs are always different, and fun! They are all doable, but challenging as well! In regards to scheduling, I love the 5AMs. As a morning person who goes to work at 8am and hates working out after work, being able to get my workout in early ensures that I do not have any excuses to skip. I would highly recommend this CrossFit gym for any experienced folks as well as those looking to get started. read more
