I absolutely love F45 Hawaii Kai. The community is uplifting, positive, and just overall great vibes. As a mom of three, this is the one workout I've been able to stay truly consistent with, because it feels supportive, energizing, and easy to make a priority in my day. What really stands out is how intentional the coaches are. They focus on safe form, they challenge you to grow at your own pace, and they genuinely take the time to get to know each member so they can encourage you in the way you need. All of the coaches are fantastic, but a special shout-out to Pamela, Jess, Duncan, and Ruby their encouragement and attention to detail have made such a difference in my fitness journey. It's more than just a gym, it's a community I feel grateful to be part of. Highly recommend! read more

F45 has transformed my Life!! I have always been focused on fitness throughout my life. Lifting weights, running, swimming, scuba Diving, sports and much more. However, as I get older I find that I require more Functional Fitness in my life. Working in a group format has been amazing! Combining Cardio and Resistance Training is incredible! And the supportive staff is second to none! If you're seeking a Fun ~ Friendly and Supportive environment to assist you in reaching both your fitness Goals as well as your Health, GIVE F45 a shot! read more

I did a 7 days for $7 trial and was hooked!! After working out at home for 10 years I was reluctant, but the convenience this place offers is so great. Many class times to choose from with my varying schedule, and even workouts to use on the app when I can't make it in. This location is special though - something about good jams bumping while watching the sun rise over the water is so motivating during these challenging workouts. On top of that, add super awesome coaches and teammates pushing and cheering you on and you got the whole package. So glad I finally joined! read more

They have NON certified trainers acting as if they are - they don't provide proper ways of doing the exercise and or correct your posture, etc. In addition, have zero training in safety emergencies as well - a few people I know got injured and they did nothing. Hiedi, an acting manager of some sort; micro manages who and when people can work out even though they've signed up within the time frame only to be sent away. I do not recommend this place as it's gone down hill since Jeremy and his wife managed it left. read more

I joined F45 Hawaii Kai in February 2023 and have loved every class since then. Coming off of Covid and home workouts, it was great being back in the gym working out alongside members and coaches who motivated me more than I ever could on my own. The F45 Hawaii Kai coaches are so professional, personable, caring, supportive and helpful in correcting your form especially for resistance training. The equipment is always maintained, clean and the studio is well kept overall. Classes always start on time and coaches are always available for tips and small talk. I enjoy going to F45 Hawaii Kai not only for the rush of endorphins after a tough cardio day but also for the camaraderie, positivity and friendships. Burning off over 500 calories per class is a great plus too! read more

If you're looking for a place to get fit in the Hawaii Kai area- this is it! The coaches are incredible- they will take the time to correct your form to prevent injury and will push you to do more. They will help you with modified movements if you're injured as well. The community of members are very welcoming. The first class is at 4:45am to accommodate our schedules. The last class is at 6:30pm. It's a great place to work out- and did I mention it overlooks the beautiful Koko Marina? The view alone is reason enough! read more

So stoked to be getting back in shape surrounded by inspiring awesome people! read more

Been a member since 4/2025. I never was a morning workout person until I got into F45, now 530a are my absolute favorite time of the day to workout. I make it home just in time to get kids ready for school and don't have to think about workouts for the rest of the day. F45 has been life changing for me and my only regret is not starting sooner! read more

The coaches here are great and they encourage team members to be their best and corrects everyone's form as they go around the room during the workout. Everyone is respectful.

I've been a member of F45 Hawaii Kai since they opened on Halloween 2020, so I've had a solid 9 months of training here, and it has definitely improved my life dramatically. If you told me when I started that I would not only get up at 5:30 AM to get my sweat on, but actually look forward to it, I would have laughed and felt my chin fat jiggle. As the name suggests, the workouts here are 45 minutes long, so really not a lot of time out of your day. You get in, get sweaty, and get done with it. I prefer the morning classes, but they're spread out throughout the day from 5:00 AM through 6:30 PM (except for weekends). They are unlimited, so you can do back-to-back classes, or a morning and evening set, whatever you want. Scheduling is done through an app and it's SO convenient. The workouts consist of plyometrics, weight training, core work, and aerobics, all done in a HIIT format. What's cool is we're all doing these movements together. If you went to a normal gym and you started doing what we do in class, people will look at you funny...like hey why is this guy jumping around so much? My initial concern was that with this style of workout, I might lose weight, but I wouldn't gain any muscle. But don't worry about this. If you eat right and hit those resistance days hard, you will see the fat loss and the muscles grow. There are multiple members that have gone through body transformations during my time here, and it's exciting to watch it unfold. The best thing that ever happened to me was going through their first 45-day challenge. It gave me the tools and the support to dial in my diet and change my body. I am forever grateful for F45 for getting me out of the post-30's "dad bod" that I grew into. read more

When I saw that a F45 was opening up in Hawaii Kai with a waterfront view, I knew I had to try it! I don't think I've ever said "I love working out" before but now I go to class 6 days a week and truly am loving it! Here are a few of the main reasons that F45 works (in my opinion): You can do anything in 45 minutes. You don't have to think about what you're doing, just show up. Just when you're ready for the workout to be over, it is. You see results quickly. Good music. Great people. Large windows with beautiful ocean views & natural light. You feel strong & more confident with every class you take. What more can you ask for!? read more

I can't say enough great things about F45 Hawaii Kai. When I first spoke with David the Manager, he detailed the programs guaranteed results - simply stated, work the program and results are guaranteed to follow. Naturally skeptical, I decided to put this statement to the test and I am so grateful that I did. My wife and I started in October 2020 and we immediately began to see positive results. Fast forward to March 2021 and I can honestly say that I am in the best physical shape of my life at 50. No more 'Dad Bod' and I am very happy to take my shirt off at the beach!!! My wife has had similar results and I am totally proud of my gorgeous wife. From the top down, this place is the best. Coaches who are knowledgeable, supportive and focused on us and a community of members who have a blast working together. If you are serious about putting the work into making positive changes in a supportive environment, this place delivers hands down. read more

WOW! What a workout, what a team, what an incredible location and overall experience. My boyfriend (who never works out) and I tried F45 for the first time a few ago. We were both blown away by how friendly the staff was and how FUN the class was. It all goes by so quickly and I swear my body is already changing. We just signed up for the monthly. It's honestly become something I look forward to daily! Big big THANK YOU to David and his team for getting back in a class and back in shape! PS For those of you that are worried about instructors that may yell at you or make you feel awful, you will not find that here. My boy friend and I both feel incredibly supported and encouraged by the staff and the other attendees. read more

I love that no matter where you are in your fitness journey you feel comfortable with and inspired by all your teammates and coaches to give every workout all you got! Every class I leave with a smile because the workouts are just that fun! read more

Not enough positive things i can say about this gym! First and probably the first thing you will notice is the amazing view. The gym is on the water. They even have an outdoor lanai area to work out and enjoy the epic ocean breeze. Next is the gym itself. I might be a little biased in that i think functional training is the best for the body. You train full body work outs utilizing equipment like kettle bells, row machines, bikes, dumbbells, pull ups, bar bells, and all the body weight excercises you can think of. Another winning part of this gym is the lenght of work outs.. 45 minutes. You literally get your butt kicked for 45 minutes and at the end if youve worked hard enough wont want a other minute. What makes this place on a level of its own are the trainers! Idk where they get their energy from everyday! So much positive encouragement, they make it easy to forget youre out of breath gasping for air. Love this gym, vibe, and members. If youre looking for a place to tone up with a smile this is your spot. Keep up the awesome work F45 Hawaii Kai! read more

F45 is such a great HIIT workout and I love the Hawaii Kai studio! I started out with a free week trail and was sold after the third day! Really transformed my body since I had a baby, the classes are effective and productive. Heidi is very welcoming and great at staying connected. Heidi and all the instructors have great energy, friendly and are super knowledgeable! Instructors are very professional and amazing! They really help correct my posture and challenge me more to the next level. Overall, the studio is pretty nice with loads of natural light and amazing view while you get your sweat one! The studio is clean and organized. Highly recommended to those who are all about fitness and are serious about transforming their body to the next level! read more

F45 Hawaii Kai has changed the way we live our life. I retired from the military 2 years ago and have gained "some" weight since it wasn't mandatory for me to workout anymore. I was feeling sluggish and heavy with no energy throughout my day. My wife tried the free trial and begged me to check them out. I caved in and I couldn't have been more thankful that she pushed me to go. F45 Hawaii Kai became family to us, and our community became larger. I lost 15lbs in a few months ( that's with out a proper diet). My BMI improved tremendously and now I have the energy to keep up with my 4 kids. The pricing is worth it! If you workout 5 times a week, that's $10 a day but you will show up, have your workout laid out for you and for 45 mins you will get challenged, in a good way! read more
