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 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.

So first of all, the welcoming of the staff at this gym is far beyond all the others in the area. You’re welcomed by professionals and directly you feel including in a team that will push you upward. Secondly the gym area and the showers are so cleaned and well maintained. And to finish the gym is newly, amazing and the trainers are focused with you, super friendly, professional and they give great support. Great place !

Really positive and supportive environment. I came in knowing nothing and I’ve had a lot of fun learning and gaining confidence with different techniques. The gym is clean and well maintained. The coaches are really attentive and knowledgeable - they’re always happy to offer tips.

I am absolutely thrilled with my experience at Relentless! The Strength & Conditioning classes have been life-changing. I can't thank the S&C coaches (TJ, Kait and Chelsey) enough for their exceptional support. The atmosphere is welcoming, the workouts are challenging yet rewarding and the sense of community is unparalleled. I highly recommend Relentless to anyone looking to achieve their fitness goals and be part of an inspiring fitness family led by owners Pat & Kait Chapman.

If you are looking for activities for your children 5 and up this is it. Our kid go to the kick boxing classes and they not only learn self defense but also get a great work out and meet other kids. The owners and coaches are all lovely people. We will probably be life long customers here. The facility is clean and well kept as well with clean washrooms. The parking lot can use a little improvement but that is the only con of this place.

Joining relentless was easily one of the best decisions I've made in my adult life. I was overweight , my mental health was suffering and I took a chance at this Gym with 0 experience and I'm so happy I did. I've lost almost 30lbs in 6 months and feel like a whole different person. I was nervous my first class and Coach TJ and Jordan did an amazing job making me feel part of the family from day 1. The owner coach Pat is constatnly challenging and pushing us to become the best possible versions of ourselves and I couldn't be more grateful. If you are on the fence to join or not , i strongly encourage you to take a trial class , the atmosphere is great and I've met some really awesome people. I hope this Gym continues to grow and receive the recognition it deserves.

My boys LOVE their kickboxing class. The coaches are patient but firm with kids, which they need. We love Relentless, would 100% recommend to anyone looking for a gym.

I trained here for 4 months and already felt like a part of the team. The gym is always full of energy and enthusiasm and it's good to train among people with high morale. Coaches are top notch, they help you figure out every single detail you are wrong at and push to excel. They also take good care of you and help develop a learning environment. Personally, All I wanted to do when I joined this gym was improve my stance, punches and footwork but ended up doing much more and loved every bit of it. Doing all Kickboxing, Boxing, Jiu-Jitsu takes a lot from you but I would say it depends on how far you want to go and what your goal is. For me it was trying all of it and make use of my free time. The thing I liked a lot is that coaches work on specific schedule and a game plan so being consistent matters if you want to learn and make most out of it. Lots of love and respect for "Relentless" coaches.. thanx for taking me in the club and help me learn and improve.

An extremely positive and supportive environment full of hardworking and disciplined people, I was around 260-270lbs when I first joined Relentless, I’m now one of their competitive kick boxers and weight 215lbs. They helped me with more than just weight though the coaches and community played a big role into the person I’ve become.

What an amazing experience at this gym. Being there a year now as a family, Pat and the Relentless coaches truly care for the health, well being, and progression of every one of the Relentless family. My wife, my son, and myself all have different skill levels and goals, but they fine a way to challenge all of us.

Amazing group of coaches! I want to thank the coaches at Relentless for going ABOVE and BEYOND in modifying workouts while I have been recovering from a broken arm. This has allowed me to continue on my fitness journey during the healing process and physio with incredible support. I’m extremely happy to have found this gym !

In the past, I always had a hard time sticking with a fitness routine as I was never really a "gym guy". The "Strength and Conditioning" classes here are fantastic. The 45-50 minute workouts are intense and varied and the instructors are very encouraging. The environment is welcoming and free of judgement. I recommend Relentless MMA for anyone regardless of where they are on their fitness journey. I've been going several times a week for almost a year now and have noticed a marked improvement in strength and endurance.

Best gym around! The community environment makes everyone feel comfortable and Pat and Kait are great instructors! Learning a lot with a killer workout - 10/10

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!

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!!!

Awesome staff and great welcoming environment. Clean and well lite facility. Free onsite parking.

New members to Relentless and our experience has been wonderful so far. The coaches are fantastic and the gym is well taken care of. Highly recommend!

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!
