My family has had the opportunity to work with Ky regularly over the past few months utilizing his FitTruk and we can’t get enough! As a parent of two high performing student athletes, I have seen lots of training techniques and programs but nothing compares to the functional fitness training that Ky provides. It’s the perfect mix of intensity, strength, cardio and best of all… FUN! We have already begun seeing results, and plan on continuing our FitTruk training sessions. Ky is an incredible motivator and provides consistent feedback and encouragement. Not only does he provide personalized training for each kid, but he also provides important guidance in nutrition and hydration practices. If you’re looking for personal training, or team training to take you to the next level of competition, look no further- THIS IS IT.

Ky is the best! I really needed someone that would motivate me and someone I could feel comfortable with.

I’ve had difficulties working out since I became a single mom - Ky lets me bring my kid, she plays, I get to work out. I don’t feel like I’ve taken away quality time with her.

Ky really tailored my fitness for me and he’s so personable!

I turned 59 and decided to call Ky. As a 5'7", 250 pounder, I did not want to go to a gym because it is intimidating. There are a lot of very fit people and I have no clue how to use any of the machines and free weights. I started functional fitness training (exercises that train my muscles to work together and prepare them for daily tasks) with Ky on June 11, 2025 - two, one-hour sessions per week. After eight weeks I have lost eight pounds, and I am stronger, have more stamina, and slimmer in my midsection. I also see muscle definition in my arms, shoulders, back, and chest areas. I feel much better physically and mentally.

Ky is a great personal trainer and his functional fitness sessions are fun. He is encouraging but not demanding. He pays attention to what you are doing and how you are doing the exercise so it is done correctly. He also "models" each exercise for you and explains what areas he is targeting/focusing on when doing the exercise which is extremely helpful.

If you really want a good investment, invest in Ky. Like you, he wants the best for you.

Reached out to Ky to inquire about senior fitness for my Mom. He responded right away, and we started with an assessment. Ky is high energy and very encouraging, yet approachable for all levels. My mom was hesitant at first, since training is completely new to her, but grew more comfortable and confident as the session went on. We think she will do best training with other seniors, by joining a group Ky trains on Fridays. It's great to know there are many options to train one-on-one, with your family, or in a group. If you are curious, reach-out and try a session, it might just change your life.

Ky fitness is really the “Ky” to your fitness goals!

Short story. I first met him the night I injured my shoulder at the gym that sent me to the ER. (Trying to do a handstand.) Fast forward. I pushed myself through injury to randomly again meet him. This was after I literally did the same exercise that injured me. (Crazy timing) His words of wisdom. “Rest.” Me being too stubborn. “I’m not going to rest. What or how should I train?”
Ky. Well… let me help you. Me….“Ok”
Well this has been the “KY” to bettering myself and my development! His boot camps and specific trainings have helped build and develop me physically and mentally with keeping my shoulder intact! No pain! I’m so grateful!
The group boot camps are affordable and the team is amazing! So diverse. Its not intimidating at all! Really a family atmosphere! Highly recommend.

If you are raising a young athlete and looking for the extra edge, then you got to give Coach Ky at Key Fitness a shot. He is all about functional fitness, focusing on strengthening every key muscle in your body so you can get stronger and quicker, improve your endurance and mobility. For some, it’s a little unconventional at times - pulling chains, pushing sleds, using a sledge hammer to pound tires, flipping huge and heavy tires, pushing a heavy ball uphill, etc. And he will come to train you with 110% passion, always engaging, motivating and positive. He is passionate about his craft, practices what he preaches, and very creative to ensure every workout is challenging. Coach Ky’s workouts will also challenge and improve your mental toughness. My son is 14-year old baseball player and in just a little under a month with Coach Ky, his coaches started noticing the differences in his strength and body movement. But if you come to Coach Key, be prepared to work your butt off because his workouts are no joke.

Ky is one of the most passionate people I have ever met in terms of his craft. He truly wants people to get in the best shape of their life and will push you even when he knows you are out of gas, or at least in your mind you think you are out of gas :) His functional fitness program will push you to your limits in a fun environment with good music and a positive vibe. I haven't felt this alive for a very long time and I owe it all in part to myself for committing to this but even more so with someone like Ky being a guiding light. Anyone who is hesitating going to pay him a visit, just DO IT, you won't be sorry you did. I 100% guarantee on your drive home after your first workout you will know you made the right decision. Aloha!

Ky Vuong of Ky Fitness is amazing! I was waiting for the 'right' time and circumstances to get my daughter to train with Ky. I discovered that such a time really doesn't exist! One day I decided to ask if he could get her on the schedule and he quickly made the time.
With Ky Fitness, it IS possible to have a good time and an effective work out, and because of it, my daughter came home ready to commit to the next week, and she wants to keep on going. On a day she was sick, she didn't ask to cancel, she wanted to reschedule, and soon.

But it's not all work and no play with Ky. He infuses a sense of fun into the training process, making each session engaging and enjoyable. Gone are the days of dreading monotonous workouts – with Ky, you'll look forward to pushing yourself in a dynamic, supportive environment.

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 so encouraging and brings such a fun and positive energy to every class!

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.

Either you’re a newbie or been training for a while, check him out, attend his Saturday session and you’ll be so inspired to make some changes for yourself. Thank you, Ky! You’re an awesome coach! 💪🏽🎉💪🏽🎉

Ky’s Saturday morning boot camp is awesome! He’s super motivating and really challenges you to be the best you can be. He encourages rest and hydration, which is so important, while still giving positive feedback that it is important to know your own body and its limits. You will definitely get a full body burn throughout the whole boot camp! And trust me, you’ll be sore everywhere probably the next few days. 😂 But no matter what it may be, you’re training for a race or just trying to stay active for your health, Ky is a great trainer who is willing to help you reach your goals. He’s so friendly, easy to talk to, and will push you to your limit. Thank you, Ky, for a wonderful experience! I will definitely be returning for boot camp in the future! 🤩

I have been working with Ky for about 5 months and I’m not stopping anytime soon. His functional fitness program is incomparable. He goes above and beyond for his clients, making me feel confident and motivated to do my very best in every session. Not only do I do private sessions but he also accommodates for my group sessions with my coworkers. Ky provides a fun, high energy, and hardworking environment that caters to every individual. Not only do I look toned but my confidence in working out and feeling confident in my own body has drastically changed thanks to Ky. You won’t be disappointed if you train with Ky!

I first contacted Ky through his website a couple weeks before my one month vacation in Oahu. He answered promptly and I was impressed by his knowledge and enthusiasm when talking with him. I knew he would be a very good fit for me. He asked me what my goals were and as a senior, I wanted to be functionally fit with a strong core and also have good balance. I have never trained with a trainer before so Ky started me on some conditioning workouts before my trip and checked on me after each workout, modifying them to suit my level.
I have had 5 sessions with Ky in his gym now. I love how he motivates me and makes me confident that I can complete each exercise. Ky is also very careful that I have good form so that I do not get injured. Each exercise is personalized to my needs and strengths and he takes videos of them so I can see how I am doing. The workouts are so much fun because there is so much variety. Ky has so many different types of equipment so the workouts are never boring. I feel stronger and my balance has increased. I’m able to carry bags up and down the stairs without holding on to the railing. My family is amazed with the progress that I have made when they see the workout videos after each session. I am so happy with Ky’s training that I am going to continue training on line with him after my stay in Oahu. If you want to get in shape, I highly recommend you contact Ky. I am so glad I did.

My 12 year old son has been going through Ky‘s training and practices for several months now. Results are there! My son is much stronger and more focused on his main sport with baseball. Throwing stronger and hitting harder and he says “i feel more in shape and much stronger”. Ky has good motivational skills in getting any age group in shape. Time to time i would bring my daughter to join or i would join with them. Ky focuses more on core strengthening but he can modify and focus what you wanna work on. Great motivator!

Coach Ky has now been training our 10 year old son twice a week for a month now. Coach Ky functional fitness program was exactly what we were looking for during our sons football off season. Our sons strength, mindset, posture, and balance has tremendously improved in just one month. This is probably the hardest our son has ever worked out but Coach Ky makes it fun. Coach Ky is very encouraging and patient with him. He explains everything to him so he understands and he also explains how he can tie the movement to football. Our son looks forward to his workouts with Coach Ky every week. We can’t thank Coach Ky enough on how much he is helping our son grow as an athlete.

Ky is one of the best trainers I have ever been around !

My 11 yr old son loves and looks forward to his training days !

Workouts are challenging but Ky inspires and instills confidence and Sometimes that’s all a kid needs to get it done - than that feeling of accomplishment sets in & that’s when you know this is a really good thing absolutely perfect for my son !

His core and roots will be very strong stronger than most his age and even older and all we have to do is keep coming back.

Low impact on his joints so he can grow without injury but at the same time building strength & power from within.

On top of that he got me working out with my son. It really is a special thing to get to workout with your son. He gets to push me now.

I highly recommend Ky to everybody of all ages I’m 45 and my son is 11 and he can blend our workouts together perfect for what we both need.

Thank you Ky !!

I’ve been doing functional fitness with Ky for 30min once a week for a month now. The mental and physical intensity is incredible and motivates my entire week. My weekly workouts change but I’m actually doing full body every session. I’m stronger in all areas as well as my mental fitness. I’m eating 3 or more times a day but the scale has gone down about 6lbs. The workouts are not basic or monotonous. I feel like I’m actually achieving a goal every workout and it’s changed the way I see fitness. I don’t need a gym anymore or anything fancy. I see the world as my gym. I also find that my to do lists are getting done. Ky makes me feel and understand that anything is possible. These workouts are for any fitness level. It’s me against me! I now know what I’m capable of. The best version of myself is being revealed everyday. I’m forever grateful to have crossed paths with Ky. Thank you for everything.

Consistently uninspired by exercise and fitness, Ky motivates and inspires his “boot campers” to not only challenge each other but to challenge themselves.

Going on a hike in Oahu with Key as our guide was one of the highlights of my recent trip to Hawaii. I visit the islands annually and have been on many hikes but this experience was unique. My group was looking to do a more challenging trail so Key recommended Ka’au Crater. This trail was almost 6 miles with more than 1,500 ft elevation, with muddy trails, large boulders, unmaintained tropical brush, streams, waterfalls, and oh so beautiful.

Key was the perfect balance of hiking with a friend yet with enough knowledge to share about local vegetation and urban legends. He is funny, entertaining, super motivating, and makes you feel you are in safe hands should any problems arise. This trail hike was hands down the most challenging hike I’ve done but easily my most enjoyable. It pushed me to my limits but with Keys help, I didn’t question that it was within my reach. The hours honestly flew by in between our jokes, interesting stories, and Instagram perfect photo shoots lol.

I would hands down recommend him to anyone looking to learn more about the area or are looking for a good physical challenge as he is a fitness expertise as well. Give him a try and I promise you won’t be disappointed!

P. S. He’s thoughtful enough to bring us apples and snacks, had booties and wipes ready for us after we were covered in dirt and took us to a local açai spot. Sooo Ono 🙂 These details definitely set him apart.

One of the best hikes in recent memory, ending at a magical waterfall (from out of the movies or children's books). Key led our team of 12 himself, and was a **motivational superstar** providing encouragement with delicious Fuji Apple slices locally made shortbread cookies as the final reward at the top. I would recommend signing up for any of the outdoor activities offered by Key Fitness Hawaii, and try and get Key himself if possible. Mahalo Brother!

If you are looking for adventure and fun Ky is your guy. He took me, my cousin, and my friend on an amazing hike up Ka’au Crater hike. It was about 6 miles, around 1,500ft elevation and 3 gorgeous waterfalls. The hike was challenging and adventurous. He made it so much fun and provided educational insights. Whenever I’m in Hawaii I will definitely have Ky take me on another. I recommend him to all my friends, family and to you all.

My body has been broken for many years. I have connected with many personal training situations. I’ve mainly connected with doctors because the conditions of my shoulders and knees from years of martial arts. Finding Key Fitness has changed my life. His outlook on fitness and personal training is definitely unique.

With his energy level and the way he physically looks, I was intimidated and calling him. I thought he might be too hard core to work with someone who needs to slowly rebuild.

Now that I’ve had the guts to call him and work out with him, I wish I did it many years ago.

I have a large amount of injuries in my body. In some situations I cannot function normally. He has not only given his advice on how to work out but he has also been actively researching better ways to adjust his workouts to my body.

I am now doing a custom training session that I don’t think I could get anywhere else.

The personal attention you get here is outstanding. He literally spends every minute with you pushing you in a manner where you’re not going to hurt yourself but to repair yourself.

I’ve seen him service broken people as well as people who think they’re at their fitness limit and then they meet him and he gives them the next level.

I finally have hope to be strong again like I was when I was young. This is changing my life and I deeply appreciate his personal training expertise.

His functional fitness approach in his personal environment with nobody else bothering you as part of it brings so much pleasure to working with him.

If you need personal training, functional fitness or even dietary advice. He has a unique perspective on nutritional programs.

He tries his hardest and everything he does and his passion and drive is his family and fixing humans. Definitely look him up you will do yourself a favor.

I trained with Ky back in 2016 when I was preparing for the 2017 Miss Chinatown Hawaii/Miss Hawaii Chinese Pageant. His sessions were always rigorous, but he knew how to make them fun and enjoyable. I wanted to lose fat and gain muscle, so he designed personal workouts for me to reach my goals. He even took the time to take videos of me working out so I could watch my improvements over time— which I am happy to say there were a lot of! He also gave me a personalized meal plan which consisted of a high protein diet which allowed me to see faster results. I gained more muscle tone, while still maintaining a slim physique. I felt stronger and stronger after every session, and even on the days where I thought I would pass out (hello Tabata workouts lol), Ky’s positive spirit and energy kept me focused and I was able to crush all of my personal goals. With his experience in body building competitions, he was even able to help me with my walk, posing, and overall stage presence— all of which helped me tremendously in my pageant competition. I ended up winning the title of Miss Hawaii Chinese 2017, and if there was an actual award for the Swimsuit competition I would have dedicated it to him. Thank you so much, Ky!

I have had several sessions with Ky over the past 3 weeks, and am really enjoying my training so far. Ky is both motivational and encouraging, but also challenges me. I fear he is going to catch on to my sandbagging and will ratchet up the pain...but it is what I need! And I can already tell from just a handful of sessions that he is very attentive to a training regimen that is tailored to what I can physically handle, but is always going to push me mentally so that I continue to improve more and more. Since I am trying to lose a lot of weight and get back into shape, Ky has given me homework assignments, checked in on me via text, and even stopped by my house to see what my home gym setup was like so that he would know what I can do at home to further tailor my "homework" workouts. I have never had a personal trainer before, but so far so good! Let's go get these goals!!

It was so sudden. In the morning, I went in for a heart check-up. That afternoon, I was being prepped for surgery. It ended up being a cardiac quadruple bypass. A month of slow recovery, dependant on others to help me do simple things followed. Imagine barely being able to walk up and down stairs without using handrails because you cannot put any pressure on your upper body or risk tearing the newly repaired heart arteries. Getting out of bed was a task. I needed my legs, quads, hamstrings, and glutes to do all the heavy lifting. Most of all, I needed my core muscles to support their work. Guess what?!! I had nearly zero core muscles!

When I was cleared to exercise, two months later, I was nervous. I felt so weak. I felt like it was impossible to be stronger with my weak heart. I didn't want to be judged by a fitness buff. I didn't want lectures. And, I didn't want to be in a gym figuring machines out with people around me.

What followed changed my life.

I met Ky Vuong. I talked to him about building up my core strength. There was no judgement. He was supportive. And, he goes at my pace challenging me when he can and easing up with low impact exercises when I'm winded. I am not in a group setting and I never once felt less than for not being in shape.

It’s been about three months on a once a week workout with Ky. I have noticed my strength returning better than even before! I have improved agility with the core workouts, and the balancing training which I sucked at on day one, is now fun! Every week he introduces a new variation into the workouts which are anything but routine. I can handle the stairs and carry groceries now. My girlfriend even said I've improved my posture!

Ky has terrific interpersonal skills. He's patient with a novice like me even though I know he has high intensity clients, too. If you are like me, a non-fitness guy who just needs to be a little stronger today for a better tomorrow, and you're also wanting a dynamic, interesting, and different workout everytime you exercise, please consider giving Ky Vuong a call. I'm so glad I did.

Progress. Momentum. Results. Lifesaver. These are a few out of many positive words that describe my experience with Health and Fitness Coach, Ky Vuong.

In May 2021, my partner underwent heart surgery. From that point, I listened to the universe's very clear message that he and I needed to give ourselves the care and focus that we've been neglecting. For him, he needed to rebuild those critical core stability muscles to include re-strengthening his newly repaired cardiac muscle. For me, I wasn't as disciplined as I needed to be to maintain a fitness regime on my own. I walk a mile every other day, but that's about the extent of necessary exercise I give myself. My partner and I didn't want to do the gym route. I personally tried distance training on video, going through tabata and yoga routines uninspired. And, I was not in a position to help train my partner who was still recovering from heart surgery. My partner and I realized we wanted a guide who could understand our unique and very different needs and who would be okay with us going at a pace that was a balance of challenge and comfort for each of us. I trained with Ky more than four years ago, and knew he would be the one to help us now.

I called and he wouldn't start with us right away as he required a doctor release my partner for exercise. Three weeks later, we had our first meet and greet session. Ky inspired us and challenged us with the right amount of balance that my partner felt safe to return again and again to work with Ky more. We love the one on one unique functional fitness exercises. We love his anecdotes and fun personality. We love his professionalism and genuine care for the human condition. We even love his new puppy Rocky!

I am so proud of Ky because he loves to give his knowledge to coach EVERYONE! What I mean is that he coaches the whole spectrum from kids, to recovering heart survivors, to ninja warrior type clients, to family fitness groups, and to senior citizens. I am most inspired by one of his senior citizen clients who has been training with him for more than 4 years. He said she loves to travel and traverses the world alone. She doesn't want to depend on anyone to lift luggage for her or struggle with mobility. She committed to keep herself strong in mind, body, and spirit. And, he is humbled that she chose him to help her along the way. I want to be like her - strong in mind, body, and spirit. I think she found the real key to fitness.

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.

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!

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!

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.

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 calisthenics
Strong man tire flipping and sledgehammer
500lb of anchor chains
Battle ropes
Rope climb
Bosu balls
Trx bands
Classic squat/bench/dead lifting rack
Multiple sets of barbells up to 50lb
Kettle bells
Exercise bike and mountain climbers for cardio
Up to 40lb slam balls and medicine balls
He 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. Mahalo & Fa'afetai.
