The best workout experience I’ve ever had.

I’ve been to a lot of gyms, but nothing compares to Onix. The structure of the classes is incredible, every workout feels intentional, balanced, and challenging in all the right ways. You can tell there’s real thought put into the programming so that you’re getting stronger, faster, and more confident each week.

The energy here is unreal, everyone from the front desk to the trainers makes you feel part of the community. I have to give a huge shout-out to AJ and Dre, my absolute favorite trainers. They bring such contagious energy, push you to your limits, and somehow make every class fun while still keeping form and safety a top priority. You leave their sessions drenched, smiling, and already wanting to come back the next day.

As Dre says "COME ONNN"

I am 51 years old. I have had an opportunity to experience strength and cardio training in many forms including a few years doing CrossFit. I am older than most (okay everyone?) at Onix - but I can not exaggerate how well designed the experience is. The core is the personality and knowledge of the instructors. What great recruiting by Onix! The aesthetics of the gym space is on point. I can’t think of a better way to focus, motivate, and enjoy my workout. There are some very fit people who are members or dropping in for a class. I am not one of them, yet I still feel welcome. It’s simple to modify weights/exercise that takes YOUR body to its edge for growth. On the other end my 20 year old niece who has not exercised since high school gym class went with me the other day and enjoyed it. If you want to get fit, you owe yourself taking a class at Onix.

I recently moved to the area and checked out a lot of different gyms before deciding to become a member here. A big draw for me was that they have programming and equipment that isn’t only cardio and dumbbells compared to other group fitness gyms I’ve been a member at in the past. As soon as I stepped through the door, I felt the good energy and positivity from not only the trainers & staff, but all of the other members working out here, so it was an easy choice! I’m already feeling more confident in the gym and am excited to keep coming back each time (:

Obsessed with this gym!! Been coming to Onix for 2 years and fell in love with this gym. The trainers are incredibly knowledgeable and work on form, technique, mobility, are, and endurance. Best gym for community, amazing workouts that burn, and recovery sessions (including cold plunge and sauna!)

Best fitness experience in LB especially if you wanna get yoked and not do the mental effort of figuring that out. All the coaches and members are super kind and encouraging. I was a former equinox member and I ended up liking Onix more!

Truly the best gym I could ask for! It’s like having a personal trainer but in a motivating group setting. Everyone is so kind and supportive, and the workouts are hard and rewarding. Couldn’t recommend more!

I’ve been coming to Onix for a full year now, and I can honestly say it’s one of the best decisions I’ve ever made. The trainers are knowledgeable, motivating, and genuinely care about your progress, it’s not just another gym; it’s a community that pushes you to be your best.

When I started, I was out of shape and struggling with consistency. One year later, I’m down 55 pounds, stronger than ever, and actually look forward to my workouts. The environment is supportive, the energy is real, and the results speak for themselves.

If you’re looking for a place that combines structure, accountability, and serious results — Onix Fitness is it. 💪

The coaches are really great here-especially Lo and Robin! The equipment is always kept very clean and organized. Overall, I have really enjoyed coming here over other gyms I’ve tried in the area. I like that they include more weightlifting into their programs rather than it primarily being cardio.

Been loving being a member of this gym. Also the programming that coach Aj has been providing. It pushes you each week. He really pays attention to his members and their movements. Cant wait for the next work out.

For some reason I am unable to leave a review on Class Pass, but I just wanted to share how much I LOVE this gym. All of the coaches have been truly wonderful, but today AJ went above and beyond to make it a great experience. I have been struggling with a lower back injury for nearly 6 months and before class I let him know that it was especially painful today, but I wanted to try and do as much as I could to work through my recovery. He was SO empathetic and understanding amidst my insecurity and frustration with the pain and limited mobility. Through the entire class, he made sure my form would not cause any additional harm and modified the moves so that I could still participate. He went above and beyond to make sure I was included and able to get my workout in. I am so grateful for coaches like AJ that meet people where they are and encourage them to keep going. Thank you, AJ!

DID YOU KNOW ONYX gives you strength???

Well so does ONIX (ha ha get it???) This gym is CHEF'S KISS to beginners and EVERYDAY LIFTERS.

You're like..ya ya..heard it before. But yes... this place accommodates ALL. From the person who's shy but wants to learn weights...but wont go to a gym cause its scary..to the I train 'LIKE ARNOLD.' (*insert Arnold voice)

If you, like I, have been around gyms forever...we all know there are GOOD pieces of equipment...and then there are WASTE OF SPACE and MONEY contraptions that sit in the corner that you swear one day you'll use.

This place...has GREAT EQUIPMENT!! Like...useful pieces that will ACTUALLY contribute to your functional movements (especially if you're getting older or sit all day for work).

Like...you'll hate cardio LESS here..cause they dont have you running forever (cough cough like some gyms) or have you pretending your burning calories JUST cause you saw sweat on your face.

There is GREAT STRUCTURE... programming and ACTUAL progression REGARDLESS of your training experience.

Every trainer is AWESOME... and every trainer trains differently. THIS ISNT BAD...it allows you to really find what you need and want.

But...lets be clear...EACH CLASS you're burning so many cals....training your endurance/stamina...and BUILDING MUSCLE (insert AVENGER THEME)

If you read this far... thanks. Truly...do yourself a favor…..and try a class. I bet on it...you'll leave feeling INCREDIBLE.

Onix Fitness is an elite training + recovery facility. While most gyms do the bare minimum, Onix Fitness goes above and beyond anything that's out there. It starts with the welcoming front desk staff followed by very knowledgeable trainers who are great at motivating you to push your limits while taking a class. All in all it's a great place to workout and recover. Highly recommend.

Great trainers who have deep knowledge in fitness and injury prevention as well as form. I’ve seen gains in my strength over the past 4 months and feel great after the sessions. Dedicating myself to this workout style has given me a sense of accomplishment and I’ve met good people who live locally! Excited for more!

Obsessed!!!! I was hesitant and a bit intimidated because strength and cardio fitness has always been a challenge for me..

I received one free class and now, I cant stop going!

I can lift with confidence and…. I CAN RUN!!!! That was always really hard for me because I just didn’t have endurance nor did any other gym or trainer help me actually achieve results.

Idk what the secret sauce is or how Onix has found such incredible people to run the gym, but I’m so beyond grateful for every one of them.

Try it out!!! & if you see a brown haired girl dancing to Lo’s and Robin’s jams or saying swear words During Ajs classes, it’s me! Come to say hi!! 👏🏼♥️

Great gym with great trainers and members! I won a free class for me and 15 friends from a social media contest. Coach AJ put together a tough and fun workout for my class. It also happened to be my birthday and AJ and the staff went the extra mile to make it special.

As someone who loves been to many gyms over the years, I can honestly say this is the best HIIT/strength group gym I’ve been to! The instructors are extremely knowledgeable & have PT certifications! The workouts are timed & they focus on a particular set of muscles leaving you sore… :)

This place is great. It’s like circuit training but with way better equipment than any other place. Full cages, barbells, and top notch cardio equip. The trainers are fun and full of energy, but also very helpful if u need help with the compound movements they have you doing! Can’t wait for the upstairs to open with the cutting edge recovery stuff 😁

This is like a country club experience for CrossFit. More cardio equipment. More equipment like a Bulgarian squat stand. The workouts are intense and effective. Nice balance of strength and cardio workout. A steam room and cold plunge are being installed in this month. The instructors are knowledgeable on the movement and help stir up the high energy.

Onix Fitness is an outstanding fitness facility. It has a variety of new equipment and it is clean inside. They have a multitude of class offerings. Jacob Richardson is an excellent exercise instructor. He is highly skilled. He is personable and nice. His class is fun! He is excellent at making things understandable for the class participants. The participants in his classes make great improvements. I would highly recommend Onix Fitness and Jake's classes. Onix Fitness is the best fitness studio on Second Street!

What an incredible gym! I took a class with Chris and he kicked my butt in the best way possible! He encouraged and pushed all of us to be the best of ourselves. Even when we didn't want to be lol. I'm not gonna lie, there were times where I wanted to quit but I didn't. I can't wait to keep going back! Not only did I enjoy the instructor Chris, but the entire staff. They were all so helpful and friendly! As well as a clean, modern and beautiful gym.

Newer to the Belmont Shore area and decided to visit Onix to check it out. Adam gave me a tour, so couldn’t be more excited for the opening. From fitness to recovery, they have it figured out & already one of the best gyms in Long Beach!

We stopped into Onix Fitness Long Beach this afternoon to see how the progress is coming along and to our pleasant surprise they are almost ready to open. I understand they will have some pretty amazing classes, but as a former athlete I’m really excited to use the recovery services that will be available for members. They will have Normatec compression sleeves (amazing), an infrared sauna, red light therapy and a cold plunge! If you’re in the area, stop by and get a tour with Adam(cool mustache guy) or one of his team members. Onix Fitness will be a welcomed addition to the Belmont Shore fitness community.

The owner seems to be so nice and very personable. Their prices are pretty competitive for the area with memberships around $150 per month for unlimited group classes. From my understanding they will have a large TV playing a workout and anyone who follows it will be provided with a heart monitor. The trainers will walk around to ensure customizable workouts and help modify the group type of exercise to your individual need.

So if you're into workouts following the instructions on a large screen and having trainers customize parts of it for you PLUS having unlimited access to it for around $150 per month - this is the new gym for you!

Ohhh...and the best part - they will have a recovery area with a sauna and a few other relaxing things! This sound sooooo good!
