How We Work

Most fitness professionals promise “6 pack abs in 6 weeks,” or a similar message. We don’t do before and afters because there is no “after.” There is only continuous improvement. Also, our group training creates a community. When you join JKC, you are joining something bigger than yourself.

Custom Workouts in a Group Environment

Get the best of both worlds: a custom plan tailored to your needs and current ability along with the support from the JKC fitness community.

We Offer Flexible Scheduling

No locked-in days or times here. Train when’s convenient for you so you don’t have to miss workouts.

Pay As You Go

Enjoy a different fitness experience. Pay for training on your terms with no long-term membership fees. Out of town? No worries. Only pay when you workout.

Client Reviews

Read what clients have to say about their experience at JKC.

A few years ago, I pinched a nerve in my neck which led me to be stationary as any form of movement would cause extreme pain. During this time, my fiancé (Sean) started at JKC and loved it!! Once I overcame the nerve issue, Sean spent a long time trying to convince me that JKC is exactly what I needed to safely start working out again (I’m slightly stubborn and was super scared of re-pinching the nerve). Long story short, Sean was right… as much as I hate to admit it!

I never had luck at gyms, if it started to hurt I would call it a day. At JKC that is not an option, as Jon & Thomas will push you to finish the workout, whether you want to or not! Working out in a group setting is also a big benefit of working out at JKC, if you’re not feeling motivated you can simply feed off of someone else’s energetic vibes.

I joined JKC because I wanted to better care for my physical health, but didn’t really know how, or where, to begin.  Seeking help from a trainer seemed like a wise choice, and I had heard great things about the staff at JKC. Anyone who knows me knows that I hate exercising.  So, I’ve only ever tried sticking with a gym routine twice in my life.  Each experience consisted of me wandering around, not knowing what to do, and settling for an elliptical machine or something else that seemed comfortable and non-threatening.  Each session was the same, and I felt like I was wasting my time.

Each session at JKC, however, is specifically crafted for me.  I don’t have to think about what to do, because I’m told what to do.  I don’t have to worry about how to do things properly, because I’m shown (sometimes multiple times!) how to accomplish each task.  I don’t have to be concerned about slipping into a comfortable routine, because Jon and Thomas won’t let that happen.

Personal Strength Training by Jon-Erik Kawamoto

Have to thank both Jon and Thomas for their help with my conditioning this past year. After a major injury in 2020, I tried everything. My foot doctor (Dr. D. Sutton) said there was something missing and recommended Conditioning. I then found JKConditioning and it definitely worked for me. Today September 8, 2024 I completed a Half Marathon in 1 hour and 42 minutes and came First in my age group.
Thank you JKConditioning!!!

I’ve always struggled with both my weight and anxiety throughout my life. As a writer you live a pretty sedentary lifestyle filled with both realistic and unrealistic deadlines, so I needed something to get me off my butt and to get me moving. JK has been a godsend during this past year and a half in particular. The pandemic has been tough, but workouts with both Thomas and Jon have really helped reduce the stress and strain of a global pandemic, and added an anchor of normalcy back into my life — which has been worth its weight in gold.

JKC has created an incredibly inclusive environment that’s filled with all kinds of supportive folks from all kinds of different backgrounds. For folks like myself, being surrounded by people with such athletic ability can be intimidating in most gyms. It can actually be a deterrent, and it sometimes has been for me. But, at JKC it’s far from that — it’s inspirational. Everyone supports one another. Which is something that’s not easily found in this day and age, inside of a gym or out. Not to sound like a total cheeseball here, but it really feels like a family.

JKC was recommended by a previous trainer who followed Jon online. He thought Jon’s approach to training was excellent. JKC employs well educated trainers who are very particular about technique and form. I have never injured myself because the trainers know what they are doing. They can always answer any questions I ask about my training. As well the trainers are friendly contributing to a relaxed and friendly atmosphere at the gym.
