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.

I’m 29 and I just had my 3rd Liftiversary 🥳 at JKC. I chose to train here because of the great word on the street and the fact that at lululemon, we’re encouraged to support our local community. My day-to-day routine is very busy, and I love showing up and having to think very little about my workout. The vibes are always good, my music choice is usually accommodated, and the bys are incredibly supportive and compassionate, helping me reach my goals (even when I had a broken hand). I also get to be my weird self, and am embraced fully.

I had signed up for other gyms in the past and never went or rarely went. Something always got in the way or I was just too tired and lacked motivation to go. This way I’ve made a commitment to Jon or Thomas and I try very hard to keep my sessions once I’ve booked in. JKC is different from other gyms that I’ve tried in the past because no one is there to be “seen”. We are all there to get a good workout in and go on with our lives. And it’s a small gym so you get to know everyone and it’s like a big family. When I joined JKC, I couldn’t do a chin up with an elastic band, but I’ve slowly worked up to 10 free hanging chin ups. That was big because I hate chin ups.

I had tried JKC based on the recommendation of a parent of one of my students. I originally started by attending Saturday drop in classes. I was hooked. I decided to join full time when I I had taken a year off from teaching and it was the best thing I have done for myself.

First and foremost the trainers at JKC are extremely knowledgeable. I feel like they are as dedicated to my success as I am. The workouts are tailored to me, my skills and my goals. This is important. Jon and Thomas truly want the best for their clients no matter what level of fitness they are starting from. I also like being able to book a session at a time that suits my schedule. This also helps keep me accountable. Once the session is booked I am not likely to cancel!

I have never previously seen the passion and level of care that Jon and Thomas bring to everyone who works out at JKC. Their knowledge, insight and skills are extraordinary, and they work with everyone individually to ensure the best possible results. The attention to detail and to every person’s specific requirements and goals, and the incredible, constant encouragement they provide, is, in my opinion, what truly distinguishes JKC from any other program in which I’ve participated. I am extremely pleased with the progress I’ve achieved thus far, and it’s largely attributable to Jon and Thomas and the approach they take to training and working with people.

Personal Strength Training by Thomas King

I wanted to add strength training to my cardio, but have always felt gyms to be a bit intimidating, and was worried I would hurt myself without some supervision and help. JKC was highly recommended by several work colleagues. Thomas and Jon are both fantastic, making sure that everyone gets a highly personalized work out in a very supportive environment. The attention to detail and professionalism are second to none. The groups are very small, but very supportive and make the workouts even more fun. Since getting pregnant (36 weeks as I write this) I’m so happy that they continue to help me get stronger while always being safe.
