I think key fitness Hawaii is a very fun way to kick off your functional fitness. It enables you to get your physical exercise with workouts that is not only building muscle for functionality, but also longterm health. When I did it, I had a fun time with a good quality workout.

KY is an amazing trainer. It's not your typical or average training, but it's 100 functional and working for our son. He will keep you on point, focused, and energetic during your training sessions. He also guides you with a nutritional plan to help you in between training days that will help you reach your end goal.

Overall, we highly recommend this gym and his training techniques. He is amazing with our son and very reliable.
5 stars. Only reason being it works. After a for year weight lifting program in my local gym, doing what I already knew: i.e. form vs exertion rate vs burnout. I definitely got stronger during that time, but then I moved to Hawaii from Vegas and need something to keep my fitness up. My uncle and cousin had already been in keys program for about a year. They suggested to joining with them for the first time, I agreed. Little did I know, what would I was getting my self into. My 4 years of weight training flaws were exposed during the first “warmup” of 15 mins!First of this is high intensity interval training. Pretty much an exercise that pays more attention to the functional strength of your natural body movement. #functionalisfit then times the exercise to 6-7 different stations, 1min each full out paced sprints. Full power and drive to push you past your bodies limits. Key is well versed in his area of fitness expertise, where I truly believe he would make us do any exercise he couldn’t do.Second, drive pass your limits.In my 4 weeks with key, I definitely enjoyed the intensity and challenge of the workout. Each week for 1 day a week, left me hungry for the next workout. Key comes up with custom workout routines/courses on his own, put to the test by none other than himself. So, in each workout you join, he can understand the stress and pain and exhaustion you may feel during your 1hour session with him. Many of the exercises were quite new to me in turns of complete isolation form. Which in turn I have incorporated into returning to the local gym.Third. It works.As I said, once a week intense workout like this will have you either hating it and quitting or loving it and persevering. I will attest to feeling pain and exhaustion I’ve never felt before, but the human body is amazing at teaching you what you can or cannot do. I added simple activities such as beach calisthenics and sprints. Every week I returned to train with key, I felt stronger and motivated to do not only better but work smarter. Pace is key to keybatta.I highly recommend giving his workout a try. Being functionally fit is the future of overall fitness. you’ll never know your own capabilities until you try.
Ky is an amazing trainer! He trains my 15 year old son. His workout styles are tailored to each individual and he will help you reach your goals. He is very positive and motivating and knows how to push you! If your looking for a personal trainer Ky is the man for you!!
I’ve know Ky for over 20 years back in our bodybuilding days! Ky has alway been preaching FUNCTIONAL FITNESS way before all those boot camp and cross fit style training. Believe me it works for all types of training from bodybuilding, sports athletes, to everyday health and wellness. I’m grateful Ky can pass his knowledge on to my son & daughter as they train for their high school baseball and softball season! KYBATA! “Functional Fitness” (You Got To Come Check It Out)
The workouts are different from ones I've done before but are really effective. I like the environment and the constant motivation Coach Ky gives. I totally recommend this too all athletes and teens. I'm excited for the new challenges and workouts that are to come.
Been there only a few times, but this is some of the best training I’ve ever done.
I’m 55 years old and came to Ky with lower back issues. In just 6 sessions under his training and guidance, my back hasn’t felt this strong in years! And the back issues are a thing of the past! Best thing is getting to work with these Kybata Warriors every week! I’d recommend Coach Ky to anyone looking to reach their fitness goals!
I had the pleasure of training with Ky during my month in Oahu – and boy did he kick my butt! 💪 As a pilates girl from Canada, I didn’t know what to expect when my cousin brought me to my first session! The workouts were so intense, and so rewarding, I always left the sessions wanting to come back for more!Ky is so encouraging and brings such a fun and positive energy to every class! He pushed me to my limits and it really helped me realize I am much stronger and more resilient than I ever thought I was! I felt so proud of myself whenever I completed a set. I saw so much improvement in my mental energy and physique just from doing a few classes in such a short period of time.If you’re in Oahu looking to try out new workout classes and want an amazing coach, Ky is your guy. His workouts are functional AND fun, I 1000% recommend him to anyone, all ages, all sizes. You’ll come out feeling good as a new person – and with loads of new friends!(Ky, please start an online class so I can workout with you guys! 😅)Much love from Toronto! 🤍🌺🤙🏽
Key works around my military disabilities to help regain my strength and mobility. My girlfriend and I attend as a couple and key is able to modify workouts that challenge both of us. If you are looking to grow your endurance and full body strength I highly recommend introducing some key fitness time into your routine.
I am enjoying the boot camp a lot!!!! The coach is fun and super friendly. He ia so good at helping us achieve our fitness goal. I love participating in this boot camp.
Feeling stronger. Surprisingly my bum knee and lower back are not bothering me as much as I thought it would. Love the variety of things he has us doing and love the fact that I have Yosh to work out with. Wish he had a bigger place.
Key Fitness is a great one on one, focused workout with a personal trainer. Years of experience and creative ways to work you out. You will achieve results if you put in the effort. Very personable and fun to work with!
I usually do not post service reviews, but the Key for Fitness is an exception for Ky's exceptional training. This trainer embodies professionalism, enthusiasm, and care that will push you beyond your physical and mental limits for performance, athleticism, and overall functional fitness. His training and coaching style is UNMATCHED compared to other trainers on the island (that I experienced and heard), and he genuinely cares for every client that arrives at his training. In short, this place is a must-try for all ages, and you will feel like a completely different person after every session and accomplishment from the Key Fitness Hawaii! Thank you as always, Ky!
I had the privilege of training with Ky for a month while visiting my daughter in Hawaii. His workouts were intense a varied. I highly recommend training with Ky!
I have been training with Ky for 3 1/2 months. I have lost 9 lbs and 2 inches of my waist. My friends and family have notices the change in my physique. I train 2x per week. On Wednesday we do a combination of CrossFit and drop sets. This allows me to individually work on my weaknesses. The Saturday sessions feature Kybata. This is Ky’s version of HIIT. The bootcamp at 8 am has a group of 10 people. 10 Stations 4x each. A combination of exercises that work different body parts. 30 seconds in and 20 second recovery. Then a challenge Kybata where teams compete for the Saturday championship.The small group participates at 2:30 pm. This group goes 2 hours. With challenges then Kybata then ultimate challenges to test your recovery and resolve when physically exhausted. Ky tailors workouts from teens to octogenarians. He preaches functional fitness. Living your best life in a body that functions at its peak. Discipline and Consistency and maximizing your potential. I highly recommend Ky’s methods to Functionally Fitness.
I joined Ky boot camp in April. I am writing this review July time goes by quickly. I have enjoyed Ky’s Saturday boot camp. It has helped build more stamina and endurance. I find Ky’s boot camp financial affordable. You can workout at your own pace. Ky is very very welcoming and shows guidance with your exercisesTom M
I'm so glad I found him. He pushes me to do what I know I can do but would stop on my own. I used to just lift weights which I still love but during this functional training is a whole different level of strong and fit. I already am so much stronger and fitter. Can't wait to see what's to come.
I had the best time training with Ky in his group fitness class this past Saturday! I recently moved to Oahu with my husband who is active duty military, and being quite a ways away from friends and family, I have been looking for ways to meet people in my community. Ky reached out to me on the Nextdoor app and invited me to his group training session. I am so grateful to Ky because I was able to meet really great people who are local to me while getting in a great workout!The movements were challenging but the positive environment and all your peers cheering you on made the workout so fun and made you feel so accomplished and good afterward!If you are looking to get into fitness or even if you're like me and fitness has been part of your life for a long time, I can't recommend Ky enough!I am so looking forward to the next group session and can't wait to experience one of his Fitness Adventures!Support your local businesses like Ky and Key Fitness Hawaii!
Right away Ky's personable nature made me feel at ease and motivated. His boundless energy is contagious, which pushes you to give your all in each session. As others have said, what sets Ky's workouts apart is their functional aspect, allowing you to develop strength, agility, and endurance that directly translates to real-life activities.
As a student athlete my goal is to get stronger and increase my vertical. I’ve been seeing Ky for about 3 months and my vertical has gone up since. I enjoy working out with him because he makes it fun and challenging for me.
My daughter and I both workout with Ky. We both have never worked out before. It’a been only 3 months and my daughter is stronger and fit for volleyball. Ky makes working out fun for both of us.
