Amazing community and training. If you wanna learn proper form and technique, this is the best place. There's 2 segments for each training session. A conditioning/warm-up segment which gets you very fit through intense body exercises. Then the 2nd segment of the session is the Muay Thai techniques such as attacks and defences. There's so much to learn at this gym from the professional fighters, trainers, and other students alike. Muay Thai is not just a combat sport, it's training for your body, mind, and spirit. For those who are not aggressive or into the fighting aspect of Muay Thai, this Muay Thai gym is an excellent place to get fit (for kids too). The workout here is all in proper form (you won't get injured due to poor form). Go for a free trial to see if you have the determination to become fit and strong. Look, feel, and become your best baby. In terms of facilities, this gym is very WARM. This is good because your body stays warm so you can perform well physically. I been to gyms that are too cheap to turn up the heat and students freeze especially after sweating a lot. Very friendly and respectful peope. Egos to be left outside.

Simon Marcus one of the best to ever do it. Great Muay Thai teacher and coach. If you want to learn authentic Muay Thai and get in tip top shape, this is the spot. Clean and organized facility with a solid team behind it. Also came out to their Muay Thai event celebrating 6+ years. Great night of live fights with plenty of action. Look forward to the next one.

This is the best Gym ı’ve ever been to As soon as you join the gym every single person treats you like a family member which is an amazing feeling. At the end of the first day you’ll have a big family which is something hard to find. Also you will be training with one of the best Muay Thai fighter in the world.(Simon Marcus) I’m so happy to be a part of the family and thankful for everyone 🙏☝️

I highly recommend The One Muay Thai, and jiu jitsu classes. I am a female that needed discipline and structure that was missing during the lockdown. I have been training for over 9 months and I've seen big improvements in strength, endurance, and confidence. The trainers make it fun to train, they focus on detailed techniques, making sure each individual member is trained properly. This place has became my second home and I see everyone as family. 🙏💪👍💖

The best gym hands down! Kru Simon Marcus very knowledgeable and cares about his students. He goes out of his way to ensure that all of his students understand the drills & technique. All the coaches challenge you to be the best you can be. I have trained in Thailand and this is the closest training you can get to that right here in Toronto!

If your looking to learn proper Muay Thai technique and skill, this is the place. The coaches are exceptional and the gym’s atmosphere is unmatched. It is the best gym to learn the art of Muay Thai and an excellent place to get in shape.

Basic to advanced Muay Thai. Definitely family vibes when your there, it’s a place u wanna be to learn and also have fun with your training. Shoutout to Kru Simon and everyone else that helps run this place big love to all and to whoever decides to give The One a try.

Best martial arts, spiritual energy in the city, in my biased opinion. Simon Marcus is a true warrior / legendary fighter for Jamaica 🇯🇲 and Canada 🇨🇦

Simon Marcus is undoubtedly the best Muay Thai fighter to ever come out of Canada. He has fought the likes of Alex Perriera and has beaten Israel Adesanya in kickboxing. He has trained with legends such as Buakaw. Who better to learn from than the best? I have done in class training and personal training with him and both were amazing experiences. The fitness and conditioning during the classes are first class. From the skipping, to the different types of sit ups, planks, and push ups you will definitely get into shape. Whether you are training for a fight or just want to be healthy and fit they have got you covered. His guidance during the personal training sessions is next level. He taught me the basics of Muay Thai and how to execute the techniques properly. He is able to see things, alot of the small details like how to breath, where to place your feet, how to move your body, etc. I know they don't seem like anything major but correcting the small things actually make a difference. I guess I am trying to say he pays attention to detail. He also provides excellent advice regarding any aspect of training as he has been there and done that before.

A gym that feels like home and has a sense of family. A great place for all skill levels to come and develop their martial art skills. Many different classes such as boxing and jiu-jitsu now being provided among the original muay thai class. Highly recommended to come check out the gym Ive been here for almost 2 years nothing but love.

The Best. Simon is a living legend. Just being in his presence invigorates you and makes you stronger. He's an inspiration for all of us. If you want to make your life better and more positive for yourself and those around you....this is the place to be!

I have been training with some sick coaches and trainers at THE ONE, the coaches are some of the most humble, fun and chill people to be around. They will help you correct your technique with no judgment. It’s a great place to start your boxing, Muay thai, jujitsu path . Give it a try, you won’t regret it. and plus you get in shape fast! don't believe me, the guy who runs it is Simon Marcus google him

I highly recommend this gym!! Best energy and place to be at while working on your craft. The people are so respectful and sweet, vibe is all peace and love. Thank you for the amazing PT training experience Mostafa!! I’ll be back for more :)

I have recently been wanting to take up a combat sport and was scouring around the GTA for a gym over the course of a month or 2. I’ve tried some boxing gyms, a couple kickboxing spots, etc, but then I found the One(pun intended). The real question is what doesn’t this gym have. It doesn’t matter what your goals are, whether it be health, weight loss, competition etc.your current skill level does not matter, the instructors will help you achieve your goals at your own pace. I’ve noticed significant gains in my ability level and cardiovascular health almost immediately. They offer Muay Thai, boxing, and jujitsu classes so there is a variety of classes you can hop into at anytime you’d like. The moment I joined I immediately felt part of the family, everyone is so quick to help and fix your form and try to help you reach your best potential. If you choose to not take the class plenty of people are there to help you. This is my first review on google and it is for a reason! If you don’t believe me just come check it out yourself.
