Learning kickboxing as a complete amateur can feel extremely awkward. Didn’t experience any awkwardness at Relentless. The coaches are kind, knowledgeable, and extremely patient regarding questions.
Great environment too, there is a fun energy that takes it from a great workout to an hour you’ll look forward to every day.
If you want to try kickboxing or BJJ but you’re hesitating, do yourself a favour and go for a free trial class.

This place is the bees knees! I came looking for a place to lose weight postpartum and I stayed because of their genuine kindness. It’s a great community to belong too and the owners as well as the other trainers are the bomb dot com! I’m pleased to have found them!!!

Wonderful place, I highly recommend it. Great & fast communication! I went in for a trial class and it was a wonderful experience, everybody that I met was super nice & welcoming. The community there seems to be awesome, I signed up for a full membership the same night of my trial class & I am excited to learn, train & become apart of their community! Great coaching team with lots of experience great for anyone who wants to just get in shape or even get into competition fighting! I have only been to one class but from my experience so far in and out of the gym, it has been amazing!

I have been a member at Relentless for the last 2 years. New and old members here are part of something big. You’ll know what that after you experience your first class in Kickboxing, Brazilian Jiujitsu, Boxing or Strength and Conditioning. Nothing compares to the energy that Pat, Kait and the coaching staff bring to the mats each day. No club can even come close to achieving the same atmosphere and encouragement that you get here. Relentless is family through and through.

The best place to train, period. Their Conditioning program has gotten me into the best shape of my life and their Brazilian Jiu Jitsu coaches are exceptional in terms of attention to detail and support. The owners are dedicated and have gone above and beyond to provide online training during the pandemic, and now it's so good to be back!

I have interacted with Pat and Kait outside of their gym and am inspired by their energy and passion they put not only into their gym, but also their team and more importantly their clients. If you’re thinking about a different approach to fitness, I highly recommend you meet Pat and Kait...

I walked in tonight for a free trial knowing nothing ,and no one. As a beginner I was pretty nervous to be honest. I was greeted by kate the owner which was so welcoming. and with in a short time was very surprised how fast I felt so comfortable. I tried the fitbox womens class. I loved it. It was so encouraging having so many women rooting for me,… when I felt like giving up. That being said I finished a set i normally would have quit! The teacher/s were AMAZING! I can't wait to go back ,and on top of all that I made a friend right away. which was a bonus. I highly recommend this gym. what

The Coaches and the Athletes make the Culture.... it’s a winning combination. It can be pretty intimidating walking into a gym in your mid 40’s (outta shape, trying to quit smoking,etc...) and taking on something like kickboxing. Always wondering if you can keep up, keep pace, endure and not make a complete fool out of yourself as an absolute… NOOB! EVERYONE at Relentless provides feedback, encouragement and helps push you past your preconceived limits. Just when you think your done and ready to give up... someone’s pushing you and helping you find that “one more

I didn't know gym families existed until I came here.
I cannot say enough about the community that is Relentless or of the heart and soul that's put in by all of the coaches every single day.

Great facility, great trainers and great atmosphere! I relocated from Montreal and it took me awhile to find a gym that felt like home, but found this place and have felt more than welcome since day 1!

This isn’t your regular gym. Relentless is a community of people from different walks of life growing stronger together each day. Kait and Pat care tremendously for their team of people as well as their local community of Niagara. Dave is always prepared with fundamental to advanced teachings in Brazilian Jiu Jitsu. He helps us better ourselves every day, on and off the mats. They all continuously show me, personally, what a supportive set of coaches should look like! I highly recommend Relentless MMA & Fitness.

Great coaches and great people help make Relentless a great place for conditioning or training in a particular MMA discipline. Highly recommend to anyone looking to train. You are going to get what you need - from high skill, competition level through to simple "get a sweat on" coaching.
