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 saw an article in Men’s Journal that quoted Jon in about 2018 while traveling and was impressed that someone in St. John’s made that international magazine.  Jon spoke about an exercise called the Farmer’s Walk and I started working that into my routine at the YMCA. I tore that article out of the magazine and kept it, meaning to make contact, but got busy. Then I had lunch with an old friend Bruce Dyke. I hadn’t seen Bruce for a while and I remarked that he looked super healthy and fit. He told me about his, and his son Cas’, experience at JKC and then I remembered the Men’s Journal article! No coincidences!

The experience is unique on many levels – great people, camaraderie, passion, purpose, and dedication. Jon and Thomas are attentive, precise and understanding.  Their teaching has unlocked a new perspective for me with what our bodies are capable of. I still appreciate the YMCA, wonderful place, but I can’t imagine working out without Jon and Thomas now.

Nutritional Coaching by Julia Howard

From my initial consult with Julia, she was professional and knowledgeable as both a Registered Holistic Nutritionist and athlete. She was interested in my nutrition and fitness goals and the development of a plan that would set me up for success.

Julia designed weekly meal plans that were complete with recipes and shopping lists. The food choices were nutritious, easy to prepare, and ensured that I felt well nourished and energized throughout my training and non-training days. Not only do I feel leaner and more fit, but I have more energy and I feel much more in tune with my body and food choices. Julia really helped me put everything in place so I can continue this process going forward- I cannot thank her enough!

I had spent a fair bit of time in gyms in my teens and twenties but I turned away from the gym to focus on activities that I enjoyed more. What keeps me at JKC is that I do really enjoy it. I always feel that I’ve accomplished something when I leave at the end of my workout. The environment is really positive and focused on challenging yourself whatever your level of comfort and fitness. I’ve also seen results that I’m really happy with; having someone who really knows what they’re talking about to guide your workouts makes them way more effective and focused than just “going to the gym”.

Shortly after I started at JKC, I sustained a fairly major injury that took me off my feet for several months. When I started to get back to activity, it was very difficult. Jon and Thomas worked hard to tailor my workouts to my goals and what I could do. With their help, I’ve been steadily building back strength and function.

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.
