I've been going to 3D Fitness 4-5x/week for the past three years -- including all the way through…read moremy 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.

I've been a member of 3D Fitness for 7 years now, and it continues to impress me every single day…read more 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.

I started my fitness journey at F45 Tustin a little over a year ago in 2025, and I can confidently…read moresay that it has been one of the best decisions I have made. The results speak for themselves. The physical changes are noticeable, but more importantly, the consistency, energy, and overall mindset shift have been just as impactful. What truly sets this location apart is the coaching staff and the community. The coaches strike the perfect balance between motivating, encouraging, and keeping things fun (even during the toughest sets). They push you when you need it, support you when struggling, and genuinely care about your progress. Equally important is the community. What started as a group of people working out together has naturally evolved into real friendships. That kind of environment is rare and important to me. If it were not for the great people here, I would have stuck with my other Fitness membership. Speaking of which, in full transparency - I still have another fitness membership elsewhere. However, I have not touched it in months. If one is looking for a place that delivers results, keeps you engaged, and surrounds you with the right people - this F45 Tustin location is the place to be.

They have many class options but they do seem to get busy because they're waitlisted on the app. I managed to passport one Saturday morning. I liked the trainers, the vibe and the music. The DJ arrived for the class after mine so I missed out on that but I still liked the music. I noticed the gym was air conditioned which was different to mine. The instructor's were great at walking around and giving you tips on your workouts. The workout was amazing as always, it's really as hard as you decide to push yourself. So you could have an easy workout by doing body weight exercises or you could lift heavy. Easy parking in the lot up front.

The gym is very well laid out and has all the equipment you could need. Tons of machines, a large free weight area with benches, a few heavy duty squat racks, cardio machines and a nice turf area. They also offer fitnesses classes, and apparently even have a sauna and a cold tub, but I didn't get a chance to use it. The gym is very clean, including the change rooms. The change room has a shower and lockers with built in locks. The front desk staff were super lovely. I'd recommend checking this place out as a visiter or for a regular membership!

I injured my back in the Army over 10 years ago and it has been a huge strain on my health and weight. Since I've been working with Mackenzie, she has helped with my eating habits, mobility and strength training. I'm fitting in all my clothes better, I'll have to buy new pants soon, my back hasn't given me any problems while working out. In fact my back and whole body feels better than it has in a long time. I'm losing weight and gaining muscle and most importantly I have a way better understanding in what I eat. It's awesome. I can't recommend Train with Dave enough, and I'm excited to continue training here.

I dropped in to do the reformer pilates class through ClassPass with Kady and it was a really good…read moreworkout. Kady had a nice warmup routine that really warmed my body up since I had not done pilates in awhile. During the class, Kady did a mixture of exercises I was familiar with and then some exercises that were different that I quite liked. She did exercises right up until the end and then ended off with a quick cool down session. She did not rush us out which was really nice. We had time to wipe down all of our items and the reformer before leaving. I really enjoyed Kady's class and she offered a lot of help to everyone in the class. She would come over to do some hands-on help and she was proactive in offering different progressions. She was very friendly and encouraging. I definitely broke some sweat during the class. The studio is a beautiful space and definitely a lot bigger than the boutique spots. The atmosphere of the studio had dim lighting and just the right volume of chill relaxing music. I would recommend CirKel Tustin if you're looking for a reformer pilates studio.

The whole space has such a calm, boho, peaceful vibe... dim lighting, chill light volume music, sometimes relaxing candle scents in the front, and beautiful chandeliers. The Tustin location is very spacious, two rows of reformers and tons of room to really stretch and breathe. The reformers are Rialto reformers, where you lift the top to adjust the springs and rings. They're a little older, but it can add to the charm. Every instructor brings great variety to class, which keeps classes interesting and refreshing with something new to look forward to. Sometimes we use sticks for balance, balls for abs, loops for core and leg work, and sometimes dumbbells too, so it really feels like a full-body workout every time. They do count slowly during movements for that deep burn. The instructors are also attentive about form and always ask beforehand if anyone has injuries, which is helpful for me and my knee for modifications. Little cubbies under the benches for shoes and phones. Plenty of parking overall, just be mindful of the green 30-minute parking spots; there's more parking behind the buildings.

I saw a huge transformation in just 3 months and finally achieved a body and fitness goal I've always wanted but could never seem to achieve anywhere else. What I love most is that every workout is challenging but still fun. Jonny is calm, encouraging, and really knows how to push you without making you feel completely burnt out. I also never leave feeling overly sore or miserable, just stronger and accomplished! If you're looking for a trainer who truly gets results while making fitness enjoyable, I couldn't recommend Jonny more!

UPDATE (AUGUST 2026)…read more I'm updating my original review because unfortunately my experience changed significantly over the two years I trained with Jonathan Brown (Body by Jonny). Based on my experience, I can no longer recommend Jonathan due to what I consider unethical and poor business practices. During what I didn't realize would be my final training session, I showed up mentally and physically exhausted. I pushed myself as far as I could but didn't have the energy to finish the full hour. I told Jonathan I wasn't feeling it, wished him a good weekend, and left about 15 minutes early. A short time later, I received a text from Jonathan stating that I was no longer welcome as a client, without any prior discussion or explanation. At the time, I had prepaid for 36 private training sessions and had 15 unused sessions remaining. Despite Jonathan being the one who terminated our training arrangement, I received only a partial refund--approximately 41% of what I had paid for the remaining sessions. When I questioned the amount, he essentially told me that I had already been given a good deal and that "the least" I could do was not give him attitude. I never negotiated his pricing or asked for a discount. I simply paid the rates he quoted me. Whatever price a business chooses to charge does not change the fact that I prepaid for services I ultimately did not receive. I was also never provided with or signed a contract stating that unused prepaid sessions would be forfeited or refunded at a reduced amount if he chose to terminate the training relationship. What I learned from this experience is that a good price isn't a bargain if it comes at the expense of the service, professionalism, and business practices you're paying for. Based on my experience including the abrupt termination and failure to fully refund my unused prepaid sessions I cannot recommend Jonathan Brown or Body by Jonny.
