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.

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 started training at JKC in 2016 because I’ve always had upper back issues that became aggravated through work. I sought out other training and physio, but experienced little to no results. A client of mine happened to be coming to JKC for a similar issue and highly recommended it. I have had great success and haven’t looked back! I always feel like I’m getting programs tailored to my needs and I’m never bored. I’m 30 weeks pregnant now with my second child and have been able to workout through both pregnancies here at JKC. Even on my least mobile days, I felt safe to workout because my programs were specifically modified for my needs.

I recently visited Newfoundland for one month, and was looking for a good place to train while I was there. Jon and the team at JK conditioning really took the time to assess what I already knew, and set achievable goals for the time that I had with them. The gym was such a great place to push yourself. It had everything you needed, but more importantly it had a well organized, very knowledgeable, and really motivating group of trainers to push you at each workout. Not to mention a really nice group of other members who also motivated me to go that little bit further. I would highly recommend the gym to anyone who has a goal and wants to find a place to help them achieve it.

I had been struggling with work-life balance resulting in not exercising or playing hockey as much as I had been doing in the past. In addition to being out of shape, I was starting to experience some back/shoulder issues and realized I needed to make some changes. Around this time, a friend (who was also a client) recommended JKC and that’s when I started!

You really feel part of a community where everyone is welcoming and supportive. You get a program that is designed specifically to achieve your goals, with the ongoing coaching, progress tracking and support required to achieve them. The JKC team are very knowledgeable about fitness and conditioning, and very engaging with everyone to answer questions or discuss anything and everything training related. I also like the flexible scheduling and gym times that work for my schedule (I like early mornings and evenings).
