I'll be honest... I was pretty intimidated walking into Blk Box for the first time. But it didn't take long to realize that everyone there is genuinely supportive of you and treats you like family. A huge thank you to the people who've made such a difference in my journey.. Ryan, Dezi, Emily, Marco, Rachelle, and Victoria I'd been pretty sedentary for years, but Blk Box helped me build real strength and endurance, and I quickly got hooked to their gym and attending their classes. Although I have a ways to go, I'm in the best shape I've been in for a long time. So happy I found Blk Box! Highly recommend!! read more

I absolutely love Blk Box!! They have weight training and HIIT classes spread throughout the week with time slots that make attending inexcusable. The group environment is motivating and inspiring.

She leads by example. Highly recommend checking this gym out read more

HIGHLY RECOMMEND!! Blk Box Performance is exactly the type of training I was looking for. As a former professional athlete, doing 4 sets of 10-12 wasn't exciting anymore.

Phenomenal community of coaches and members. The camaraderie you build is second to none. Come give it try, you will not be disappointed. read more

I look forward to growing in my fitness journey and with Blk Box helping me reach new goals. read more

BEST GYM IN LOS AL AREA HANDS DOWN! Try a free class and you'll be hooked. Amazing community (owned by husband/wife duo) where members encourage each other and work hard. No two workouts are the same, and provide a challenge every day. As a former D1 NCAA athlete I struggled to find group classes that consistently challenged me. Blk Box does just that! All coaches - Ryan, Dez, Marco - incorporate functional mobility work into their workouts to keep your body moving correctly no matter your age or ability level. New equipment, concept machines, and variety of workout classes are just a few of the highlights. 10 stars for Blk Box. read more

BLK BOX is a solid boutique strength and conditioning studio for group fitness classes! On my first visit the staff warmly greeted me into the class while the instructor was so encouraging, engaged and attentive. Shout out to Emily for making me break a sweat as she empowered me to meet my goals. Cool and low key type of environment for the fit to the fresh - they welcome all fitness levels and will guide each individual along the way! Every class is different and focuses on different body parts so the programming never gets redundant. read more

Don't wait run!! Ryan and Dezi are so amazing they make you feel like part of the fam read more

So happy I joined BlkBox at the beginning of the year, I LOVE it! I am not a "gym" person and the boutique atmosphere here is exactly what I was looking for. The trainers are absolutely amazing...if I haven't been to class in a week they text me to sign up for classes and get going! They really care about your fitness/health journey and help you achieve your goals. I don't get bored of the workouts as they constantly change them up and add new fun things...like boxing and yoga on top of their regular strength and cardio classes. Been going for 9 months now and have never felt stronger! read more

Ryan and Desi are both super friendly and cool! Came in for a free class and signed up for unlimited classes at the end of the free session.

Blk Box is an amazing place and I highly recommend their services and group classes. It is a fun, non-judgmental, supportive, family like environment.

I took a class on a whim October 2024. At this time I was looking for a gym that had a strong sense of community. My first class was a Maxx conditioning with Dezi. I was hooked after that and took the other strength classes with Ryan and Marco. All of the trainers are great and knowledgeable. I highly recommend Blk Box so happy I found this place! read more

I've been training with Dez for almost 2 years now. I decided to dedicate some time to myself after being 5 months postpartum. Dez was there to help inspire and motivate me. I felt as instant connection to her not only from the similarities of our postpartum journey but because our her vulnerability and honesty. She didn't sugar coat anything about the mission we were about to go on together and held me accountable while maintaining compassion, a rare find! Dez is one of the strongest women I know and she gives you the space to grow and learn. In the time I've been training with her not only have a lost the weight but I've built the confidence I felt I lost after becoming a mother. I am looking forward to my continued journey with Dez and the new BLK Box performance gym! I hope my testimony serves as an inspiration for anyone hesitate to start their mission! You will no be disappointed. read more

This review is long overdue. I went through a period where working out was not a priority. I found BLK Box through instagram and was hesitant to try it out because of how long it hand been since. Best decision I made and have never looked back. The environment is so welcoming and everyone is always happy to help. I'm starting the nutrition journey with coach Dez and I am so excited to see long term results! read more

When I join a gym, I factor four things: How much is it going to cost me? What equipment is available to me? How are the coaches? and How is the environment? Now personally, BlkBox is the best there is. I've been a member for over a year and this is what I know: Most gyms cost an arm and a leg for a strength and conditioning membership. Not only is BlkBox affordable, all their equipment is available to you without breaking the bank at the other gyms. The coaches are all great. They have their different styles of coaching and they truly care about you reaching your fitness goals. They're knowledgeable and will correct your form if you're doing it wrong. The workouts are challenging and tough and it will kick your ass. But it's not too bad when you're around good people. The environment is all about that action. Get in, workout, get out. At the same time, I've met some pretty amazing people who push and support you and love to have fun in the process. I recommend this gym to everyone read more

I took my first free class a few months ago and It's one of the best decisions I've made! This gym gives you such a great variety of workouts. Ryan, Dez, Marco and Ray are very supportive coaches; they make each class challenging yet fun! They really take their time to get to know you on a more personal level, they understand your goals and give you what steps are needed to get you there. You can't beat this type of environment in any other gym. 10/10 recommend!! read more

I started training with Annabel at Black box and I kid you not, I've gone from weighing 189 to now weighing only 170 and I plan to keep on goin!!

I work at BLK box training. Highly skilled trainers.11132 los Alamitos blvd. Los Alamitos.

Where do I begin on why BLK BOX is the best gym ever... BLK BOX was a gym recommended to me for months by a friend. It took me a long time to pull the trigger. The fear of committing to something and failing... The fear of knowing my busy working mom schedule would be my daily excuse. But I contacted Coach Dez and she welcomed all of my questions and was so encouraging to just simply TRY. Her positive aura drew me in, and after my first class... I realized that positive energy radiated throughout every aspect of this gym. From the music... The members..... ALL of the coaches and the COMMUNITY ; simply amazing. This gym offers high intensity conditioning, full body strengthening, dripping sweat, calorie burning, and smiles all the way through the week. No matter the class you take you'll feel amazing. The classes are never the same, never allowing your body to feel complacent. Coach Dez, Coach Ryan and Coach Marco will keep you motivated, driven, and focused all while smiling, pushing yourself toward greatness and dedicating yourself to your best self mentally, physically and emotionally. This gym has truly changed my life and I couldn't be happier to show up everyday! These classes improved my strength, flexibility, mobility, agility, energy levels and so much more. Now my husband works out here too and my kids get to watch us take care of our health as a team. read more

Blk Box is an amazing place and I highly recommend their personal training services and group classes. It is a fun, non-judgmental, supportive, family like environment. All of the trainers are personable and treat you as part of their Blk Box family on your first day. Even the members in the group training classes are welcoming and supportive of each other, which I believe is due to the type of environment the trainers have created. The group classes are fun and challenging. I have been doing personal training with Desiree for 5 months and my experience has been nothing short of great. I appreciate her dedication and support on my wellness journey. She is very knowledgeable, kind, and motivating. I look forward to my sessions with her even when I'm having an off day. Like many people, I gained a decent amount of weight during Covid and struggled with getting in track. I lost about 9% body fat in my first 3.5 months of training here and gained a lot of muscle (without counting calories per my preference) I have received many compliments from others about my physical transformation and healthy eating habits Dez has helped me develop. When I'm having an off day, she is very encouraging and accommodating. She pushes me to my best potential and definitely keeps me accountable. She has made me enjoy maintaining a healthy lifestyle and I am now in this for the long run. Blk Box is great and you will be glad you joined. You will definitely see results. All of the trainers are truly amazing. They work with you and challenge you in a good way. read more

Highly recommend! Go in for your free class and I doubt it'll be your last. I started going to Blk Box's group classes a couple of months ago and I feel so much stronger, I'm able to challenge myself so much more and have overall more confidence. Go to Ty's class if you can-she demos the movements well, makes sure you're confident, she's so fun and her playlists are always on point. Her 7 o'clock classes are the best. The group quickly becomes easy to get along with which gives you the ability to light heavier and want to keep going back! read more

Love this place!!!! If your looking to get more motivated in your fitness journey this is definitely the gym to go to. You can reserve your own classes at what time you'd like from such as classes from 6AM - 9AM and classes from to 5PM - 7PM. The classes are an hour and super packed with a bunch of exercises that will definitely make you feel sore the next morning! Love the owners Desireé and Ryan they are super helpful and friendly and make you feel welcomed all the time. Super close to home so I don't dread coming here. Tons of equipment to use, and I'm just coming off of an injury and if there's an exercise I can't do they always help me figure out something to do that helps and always answer every question I have. Much love for the owners and the gym read more

For someone who was nervous about joining a gym because I feared collapsing once the workout started, Blkbox has become my happy place! Ryan, Dez, Marco, and Ray are amazing coaches who not only support you but push you in a way that is challenging AND (dare I say) FUN. I was worried about everyone else being worlds ahead of me during the workouts, but everyone is so encouraging that it creates a great sense of community. If you are someone like me who was on the fence about trying out Blkbox, do yourself a favor and go for it! read more
