Client Reviews

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

I am 62 years young and I started training with Jon in 2013. I originally came to join JKC as a recommendation from other family members that were onboard with Jon. Their enthusiasm for the gym experience was quite evident.  I was not to be outdone, so I decided to join as well. JKC, in my mind, certainly stands out from the crowd. I feel it’s a combination of the skill and passion the coaches have for their job and their clients. Each client is treated with the upmost respect and given time to explore their fitness journey without any pressure. JKC is certainly not a cookie cutter gym.The coaches customize your fitness program to suit your needs and your fitness level. This certainly makes sense because no two clients are alike.  This is where JKC excels! Jon, Thomas, and Craig keep the atmosphere at the gym light, but productive. A great combination that obviously works and makes the clients want to come back. Lastly, the camaraderie at the gym is everything. Meeting likeminded people who make you feel you are not alone in your fitness journey is everything.

I recently turned 40, and I have been training at JKC since the summer of 2020. My partner Michael had already been training at JKC, so it came highly recommended. We had set up a home gym at the start of the pandemic, but needed to mix it up after the first lockdown. JKC differs from other gyms because of the personalized workouts. Jon, Thomas and Craig are great at challenging me to do more than I would on my own.

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.

I’m 30 — started at JKC Aug 2016. I moved to NL to open lululemon and we chose Jon as one of our store’s ambassadors, did one workout and have raved about it ever since! The JKC team can adapt a workout no matter what the situation — injuries, new goals, you name it! The trust and expertise can’t be matched!

I chose JKC because I row/coach teams in the St. John’s Regatta and was looking to add strength training to our program. My wife is also running friends with Julia, so I got to meet Jon a few times and heard lots of good things. I like JKC over other gyms because of the level coaching I receive and the gym atmosphere. The energy in the gym helps me through the tough workouts.
