Ky is a great personal trainer! I originally started working with him while competing for a pageant and he has a lot of experience with a variety of fitness levels & goals. Ky is extremely qualified and always gently pushed me to work during our 1 on 1 hour long sessions. I never dreaded our workouts because he was always nice to talk to but still encouraged me to put in the work. He’s all about positive reinforcement - I never once felt like he was reprimanding or shaming me even if I felt like I was not consistent during the week. This made our communication very honest and transparent, which helped me a lot with my relationship with my health & goals. He has a very reasonable price point for the amount of attention he puts into your training during your session, but also throughout the week. Ky was almost like my personal cheerleader because he was so positive while training and whenever I expressed doubts about my progress. Whether you’re a beginner or more advanced in your fitness journey, Ky will be there to help you achieve those goals. He puts a lot of thought into your program and takes interest in your personal life too to help you work on your goals when you’re not training. Can’t recommend him enough, he’s not just a great trainer but a great person too!

Ky is an inspirational, motivational and amazing personal trainer. He is helping me in my fitness journey and knows exactly how to adjust my workouts and push me when needed. He is not only skilled in personal functional training but he also brings a holistic perspective to fitness. I cannot recommend Ky enough to anyone that is looking for a “personable” personal trainer - he is awesome!!

Key Fitness Hawaii has been an integral part of my family’s health and fitness journey. Though small in comparison to a “gym”, the personal attention you get far exceeds any service they offer. Not to mention the affordability and flexible schedule. I urge anyone who is looking for a safe, clean, comfortable workout environment to give Ky a call. He is the best, hands down!

What I like about this business is that it always has good communication, always professional and good quality. Why is the communication good? I’ll tell you, the trainer always communicates with you even when he doesn’t have classes with you. For example he could face time you when he isn’t busy and if you have a home gym, or even if you are at a gym he could give you drills or workouts to do. The trainer always checks up on his clients to see how he’s feeling or what he is eating. Why is it professional? Well he knows what he is doing. He has the right equipment, the right amount of spacing, and the right amount of drills/workouts. Now why is it good quality? I feel great and helps a lot with cardio. At the start, I’ve trained for about 4 weeks and saw no progress. But, when I started to go to the classes, he worked on my cardio a lot and I was out of shape at first. But 3 weeks in my endurance got way better and stronger. I started seeing a lot of progress. I recommend giving this shot, it is really helpful.

First of all I love working out with Ky! I have tried a couple other trainers, let me tell you Ky is the one to come to if you want total body conditioning! Every time I work out with him I feel stronger then the last session! I love the fact that he will tell you more the less would be good for you to eat so you can diet...and he doesn’t just have us use the computer for our diet! Don’t be scared give this guy a try he is the REAL deal!

Such a great experience with Key Fitness Hawaii, and his take on functional fitness. I’m in pretty good shape aesthetically and when it comes to lifting, but Ky’s training methods definitely gave me a new perspective on where I need to improve in my conditioning.For those of you interested in learning more about functional fitness, you should reach out to Key Fitness Hawaii - training with Ky is such a blast, he tailors his training to fit “You” and will push you to new heights. He’ll challenge and motivate you to strive for better each time you work with him. You’ll know you're leaving not just with an incredible workout but that much closer to your fitness goals!

I have done group training and also personal training with Ky and I can tell you that my body was in the best shape it’s ever been when I trained with him. He knew my fitness goals and helped me to achieve them by always throwing new challenges at me which kept me motivated. His style of training is so fun and innovative-it helped me to get real strong and real toned fast-without it feeling like a chore. I highly recommend anyone at any fitness level to train with him. You will not regret it!

I've known Ky for 14yrs now. I thought I was in decent shape when I met him, he showed me a lot of proper and correct training techniques and helped me for weeks. I saw amazing results, that was 12yrs ago. Fast forward to now, I did a session with him 3 weeks ago and again he showed me that I'm "strong" but I'm not in shape. He customized my workout program based off what I have available in my garage home gym. He customized training videos for me and what to do, he watched my technique by facetime and showed me what I needed to fix and improve. I've seen physical changes and results in the last 3 weeks and I feel much stronger. I'll continue to use Key Fitness Hawaii for as long as I can , he cares about me personally and my fitness. He regularly checks how I'm doing and wants me to send him progress videos. He's a great coach and friend. Highly recommend.

I have never experienced such a marked improvement with my strength and conditioning than when I trained with Ky.He is always encouraging, never intimidating and his style of training motivates you to constantly challenge yourself. A lot of times outside of your comfort zone but it's due to those workouts that you notice results.Whether in a group environment or training one-on-one, Ky's workouts are always fun and tailored to your needs.Call Ky if you're looking for a trainer that will give you results!

I started going to Ky to train for Army Basic Training. As a female, my main concerns were the endless amounts of push ups and running expected at boot camp. With Ky's tailor-made training plans in just two months I went from a 9min/mile to 7:30min/mile. I went from doing 25 push ups in 2 mins to 66 push ups. Ky's charisma and cardio-centric workouts gets results fast. Because of him, boot camp was a breeze and I received the "Soldier of the Cycle" award. Thank you Ky!

I was competing in a pageant and wanted to tone my body up. I found Ky through my family friend and started doing group & individual work outs with him. When i competed in my pageant I felt so confident walking on the stage. He was motivating without the yelling and his exercises were customized for my body type. If you’re looking for something different and customized for you, Ky is the guy.

I am a senior and Ky works extremely well w/me - he is a good motivator, makes sure my form is correct for each type of exercise, and is right at my side if I have a problem w/balance - I feel comfortable working with Ky and feel my strength, endurance and balance are all improving with the workouts he plans for me - he keeps the workouts varied and interesting - it is never boring, just hard work. I give him 5 stars.....

I found Ky through a high school friend’s video. I saw her progress and wanted the same for myself. I knew I needed motivation and that Ky would be able to provide that.I reached out to Ky and scheduled my first session with him. It was one hour long and I never felt that kind of work out in my life. It felt great! He got me to work every muscle and made that one hour worth it. The next day I felt my muscles tightening. I was a little sore for a couple of days but it was the good kind of pain.Ky has a great setup in his garage; he has a wide range of equipment that will work every part of your body. I’ve had many trainers in the past from different gyms and it just never felt right for me; I felt no motivation.Since my first session, I’ve gone once a week. After a month or so I‘be seen some progress especially because I changed the way I ate and began intermittent fasting. With each session I learned something new that helped improve my work outs at home.Having Ky as a trainer, I’ve noticed I am motivated to hike or go on a walk. I noticed my health getting better; my back isn’t hurting as much anymore and I did all that workout without doing much lifting. We did most of the workout with a 10 lb ball.Overall I am very glad I met Ky this year and am looking forward to seeing my progress at the end of the year.

Key Fitness Hawai’i is exactly what I was looking for in a personal trainer and workout. Functional fitness is the top priority and Ky is always fun and encouraging. He knows what your fitness level is and is always changing the workouts to suit your needs and to mix it up. I have done both one-on-one and group classes, both are very challenging and fun! I highly recommend Key Fitness Hawaii.

I have trained with Ky a couple of years ago and I must say... this gentleman does not disappoint, his professionalism, quality, creativity, the unlimited amount of support, the passion and drive he gives really is 150 percent. The amazing thing about Ky is that he really creatively caters to you! Each workout is specifically designed to target certain groups of muscles that trigger key areas and wakes them up. You start noticing muscles you never knew you had or were there. Not every workout is the same either, each one is different, Ky really knows how to make each set different and fun! He not only motivates but he is really innovative too, he is really smart on his workouts, you can tell that he genuinely really cares and takes a lot of time in observing and training you, he really caters to YOU! who is his client, he carefully plans each core section and each on is unique. There is never the same workout sets that you did previously so each one is different. You will get a different way every time and that’s what makes it special! He really is inspiring to train with period. Very smart at what he does! I would highly recommend Ky to everyone!!!

I having been training with KY for the last 5 years. Due to a shoulder injury from previous sports activity from when I was a teenager I had a torn rotator cuff. I'd been to everyone physical therapists, doctors, other personal trainers, but none of them could help me. My shoulder had gotten to the point where I was going to need surgery for it.But then I met Ky who not only was very knowledgeable in the body, but understood how to push me in the right direction. By consistently working out with him, and doing his very creative training routines ( watch some of his videos) I didn't need shoulder surgery.I would recommended Ky to anyone who is ready and willing to start working out! As not only Ky a very positive and encouraging person in general, but he is also willing to work together with you on your own personal fitness goals and needs.

Ky has been my trainer and friend for the last 5 years. I have never been injured once training with him in the last 5 years.DISCLAIMER* it's not easy but it is most definitely worth it!I am someone that love physical challenges.I've done quarter marathons, obstacle runs, functional fitness training and body building shows since I started training with Ky. He has had a game plan and different approach to every challenge. Not just for me but also for my friends and family in group fitness classes.Every session with him has been innovative and challenging, no matter how advanced I became in my training. I just tell him my goals and he helps me achieve them. He gave me tips on dieting, and helped me figure out what works best for my specific fitness goals. He trained me up for my first Great Aloha Race, my first spartan race where I finished 6th place overall in my age group, and my first 2 body building competitions. Ky has been instrumental in my success in fitness.With his current home setup he can train you in any style:High intensity using light weights and calisthenicsStrong man tire flipping and sledgehammer500lb of anchor chainsBattle ropesRope climbBosu ballsTrx bandsClassic squat/bench/dead lifting rackMultiple sets of barbells up to 50lbKettle bellsExercise bike and mountain climbers for cardioUp to 40lb slam balls and medicine ballsHe uses all of these to give you the best workout of your life. His prices are reasonable and his schedule is flexible. Not to mention you get a private secluded workout in a safe neighborhood. Bring your friends and see who lasts the longest in a head to head tabata session!Ky is as positive as he is relentless, and he is dedicated to helping you live out your healthiest life possible. If you have a goal and you want someone to help keep you accountable, and motivated, Ky is the trainer for you!

I trained under Key Fitness Hawaii for many years and still am. Key's coaching is different from other coaches I've been to. I like the quality of his training. I have competed and completed 13 Ironman triathlons, (swim 2.4 miles, bike 112 miles, run 26.2 miles) Key has helped me achieved my goals. With 2 Ironman Kona....Key has pushed me to the limit and I qualified for the Ironman World Championship through Key's strenghthening and coaching twice. (I was not a lottery slot) I earned it lol because my strenghthening training with Key was good.Thank you Key for believing in me. As an athlete himself and the first Hawaiian to represent Hawaii in the Ninja Warrior competition I admired his strength and his hard core training. Will continue to train with you.
