O2 James Island is a clean, well equipped, and up to date full service fitness center. This center has so many great amenities and is one of the nicest fitness centers that I’ve ever visited. The locker rooms are clean, spacious and include a sitting area and a dry sauna. Space, Space ,Space . Did I mention the space? Even when there are lots of people working out you still feel like you have room to move. There are 3 group fitness rooms to accommodate the very diverse group class options. No need to move big equipment like bikes to make room for the next class. All of the equipment is up to date and well maintained. The long row of monitors suspended from the ceiling the length of the cardio area reminds me of a sports pub. :-) There are plenty of free weights,balls, kettle bells, other workout accessories available for use. I enjoy the training turf area on the main floor (it looks like a football field) and the outside area where I can flip tires and throw balls and not worry about bothering anyone. I travel between Charleston and NC so the multi facility membership keeps me on schedule with my goals. My favorite membership benefit is the guest/visitor pass. When my kids from out of town come to visit, we can all work out together.

I am loving my experience at O2! The classes are great, and the instructors are AWESOME. The sauna is the largest gym sauna I have seen and overall the facility is very clean. Highly recommend.

I love O2 Fitness, everyone is friendly and helpful. The yoga classes instructors are great and the classes are challenging and relaxing, too. The gym is clean and well taken care of. It’s only my second week, but I feel supported and motivated to keep visiting.

Great gym, lots of new equipment and didn't have to wait all all for anything. Has everything you'd expect, as well as ample barbell benches and racks. Staff are friendly and helpful.

Very happy with O2 Fitness on James Island. The layout is bright and open, and the vibe is always positive and welcoming. Has an upscale boutique fitness feeling, but with all the variety of a large gym. My husband and I went in thinking we would just do our own thing (we've both been long-time gym and fitness enthusiasts), but were impressed with the complimentary fitness assessment and committed to working with trainers. I've been working out with Liam twice a week (one-hour per) for about 6 weeks and have already made noticeable gains in strength, flexibility and muscle tone. I love that he mixes up the workouts, and always challenges me. I may, on occasion, whimper a bit, but I appreciate that he gently, but firmly, pushes me to keep going! At the end of the day, that's why I joined O2. I look forward to seeing where my fitness journey will take me.

I’m about 6 months into my membership with o2 and the James Island facility is awesome. Plenty of machines, free weights and cardio options. Friendly, helpful staff and the personal training program has me comfortable and confident with my fitness journey.

O2 Fitness in James Island is the perfect gym for me. The trainers are extremely personable and knowledgeable. Consulting with them doesn't feel transactional, they are just helpful. (Not all gyms feel this way from experience). I got the opportunity to sit down with Kat and she I got along so well I decided to ask for an independent-track training program. Her program is so detailed and I absolutely love it. I am able to utilize the whole gym and use machines I had previously never heard of. The layout of the gym is perfect for when I want to have a more isolated workout or be right in the thick of it. The large turf area is especially great for my variety of workouts. Very happy I took the leap and actually look forward to coming in for a workout each day.

O2 is 10/10 as a whole. Nick M is an awesome trainer. He’s been training me once a week for the last couple months and I look forward to it every week. He pushes you just enough. Take training sessions with him. You won’t regret it!

O2 fitness James island not only has been an awesome fitness experience but provides an amazing uplifting community as well, the 02 at West Ashley is nice but the James island location has a larger space to work with and all around better vibes, can’t recommend 02 enough!

Bella lights up my mornings when I don’t want to workout in the AM! So sweet & always there if I have a question! Definitely a keeper!! Friendly front desk staff is very important in the gym community! So thank you!!

Love everything about O2 on James Island, SC. It's the best gym I've ever belonged to. It is huge with tons of equipment, all kept clean and in excellent condition. Great classes (although my schedule only allows me to take one at the moment). The one my husband and I take is Vanessa yoga and it's awesome. We also both signed up for personal training and have been really happy with our experience. My trainer Kaely Thompson is so patient and helpful and really strives to find the best recovery exercises for me and my unique physical issues. She is great to work with and makes working out enjoyable! I highly recommend this gym!

I love my trainer, Leanne. And enjoy several of the classes. O2 Fitness is so clean and a pleasure to workout in such a great gym.

2 beautiful ladies at the front desk were so welcoming & wonderful! Shoutout to Julia🫶🏼 Ended up working out at both locations for free both mornings of my stay! Best “1st time at a gym” experience ever tbh!! If I ever move to the area you know I’ll be back! They even recommended the best smoothie place after! 10/10 staff, trainers & vibes!!

Great gym, well maintained & clean space, and a friendly staff. I mostly go for weight lifting, but I have also taken some yoga classes here too. They have a ton of machines and equipment, and I very rarely have to wait to use something. Also, it has a much more chill atmosphere than some other gyms in the area. I haven’t encountered any rude/obnoxious fellow weight lifters (but I don’t go at peak times so ymmv). Love this gym, super glad I made the switch.

Impressive gym. Very clean and spacious. Super friendly staff. Isabella gave me a great tour and patiently answered all of my questions. She was knowledgeable and thoroughly explained the many options for personal training, as that was my main interest.

Great clean experience. I transferred from another gym in the area. The only reason I’m not giving five stars is because it’s ALWAYS warm and not as cool as the other O2 in West Ashley and Golds. I’d appreciate if they lowered the temperature and change the flooring from carpeting to hard flooring in the locker room. Or shampoo it more often.

The absolute best gym I’ve ever been to! The staff is amazing and the facility is incredibly clean. The environment makes you actually want to go to the gym all the time. You will love your time here!

If you’re looking for a gym that’s serious about fitness, then 02 is the place. It’s not a shiny new gym, but it’s the place that considers its clients’ fitness goals a priority. The trainers are second to none when it comes to making sure you’re using the equipment right and that your form when exercising is correct. For those of you who have medical issues, the trainers are well versed in how to make sure you’re not hurting yourself while achieving your fitness goals. A special shout out to Nick, my trainer. He’s the best trainer I’ve ever had. I’ve been using a trainer for eight years now and didn’t realize how really bad most of them were. Nick has it all; the knowledge and the patience to ensure that a person is understanding each form and how to do it correctly. If this isn’t enough to convince you, then consider the fact that 02 has a PT on site that can help mitigate some of those nagging pains and aches. Kristen is both professional and friendly and more than willing to help get you back in the gym. Overall, 02 is the very best of gyms in the Charleston area.

Sierra is an excellent fitness trainer. She goes above and beyond in helping me reach my goals. She does a great job in explaining and showing how to do different exercises, so I feel confident doing them on my own. I’m so glad I found someone who encourages and supports me!

I've been going to O2 for a while now and it is hands down the best gym in Charleston! Having never had a personal trainer before, Dennis was very helpful when it came to expanding my workout routines. He is very patient and knowledgeable when it comes to exercises. I'm so glad I found O2 and my fitness has increased significantly since joining.

Erin truly runs an amazing club & the staff to back it! Bar none, the most hard working individuals at the gym, much respect & love to the entire O2 crew, from Chris, Steve, & Erin! You guys make this location the best! If anyone ever needs a true workout with good vibes & good times..O2 on James Island is the place to be! From their knowledgeable trainers to their friendly staff..

I am so glad I was recommended this gym. It is spacious, clean, comfortable. The environment is safe, friendly, respectful. The staff are very knowledgeable and eager to help when asked. The machines are well maintained, modern, easy to use, and there is instruction guides available for your phone if there is any confusion or you encounter a new machine you are unfamiliar with. Classes are fun and a just challenging enough, they make me feel great! There are many areas within the gym for any routine, to stretch, or cool down. Stephen is the best!

It’s been my home away from home for the last 2 years. I absolutely love everything about O2 on JI! The most amazing staff that always remember you, take the time to get to know you & the best trainers all around. Super friendly clientele & AMAZING, BRAND SPANKING NEW equipment. Love my am crew! Everything is always spotless and in great condition. HIGHLY recommend this amazing gym!

This is year two into my fitness journey and I’m sitting in the sauna right now an their is a sign that says if your on your phone mind leaving us a review & as a small business owner reviews are so important. - o2 changed my life. This is the best gym in the area. Great location. They’re super clean. The equipment is always ready to go. The staff is a 11/10- so friendly. Always have hair ties for me lol. If you need a gym I 10/10 recommend o2 to anyone an everyone. The members are also just as friendly so if your new to the gym world you will feel comfortable

I have been to a few gyms in a few cities. 02 is one of the best. The staff is friendly and always ready to assist. The club is very clean and that’s important to me. I tell everyone that wants to know where to workout to go to 02 and they will be happy. I have a few friends that moved here from up north and they have joined because I recommend it and they are happy. Nice job 02. Janet Shapiro.

I have been working out at O2 Fitness on James Island for a couple of years. It has been a joy working out at such a clean and well maintained health club. All of the employees are so helpful and knowledgeable. You feel they truly care about the members and it is not just a job for them. This attitude clearly starts with Erin the manager. Her cheerful attitude and great energy helps motivate the other employees. I highly recommend this club.

Awesome gym! Chris and Erin have a great staff. Phoebe is so nice at the front desk. Steve and the personal training team are one of the best I have seen. Great with clients and always interacting with members. Definitely the only option you should consider in the area.

I was visiting Charleston so I bought a week pass. Registration was super easy and fast. People there are very kind, this gym is very modern and extremely clean. The fitness classes are amazing with supportive and efficient coaches. Nothing to say except my experience was just perfect and I thank them for that. I will come back and sign up again next time I come for sure.

Being a travel nurse and trying to stay fit can be tough without the proper gym. I found O2 Fitness on James Island, while working an assignment in Charleston, and as soon as I walked in I was immediately welcomed and felt apart of the gym, as if I had been going there for a while. The equipment selection and quality is top notch, they had everything I needed and way more! It’s a very clean environment and well maintained. Lastly, the staff and trainers here are so supportive and encouraging! Loved working out here while I could, honestly wish I could take the gym with me to my next assignment, LOL! Highly recommend O2 Fitness Clubs, particularly this one in James Island.

A place where employees have taken the time to know me! Very friendly and accessible. They've expanded the space with new equipment and lots of room to spread out and workout. An excellent atmosphere for a personal exercise routine or to work out with a personal trainer! All are happy to answer questions about machines, routines or classes. There is even a physical therapist on site!!

If you are looking for a place that offers excellent amenities and ample space to get in a good workout O2 fitness is your place. If you are wanting to take your training to the next level then you need to book a session with Paige. Her knowledge and patience is second to none. She listens to what your goals are and then strategically designs a work out program to achieve your goals. Like most people who are just starting their fitness journey I was anxious about going to the gym and I didn’t even know what I should be doing. Just do yourself a favor and book a training package with Paige. That will be your greatest chance for success especially for someone who doesn’t have a fitness routine but wants to develop one.

Good equipment friendly staff! They are currently expanding the space with Olympic platforms, turf, etc, and I am very excited for it to finish! Definitely top notch gym for good gains! Also their classes are great too! I take the Body Balance class and it helps me so much with my mobility and flexibility!

A great gym with lots of equipment, lots of space and very friendly staff. My experience training with Paige has been fantastic - she’s super knowledgeable and accommodating, and her workouts make progress easy to see from week to week. Couldn’t recommend O2 and Paige more!

I love this gym. I’ve tried every gym in Charleston area and this one is by far the best. It’s clean, spacious, has new equipment, and the personal training staff is so amazing. Julia is a fantastic manager!! Classes are included with the membership which is amazing. Sauna in the bathroom is a huge plus!

Genuinely one of the best experiences I’ve had at a gym! Dennis is such an intuitive and creative trainer, and the Renew Physiotherapy team, Chloe and Kristen, have helped make my recovery and development go so smoothly. Love the O2 community!

O2 Fitness has been our favorite gym! Mario at the front desk always greets us with a smile and truly appreciates how your workout was. All around great guy. Also, the manager Chris is always so helpful and there for everything we need and always glad to see us! Just wanted anyone considering what gym to join, this is the one! Clean, and amazing staff!

I started going to O2 about one month ago and I've loved it so far! I used my 2 free personal training sessions with Sierra who taught me which of my muscles were underperforming and which ones were overcompensating. She was friendly and inviting and extremely knowledgeable about muscle groups and what machines/workouts are best for working each. I signed up to work with her 3 times per week and so far the experience has been fantastic! I'm excited to keep working with Sierra and learning how to improve my strength and endurance.

Nice, clean gym with tons of space and equipment. Awesome that you get 3 personal trainer sessions with a trial and then a follow up for progress if you want. Super friendly and helpful staff. Justin was a great trainer.

This gym is everything! It’s always super clean and has great equipment. The staff is all lovely! I had a consult and workout with Gio, who far exceeded my expectations! He is a highly knowledgeable trainer and makes you feel comfortable and confident in your abilities and what you can accomplish with the right mindset.

The employees are very welcoming and friendly!! The gym is very nice and has everything you need + there are a bunch of workout classes that come with the membership!! Definitely recommend joining!
