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 40 years old & started training at JKC in 2015. The gym I was working out at closed and my husband recommended JKC. JKC meets you where you are in your fitness journey and tailors the work to help achieve your goals. I’ve trained with Jon & Thomas pre pregnancy, while pregnant and now post baby and they have helped me enormously to stay fit through all life phases.

I joke with the guys often that I’ve seen no change in my fitness level since joining the gym, but the reality is I’m in far better shape at 40 than I ever was at 30 thanks to them.

sumo deadlift

I had always wanted to start lifting weights and get stronger, but didn’t know where to start. I was looking not just for a gym, but for training on proper technique to prevent injury and a program designed for my specific goals. I also wanted a fun and supportive atmosphere to keep me coming back. JKC delivered on all of this and more.

Jon and Thomas have a wealth of knowledge that help their clients get the most out of their time in the gym. Programs are continuously modified to keep the workouts challenging. Even through everyone’s program is unique, you always have the coaches and other clients cheering you on and pushing you to achieve new bests.

I’ve been weight training on and off for years but never really had a specific goal or target in mind so routinely stalled out, plateaued or stopped training all together. Before I joined JKC I was definitely in a fitness slump and needed something to motivate me and get me back on track. I did a bit of digging online, looking at various personal training options and gyms around town but JKC seemed like the best option by far. I’ve tried big box gyms and other personal trainers in the past but none of them have had the perfect combination of goal specific fitness programming, welcoming and supportive environment, and the knowledge and passion to back it all up that you’ll find at JKC. Jon and Thomas are great to work with, they know how to motivate you if you’re having an off day and are well versed in all the different ways to make your muscles burn! I also have noticed some major improvements in my deadlifts since I started with JKC and was really happy with the result.
