I've been going to 3D Fitness 4-5x/week for the past three years -- including all the way through my first pregnancy -- and it's easily one of the best decisions I've made. The workouts are strong, but that's not the differentiator. The community is. You see the same people consistently, and over time it becomes a tight, supportive group. It's rare to find a gym where you actually look forward to who's going to be there, not just what's programmed. Programming is thoughtful and well-balanced -- strength + high-intensity cardio -- and it never gets stale. Chris (owner/instructor) is especially good at reading people and pushing you just past where you think your limit is. You end up doing more than you expected, regularly. There's also real connection beyond the floor. They organize occasional events -- I recently did a cooking class with ~20 women from the gym -- and it adds another layer to the experience. I've always been active, but this is the first time in 20+ years I've been this consistent. That's not accidental -- it's because of the environment. If you want a place that will push you, keep you accountable, and make you want to show up, this is it. read more

Love coming here! Been coming since September 2025, and it's exceeded all expectations for this 50+ year old who's never been able to commit to a gym (and wasted so much in membership fees!) in her life. Owners Chris and Nancy are so welcoming, professional, and reliable. Plus super clean. Hours are perfect for working peeps. Vibe is friendly and chill. Chris designs the workout with such variety every session, it never gets boring. And so satisfying to see my progress over time, helps me feel good knowing I'm doing something really important for my health. Did a Mud Run in Irvine last weekend with my 26 year old daughter who got tired before I did. Highly highly recommend this gym to anyone who wants to get healthier and aims to stay that way. read more

I've been a member of 3D Fitness for 7 years now, and it continues to impress me every single day. What keeps me coming back is the incredible variety in the programming. I love walking into the gym not knowing what to expect, and being surprised by a new challenge each time. It keeps things fresh, fun, and far from boring--even after all these years! They've also added some new equipment, which has taken the workouts to another level--more dynamic, more engaging, and definitely more effective. The thought and creativity put into each class really show. This place isn't just a gym--it's a community and a source of daily motivation for both physical and mental health. Highly recommend to anyone looking for a fitness routine that keeps you on your toes. read more

I love this gym for so many reasons! They are open 7days a week with a variety of class times, they're close to a Tesla charging station, and small classes capped at 12 people. The owners are amazing and the gym feels like family. read more

3D Fitness has it all! Circuit training, small group, HIIT, weight and cardio. Best of all, the best members to carry you through a tough workout. I love that I can push myself or go at my own pace, and the workouts are so different. They have a rower, versa climber, ski, bike, and other machines that make the workout different every time. It been 8 years, and I'm still looking forward to my next class! read more

My wife and I love going to 3D Fitness. Each workout is different and even though it looks like a lot of sets, options are given for different capacities.

If you're looking for a small group setting within a no judgment zone, 3D Fitness is the perfect gym. read more

I had to add an updated review since we've been at 3D Fitness with Chris and Nancy for almost 4 years now. We've never been as fit as we feel now -- and for being in our early 70's, that's saying a lot. But the thing about 3D is not just the gym experience - even though that's great. It's the relationship, the sense of community and belonging that matters even more. Chris is our trainer and he's super fun, encouraging, and knowledgeable. There are plenty of gyms out there, but 3D Fitness is unique in the personal and communal experience, as well as in the individualized attention and encouragement. Highly recommend. You will never dread the gym again!! read more

Best workouts in Irvine! Always gotta come to the challenge Saturday You will never be disappointed coming in every day. read more

3D Fitness - Trainers Near Me - Tustin, California

3d fitness is a top notch gym on all aspects. The trainers (Chris and Nancy) are incredible. You have a new workout everyday and they cater to your individual condition. They take the time to understand your strengths/weaknesses to really help you accomplish your goals. The equipment is all brand new/top tier condition. I highly recommend 3d Fitness. read more

I have been going to 3D fitness for 3months now. Since I started, I feel more energetic, motivated and happy!! The vibe at this gym is amazing that I just can't stop going. It became my morning routine that I feel missing something if I can't go. Chris and Nancy are amazing people as well as amazing trainer! All the people who come to this gym are very motivative, helpful and kind!! I just love the environment. I am proud of myself that I found 3D fitness and decided to go! I am very happy to meet the great people and work out together :) read more

Love 3D Fitness! Been going strong for six months now and plan on continuing to go consistently. It's become a part of our morning routine and it doesn't feel complete without it. The owners and trainers, Chris and Nancy, are so welcoming, supportive, and truly genuine and kind! Every day has a different workout set up, which makes each day fun and interesting! It's a well-rounded workout that includes weights, different machines, cardio, etc. and you finish with a two minute plank. I never knew how hard you could work out in 45 minutes. You leave each class feeling accomplished. You can go at your own pace, which makes it very doable, and you can challenge yourself as well. It's also nice that it's a boutique gym, with 12 people max per class, which creates an amazing community. Some members we've met have been coming since day one and continue to do so many years later! They have great day and time selections for classes, which you can easily book online, and they also have team challenges on Saturdays. If you're thinking about it, just do it! Check out their trial classes. They have incredible before and after photos that show results and it's great for beginners or wherever you are in your fitness journey. 10/10 recommend! read more

Love this place! Best part is these are short 45 min classes to get in and out. Everyone is so nice and supportive, even for beginners. Highly recommend! read more

My wife and I love this place. We've been going here since Jan 1st, and have had only amazing workouts. Every single time we go its different and never gets boring. The instructors are really amazing, and are super supportive. We're learning at our own pace and getting stronger every day. We've made good friends here and don't plan on stopping anytime soon. Don't be afraid to come in on your first day, it's extremely welcoming, and everyone goes at their own pace. I know it can feel daunting, but don't even worry about it for one second, just go! It doesn't matter where you are at in your fitness journey, we'd highly recommend taking the first step and coming in! Nothing is more important than our health, and this is the place to do it! read more

Chris and Nancy have built something special here. There is a strong sense of committed and support from not only the owners but all. If you're looking for a great always changing workout that keeps you motivated and inspired look no further. I'd highly recommend you trying out 3D, trust me you won't regret it. read more

So happy I found this boutique fitness gym by my house after moving to Irvine. Nancy and Chris really welcome you into their fitness studio and it is a very supportive and encouraging environment. Classes are designed as a circuit training style workout in 45 minutes, and every class is different and utilizes a variety of machines, weights, cardio, etc. Max. Is 12 people per class so I enjoy the small size. I love their online scheduling which makes it very easy to book a class too. Try it out- you won't regret it! read more

Let me start off by saying that I HATE going to the gym. But with 3D Fitness, I don't dread going to the gym. Chris and Nancy are so kind and even though I'm a dummy with gym equipment and exercises, they are always so helpful and check up on me and ask if I'm doing ok. You don't get that level of attention from any gym unless you get a personal trainer. I love that the exercises are dynamic and change daily, and it can be for any level so I can do what is appropriate for my health and level of fitness. They will never push you to go beyond what you are comfortable with, and are kind enough to show you alternatives if you can't do a certain exercise. Their schedule and availability are great too. I left a gym that was super affordable ($25 a month) and came to 3D Fitness, and now I am actually going to the gym and looking forward to it. read more

This is such a great gym! The classes are friendly and effective. Chris does an excellent job coming up with efficient workouts and makes them a lot of fun while we work really hard. I have lost 50 pounds from April to December and I am 52 years old. If Chris can help me make such a dynamic change in my health, he for SURE can help you too! read more

I absolutely loved my experience at 3D Fitness. I am often intimidated to walk in to a gym for the first time and Nancy (the owner) put me at ease right away. I instantly felt comfortable. She greeted every single person by their name as they entered the gym. The members were all friendly and welcoming. Nancy instructed me on each circuit and made sure I had the correct form. I was so impressed by their high quality equipment. They have Versa Climbers and Ski Ergs. The variety of the exercises kept the class interesting and dare I say FUN! This was the most effective workout I have experienced! I am so happy I found this gem of a gym!! read more

3D Fitness - Trainers Near Me - Tustin, California

A true place of meditation after a long and stressful day at work! I was recommended by 2 of my closest friends to check out 3d. For about 8 years I have been off a regular workout routine and my wife and I have been dealing with the challenges of finding time with raising our two boys. I have now been with 3d for 3 months and absolutely love it here! Chris and Nancy are truly kind people and run a different workout every single day. The workouts are primarily split into two categories - hiit cardio and weight lifting. If you run their program from mon-fri you will hit all major muscle groups from top to bottom and also have had a wonderful and challenging hiit routine, which is great for burning fat. Every single workout gets you in and out in 45 minutes or 0.032% of a day! Its fast and you'll be out quick feeling great about yourself for the rest of the day. If you have any curiosity of trying 3d out, you really can't go wrong with running their 2 week trial. read more

One of many reasons why I love this place the class size are small, there are no more than 12 people per class which is nice because we can really focus on technique and form. They also have lots of class through the day as well as the weekend. A big plus they clean all the equipment after every class! read more

I've been going to 3D Fitness for about 6 months. We found this by researching online and I must say, the reviews are spot-on. It's a small, husband/wife-run business and they are always super personal and greets you by your first name as soon as you enter. Classes are small and you never know what you're going to get when you walk in there as Chris cooks up a new routine every day. Fitness is their passion and it shows! Classes are a bit on the expensive side unless you get a monthly unlimited pass (a pack of 10 classes costs $31 per class for a 45-minute session), but class size is very small and I think it's worth it knowing I support a small, no-nonsense business run by people who really care. I use this fitness as injury prevention after my main sport, but as a bonus, I have lost a few pounds with these HIIT-style classes. Thanks, Chris & Nancy! :) read more

I've been going to this gym since I was around 8 months pregnant with my daughter. She's now 1 and I'm so glad to be back. Chris and Nancy are great people and trainers. The classes are 45 minutes but you get so much out of them. It's like a mini Orange Theory but with friendly motivational people surrounding you. Highly recommend this gym. read more

10/10 recommended for beginners like me who knows nothing about work out. 45 min small group training with Chris/Nancy. They will really take care of you and guide you about how to do everything right instead getting hurt. More intense compare to wandering in the gym, and more affordable compared to personal training. Working out is hard but I do feel full of energy for the rest of the day. read more

3D Fitness delivers top-notch workouts that masterfully combine functional core strength, cardio, and HIIT. Chris and Nancy have created an amazing atmosphere both welcoming and motivating. They really focus on getting to know you personally and your fitness goals. I always look forward to my workouts with them. If you're looking for a boutique gym that excels in delivering results and community, 3D Fitness is the place to be. read more

When I first went into 3D fitness, I was 4 months postpartum and I felt totally out of shape. Chris is the best trainer ever. He is very knowledgeable, patient and postindustrial all the time. Nancy makes 3D feel like a big family. Whether you wanna get back to your workout routine, or you have never worked out before and want to give it a try, 3D is definitely the place to go. It's a healthy life style you can choose. read more

I started going to 3D Fitness towards the end of July 2023 as someone who hadn't exercised regularly for a couple years, didn't like or have the knowledge to plan my routine properly for the day, and lacked the motivation to go to the gym or even push myself when I got there since I gym by myself. I was looking for a class that could solve those problems, and 3D Fitness was perfect for me. The classes are 45 minutes of HIIT exercises that will guarantee to have you winded and sweating by the end of it, and you'll feel proud to have "survived" the session. The classes are small (4-12 people depending on the time and day) so you get individual attention from Nancy or Chris, and everyone is focused on what they're doing which creates this no judgement, productive atmosphere of people working out hard to finish the circuits which are different each day. As someone who's felt gym intimidation before, I never felt bad for not being able to keep up because everyone is nice and understands what it's like to start. In a way, it's very motivating to see others who've been going to the class for a while crush circuits because you'll know you can get there with consistency. This is honestly a gem of a gym, and I highly recommend going here if you're looking for a time-effective class led by the nicest trainers who motivate you when needed. read more

UPDATE after almost 2 years of 3D Fitness: At 48 years old, I'm in the best shape of my life! And I've completed a marathon, a century bike ride and a few triathlons, played volleyball for decades, done years of bootcamps, yoga, pilates, Beachbody workouts (Insanity and Asylum), etc. I come to 3D almost daily, and thanks to that 45 minutes, I have muscles I've never had before, including those elusive post-baby abs! Even better than the results are the friendships at 3D--for the 1st time in my life, I actually look forward to coming to the gym! read more

3D Fitness - Trainers Near Me - Tustin, California

My wife and I love 3D fitness because every time we go, we feel like we get the most intense workouts in the least amount of time. The movements are not intimidating or difficult to learn, but they are challenging enough that you will definitely feel the burn. When we look at our Apple Watch at the end of the workouts, we burn sometimes 600-800 calories in 45 minutes. I've put on some pounds since the pandemic and from being a new dad, and since I've been gone back to 3D fitness the last couple of weeks, I've made great progress in shedding a few pounds already! I will also note that the owners, Nancy and Chris, are just wonderful, supportive coaches and just overall great people that really care about every person that walks through the door. They take the time to get to know everyone and build a strong, friendly community. And I feel proud to be part of it. I highly recommend 3D fitness! read more

I was hooked at my FIRST workout session!! When I stepped into the studio, Chris immediately greeted me with his warm smile and introduce me to all the members. I felt that I was welcomed by them. People at 3D fitness are so nice; I got a workout partner right away. Chris and Nancy are professional. During the workout, they would correct your form and provide proper movement instructions. I was just done my second session this morning and I really enjoyed it. read more

LOVE LOVE LOVE this place! I wish I could give 6 stars. Absolutely the best work out around, huge results, value for money, and caring atmosphere. Members feel like family. Husband and wife owners Nancy and Chris work so hard for their gym family. I have had innumerable experiences with gym memberships and personal trainers, sometimes at many times the cost of 3D. None can compare. Seriously, do yourself a favor and check this place out! read more

Best local gym in the area. Since the lockdowns began, I was a little hesitant about returning to a gym, but Nancy and Chris have put that insecurity to rest, we frequent cleanings, smaller classes, and outdoor training. This is not your normal box gym; it is a highly focused and efficient personalized workout experience. If you do not want to squander time at a gym, trying to figure out what to do next, I highly recommend checking out 3D Fitness. Nancy and Chris run every class with passion and are frequently motivating everyone to push it to their max! Workouts are carefully curated each day and no day is ever the same. I've been going to 3D Fitness for over a year, and it's still fresh. Not to mention the personal attention they provide here is top notch, I have a back impediment and they are also helping me modify exercises. Everyone is fantastic and friendly, from the trainers to the gym-goers. read more

So glad I joined this gym! I've been coming to 3D Fitness for about 5 months now, and it has become one of the best decisions I've ever made! I always struggled finding a gym that I felt comfortable in and had motivation to go to, but here at 3D Fitness I look forward to every session. Chris and Nancy are so incredibly welcoming, and everyone is so friendly and willing to help you out. This was the perfect fit for me: I come in, complete the designed workout for the day and leave feeling tired but accomplished. I don't have to worry about creating my own workout routine, and everyday is something different. A great combo and balance of using weights and cardio. Sessions have now become part of my routine and I'm feeling great! read more

Well...here we are almost a year after my first review and I have to say, everything I said before still holds true. 3D Fitness isn't just a gym, it's a family of people focused on the same goal, getting fit and healthy. Chris and Nancy are absolutely amazing and have been a huge support system for me on my fitness journey. It's hard to believe I'm only months away from my 2 year anniversary. I've met some amazing people who are not only my workout partners, but my friends. If you are looking for a place to workout that is more than just a gym, where you are going to feel like a part of something bigger and better, join 3D Fitness and become part of our fit family! read more

3D Fitness - Trainers Near Me - Tustin, California

3d is the best! If you want a serious workout that will get you fit in 45 minutes at a time with some super great people - Go here! You push yourself at your own pace and you will definitely find yourself pushing harder to be your best! read more

My husband and I joined 3D Fitness earlier this year in our search to find a studio that catered to both of our workout preferences. I tend to gravitate more towards moderate strength training, spin and pilates-type classes while he enjoys more of a Crossfit-style workout and 3D Fitness was the perfect mix of all of those things for us. The 45 minute circuit training classes are challenging, effective and can be scaled for all ages and fitness levels. The vast age range of members in their 20s to their 50s is a testament to this. We've never once repeated the same workout as Chris and Nancy (husband and wife duo) are super creative and constantly change up the routine from day to day. Equipment is also top-notch which shows they value quality - they have Versa Climbers, Concept 2 Rowers and Ski Ergs and Airdyne Bikes just to name a few. We always leave class drenched in sweat, feeling majorly accomplished and excited to return for another round. We initially joined with just one goal in mind: to spend more time together after work while attempting to get into better shape. We were able to accomplish that goal but got even more than expected by entering into such a warm and welcoming environment created by Chris, Nancy and their loyal members. Many of their members have been coming here consistently for years and have formed close friendships as a result, which speaks volumes to the community that Chris and Nancy have built here. In a city like Irvine, that community feel can be hard to find and we're so glad we stumbled upon this one at 3D Fitness. If you are even remotely interested in getting your sweat on in one of the friendliest, most welcoming studios in town, I highly recommend checking out 3D Fitness - your first class is free! read more
