Edit* automatic grounds for termination? maybe it is maybe it's not, in reality you have a choice how to respond to someone who significantly supported your business for a long time. I personally don't think she overstepped her bounds and clients may or may not migrate. Clients will make that choice for themselves with or without cutting her short.

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.

We stumbled upon this place with their 1st class free (you can book through mindbody)! They offer…read morea $99 one month unlimited trial so we signed up for it. The place is spacious compared to other workout studios I've been to in the area. The format is mainly 5 stations with an A & B exercise. You can start at any of the 5 stations & you'll do sets of the A workout followed by the B workout or vice versa. Monday/Wednesday is upper body Tuesday is lower body Thursday is glutes and abs Friday through the weekend is full body (this location isn't open Sunday so you'll have to hit up their other location) We've been going to the evening classes which are taught by Meghan. Who I'd say is one of our favorite instructors (we've been to two other instructor's classes). She's good with explaining and keeping time. She's also a good balance of being a cheerleader/"woo girl" or coming over when you're butchering the exercise! Be prepared to say hello & give your workout buddies high fives!

I've tried everything--from traditional gyms to ClassPass and CrossFit, until my sister introduced me to Ark Fit. The facility has all the equipment you could need, but what truly sets this place apart are the coaches + staff. They have created a warm, welcoming environment and built a supportive community. Open gym is always a vibe and kept so clean. The classes are as challenging as you want them to be, and coaches meet you where you're at. Every coach brings the same positive energy, understanding, and kindness to each class. Regardless of your fitness level, you'll never feel lost or left behind. If you're looking for a gym that combines expert coaching, an incredible community, and a truly welcoming atmosphere, Ark Fit is the place to be.

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.

Unfortunately, she lives in Long Beach and they wouldn't honor the gift certificate unless you live within a 10 mile radius. We were given the options of buying a day pass or sign up. After a bit of bickering back and forth, we decided to leave. The 12 may be a good gym - but it def left a sour taste in our mouths. It was def a bummer that we weren't able to try them out and test the ice plunge thing. Oh well.
