Super cool private fitness studio! Got a boxing lesson with my sister from Ken and had an absolute blast. I was surprised at how much he was able to teach two first timers in one hour. We burned a ton of calories having a great time, can’t beat it!

I had never done any mitt-work before my session with Coach Ken but he had me feeling myself by the end lol. He breaks things down into easily understandable pieces and is motivating and encouraging while also pushing. And what an arm workout! It was a deceptively slow burn - 2 days after I could barely lift my shoulders! Don’t recommend good a fun workout.

I had the chance to take a boxing mitt session with Ken at Good Health Studio, and it was such a great experience! Ken is incredibly down to earth and made me feel comfortable and confident from the start. He explained every movement clearly and kept the energy fun. You can tell he genuinely cares about helping you improve. The gym itself is also very clean and well-maintained, which made the whole experience even better. Highly recommend checking out a session here

I recently had an incredible boxing mittwork session with Ken, and wow, what an experience! It was my first time, so I was a little nervous, but Ken was super patient and made me feel comfortable right away. He guided me through every move and made the whole session fun and empowering.

By the end, I felt like such a badass! 💪 It was not only an amazing workout but also such a great way to release stress, especially as a single mom juggling work and my business. I left feeling stronger, lighter, and already planning my next session.

If you’ve been thinking about trying it out, I highly recommend Ken!

Hi this is my 5 star review for Ken the Boxing Coach. I’ve watched Ken from 2017 to now 2025 how far he’s came from his health & fitness weight loss journey, and public documentation on public vlogs.

To him exploring Muay Thai, BJJ, and really finding love and a home in Boxing. He’s went from being a student into a solid coach.

Ken is the real deal he really looks into learning the Martial Arts, and Boxing applying all he’s learned over the years passing on his 1st hand experience and knowledge through trial and error.

Ken has sought out to train and learn from some of the best coaches in the game, and California. It doesn’t matter if you are a brand new beginner or amateur athlete even professional, Ken is qualified to help you every step of the way.

Great Job Ken I don’t give out props and sugar coat things in Martial Arts or Boxing but I’m proud of you how much you stuck with it and how far you’ve came this is only the beginning sky’s the limit.

Love & Respect sincerely Coach Vinny Fam 🥊

Just had a great workout with Ken and it was amazing! I’ve worked with Ken in the past as a fitness trainer and he’s awesome at that. Today as a boxing Coach, he’s still awesome! Ken is such a motivational dude and he doesn’t even have to try, coaching just comes so naturally to him. Again I’ve worked with him to some capacity for years and he still motivates me and I’m still learning from him. He takes what you know and finds ways to challenge you. He breaks things down step by step. Once you finish working out with him he makes you feel like a champ, he makes you feel confident and strong. Ken is very knowledgeable and he takes great pride in what he does. He not only speaks about fitness he practices what he preaches. Which is what I think makes him such a great Coach. He’s been there, he knows the struggle and he knows how to communicate that. To quote him “one punch, one breath at a time”. He’ll set you up to succeed one step at a time.
If you get a chance I highly recommend working with Coach Ken.

I’ve boxed before on my own but never worked with a coach before Ken - and I can honestly say it makes a huge difference.

It was a great first experience training here and I’d definitely go back!

I've known Coach Ken for a few years through a different gym, & he has always been an excellent trainer who properly caters his 1on1 sessions to each client by taking the time to understand their needs & skill levels. I hadn't boxed in a year, but I left the session feeling confident in my skills again thanks to him. Also want to mention how clean & beautiful the entire space is at Good Health Studio.

I had the pleasure of working with Coach Ken on a 50 minute boxing session and let me tell you, he delivered. From the moment you step in , to the moment you leave, the attention to detail is immaculate. I have been away from boxing for a months now and I left feeling like a pro. Coach Ken, works at your pace and notices the small details to elevate your game. The techniques not only elevate the heart rate and burn fat! But also teach you valuable skills you can transfer to real life. In only 50 minutes I burned about 600 calories and enjoyed every second of it. Lastly, the studio is well set up, has amazing lighting, and quality equipment. 5 out 5! Can’t wait to go back!

Was I tired? yes. Was I sick with food poisoning the day before? yes. Did I commit anyway? yes. After traveling and working back to back weeks. I found Ken through a very nice friend who posted his business on her social feed. I haven't had a workout in weeks because of work and I NEEDED to do something and personal training always feels comfortable and focused.

Ken was super accommodating, professional, and has a great story himself. He focuses on personal training and weight loss. Ask him about it when you go.

If you need personal training, active training, boxing, and a nice chill space to do it, Good Health Studio is good for that.

I felt like I worked out during and after, but I slept like a baby and felt amazing after! Just do it.

I just had a boxing training session with Ken and he was terrific. I’ve been part of many boxing gyms in the past and I can say with confidence Ken knows what he is doing. The other thing I really liked was the entire 50 minute session was devoted to boxing (using mitts). Most gyms I used maybe spent 15 minutes max using personal mitts. The rest of the time was spent doing more fitness and other types of training such as shadow boxing. Ken went out of his way to make the training personal which I appreciated a lot. I highly recommend anyone looking to either improve their boxing skills or get a good workout to try Ken.

My overall health and body composition has improved over the years I’ve consistently trained with him.
Ken has been great for boxing. I have found him to be incredibly patient as I trained the basics with him and with just a couple sessions I have found significant improvement with my hand eye coordination. It has been a great workout for the development of balance and coordination.

I’ve been training with my boxing coach Ken for a little over a year now, and before that, coach Joon trained me for a few years. Their training methods are meticulously tailored to each student after careful assessment of individual needs and potential.

Thanks to both coaches, I am not the same person who used to suffer from constant pains in the back and legs. I came from barely able to carry myself through flights of stairs, to squatting four plates on regular workout sets. Now, punching combinations and fast-paced mitt work with Ken become my favorite moment of the week. I’ve also found incredible relief from the arthritis in my hand knuckles and joints through training with coach Ken.
Trust me on this, try out these coaches. You’ll see for yourself and become another true advocate of GHS’s motto: Exercise is the Best Medicine.

I started training with Coach Ken at the end of2020 during the Pandemic and because of coach Ken, I discovered a new hobby and a new love…boxing. Sometimes people say old dogs can’t learn new tricks so being in my 40s I knew that it would be a challenge to learn something new. Ken trained me in the best way possible, with patience, knowledge, and stressing foundation and fundamentals over everything. His training was so good that now years later people still can’t believe I’ve been training for 4 years and not 15 years, and it’s all thanks to Ken. I visited him at good health studio recently, a private, very clean, and cozy gym in the middle of ktown. Worked out with him for an hour and he pushed me just as hard now as he did 4 years ago. So if you’re thinking about learning a new craft, picking up a new hobby, go see coach Ken at good health, and you’ll come away from the workout with a new skill, happier, healthier, and more alive.

I had the privilege of training with Ken during my time in the U.S. back in 2019, and it was an incredible experience. His coaching is truly world-class — highly technical, professional, and tailored to push you to your highest potential, whether you’re just starting out or training at an elite level. Every session challenged me both physically and mentally, and the knowledge, passion, and attention to detail were second to none. If you’re serious about improving your boxing skills, or overall health Coach K is absolutely your guy. Couldn’t recommend him highly enough!

I have been receiving personal training from Ken for about a year now, and the results have been outstanding. Prior to working with him, I often felt fatigued and physically heavy. Since starting training sessions with Ken, my body feels much lighter, and I have noticeably more energy throughout the day. I highly recommend this facility and Ken’s coaching to anyone seeking real improvements in their fitness and well-being.

I started working out with Ken when I was focused on weight training and getting ready for competitions.
Throughout the years he’s helped me tremendously in my weight loss and muscle growth journey.
Ken had suggested that I tried boxing with him as another form of working out. I was a bit hesitant because I was shy, and thought I was weak when it came to throwing punches.
When we started I was definitely a little awkward, but as time progressed I learned how to have fun. Ken made the environment comfortable and he’s an amazing teacher. I’m not the quickest when it comes to learning, but he was extremely patient with me.
Ken has been helping me for quite some time, I can proudly say I can hit hard with precision now.
If you’re looking for an amazing trainer to start your fitness or boxing journey I would definitely recommend Ken. He’s the best!

If you want a trainer who truly cares, I highly recommend Ken! He is constantly learning and finding ways to improve so that he can give the very best to his clients and it shows. Ken takes a technique first approach to his training which not only helps you to prevent injury but helps you to truly understand the sport! When your technique is good, your speed and power will naturally follow is something Ken always expresses. Ken doesn't take a one size fits all approach, he gets to know you and tailors his training around your specific goals. You can see Ken's passion for training shine through with each session and that's something I feel is really important to have in a trainer. I will forever be grateful for all my sessions with Ken and I can't recommend his enough!!!

I've been training with Joon Ko for six months and he has been an outstanding coach. In terms of training, he has deep knowledge in different modes of training (strength, building, all-around) and different techniques. He also listens in terms of any specific needs or goals I have, improving my golf games. He is also knowledgeable in terms of nutrition of any trainer I've worked with and he truly changed my approach to food. I highly recommend GHS!

Joon Ko is the best trainer in LA.

I recently started working out at Good Health Studio in Koreatown, and I’ve been seriously impressed. The vibe is welcoming and motivating—not intimidating at all. The trainers know what they’re doing, and they actually take the time to guide you properly and adjust things based on your level.

The gym itself is super clean and has all the equipment you need. Plus, the location in K-town is convenient, and there’s easy parking, which is a huge plus.

I've had the pleasure of working with Joon for many years now, and I can confidently say he’s one of the best trainers out there. He’s helped me not only improve my overall physical fitness, but also work through chronic shoulder and neck issues that had been bothering me for a long time. Joon is incredibly knowledgeable, motivational, and truly cares about his clients’ progress. He’s a great trainer and an even better coach.

Ken, my boxing coach, is just as impressive. I’ve boxed at various gyms over the years, but training with Ken is on another level. He makes every session fun, challenging, and energizing—I actually look forward to working out with him. Whether you're just getting into boxing or looking to level up, Ken brings professionalism, energy, and serious skills to every session.

Both Joon and Ken are true professionals who are excellent at what they do. I highly recommend them to anyone looking to improve their fitness, learn new skills, and enjoy the journey along the way.

GHS is a perfect fitness space! Just enough room to work out with a very intelligent flow of equipment and use of space. All of the equipment is brand new. Filtered water dispenser. Convenient parking in the lot. Ken, Joon and Esther are all amazing trainers! I train with Ken. He is super knowledgable with a multi faceted approach to fitness. Not only strength training but boxing and stretching for pain management as well. Do yourself a favor, book a session with one of them, you won't regret it...
