Client Reviews

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

I was looking for something to augment my 20+ year yoga practice with a focus on strength conditioning. I am friend’s with Jon’s sister in-law and over the years always heard great things about JKC, especially with respect to the top quality trainers they have and programs they run. After talking to Jon about my goals, and hearing his thoughts on a training plan, I knew that this was going to be an awesome experience … and it sure has been. JKC stands out from other gyms because of the attention to detail, the high quality of the staff and the facilities. Also, the amazing people that train there. And no one posing and taking selfies. I’m 41 years old and I started in Dec 2021.

I came to JKC through recommendations from my peers from lululemon. As a current ambassador, I’ve been introduced to legacy ambassadors, like Jon, and I knew a bunch of other people from the store were working out here so I wanted to give it a go. I often dread lower body workouts so I started coming here to do legs. I’ve had such great progress that I now come twice a week— and, I no longer hate leg day!

I’ve never experienced this sort of hybrid between group workouts and personalized service. Many group strength training services offer a sort of one-size-fits-all workout for the general population, which has never been of interest to me, because I want my workout tailored to my needs! I LOVE that you can be in a group setting while doing your own personal program; I love the camaraderie and community at JKC, and, I’ve seen incredible results thus far! Jon is always so attuned to what I need.

I’m 35 and I started at JKC in November of 2019. I was coming off the win of the Royal St. John’s Regatta in 2019, and our crew was chomping at the bit to be stronger and faster for 2020. The reputation of JKC leached into our group and away we went! Unfortunately the regatta was cancelled due to COVID-19, but I just loved JKC so much I stuck around. JKC is different from other gyms because the level of experience the team has is unparalleled. Jon, Thomas and Craig all mesh well together and mentor me in a way that I know they love what they do and are genuinely excited to guide me towards my goals (and beyond). I really enjoy the atmosphere, the sense of community and all the positive vibes that I experience in every session. There’s never a time I don’t want to go because I’m motivated by the team’s coaching style and I get results.

I was referred to JKC by my sister-in-law and had heard good things about it from many people in the running community. I also saw Jon’s picture on the wall at lululemon years ago! I really like the personalized training and the variety the guys provide. I started for strength training for running. I love cardio and do tons of it but wasn’t motivated to do much strength work on my own. Jon mixes up my strength work week to week so I don’t get bored but also lets me work in a hard circuit for the last 20 minutes of most sessions to get my cardio fix 

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.
