Joining Altitude earlier this year has been one of the best decisions I’ve ever made! The facility and the people are incredible and it has truly transformed my health and fitness levels. I had never been a gym person prior to purchasing their summit program and I got paired with an incredible trainer who has given me a customized plan and even coached me to finishing my first ever half marathon...

I’ve been training at Altitude Athletic since October, and it’s been a game-changer. The facility is amazing, never overcrowded and the people are always super supportive and welcoming. Highly recommend!

Amazing equipment, facilities, and staff! I would highly recommend this place to anyone interested in high-altitude training or looking to push themselves toward any aerobic goal. I personally trained here for 8 months in preparation for an Ironman race, working with their outstanding trainer, Yaath. I’m not sure I could have completed it without his expertise, guidance, and support.

I’ve trained at Altitude for a few years and for several different objectives (4000-6000m peaks, trekking, endurance goals, strength goals). The tailored and personal approach allowed me to be in the best physical and mental shape for each objective. The gym truely is a community of like minded people and stepping in motivates you to push yourself. The staff and trainers are phenomenal (Josh and...

As both a physiotherapist and personal trainer, I’m really impressed with this gym. The high-altitude environment offers a unique training benefit that can improve endurance, cardiovascular health, and overall fitness in an efficient manner.

The staff were knowledgeable and able to adjust sessions for different fitness levels, and they keep a close eye on technique and safety, which I truly appr...

I really enjoy going to Altitude and impress by that place, firstly because its one a kind gym where you train in a low-oxygen environment to simulate a training at 10,000 feet where you are indeed at sea level outside.
Secondly by the amazing staff there. Everyone is welcoming, really nice and will help you towards your goal. A special mention to the personal trainers for their extensive knowledg... Read More

I trained here to prepare for Everest BC. Gustavo and the team took great care of me. They curated a training program specific to my situation and accommodated for any last-minute schedule changes or requests. I highly recommend this boutique gym, whether to prepare for a trek or for generally working out. Great alternative to the “big-box” gyms.

Altitude is an incredible space for people who are motivated to improve and gain benefits from training at an higher elevation. Personally, I have really enjoyed attending a gym with premium equipment and like-minded people! Highly recommend.

The best gym!! I’ve been working here for almost a year now, for many reasons. The top one is that I love the team and coaches.

Everyone is super friendly and attentive to everyone’s goals & needs. Whenever you have a question about your exercise, any of the coaches will patiently show you the form & things to look out for. And the high-altitude chamber is a great way to improve yo...

I’ve been a member for almost a year! Amazing team! Everyone from the front desk staff to the trainers to the managers are amazingly friendly, kind and always helpful and supportive. They genuinely get to know who you are and what matters to you. They keep up with your fitness journey, cheering on your accomplishments and picking you back up when you’re down!

If you’re looking for a great pl...

I highly recommend Altitude Athletic to anyone looking to level up their fitness. I first joined a friend and was surprised to see how dramatically different I felt training at altitude. After becoming a regular member it didn’t take long to see improvements in my strength, cardio, and heart rate both in and outside of their facilities. The staff is knowledgeable and provides a supportive an...

Great facility with fantastic staff . The variety classes at Altitude prepped me for my first Marathon as well as an Ultra Marathon that will be taking place later this month.

I have for years tried to find a gym that didn’t treat me like a $, somewhere that would educate me and help me understand my body in relation to my goals. But let’s face it; this is everyone’s hope. Every gym has a “schtick,” and in the end, you probably stopped going because once you got past the aesthetics and the basic programming, you realized you were not gettin...

Legit the best gym there is and worth every penny. I started training here July 2022 and could not run even half a mile. Two months later in October, I ran my 1st 5k in 37 minutes. On May 7th 2023, just 8 short months later, I completed my first half marathon in just over 3 hours. Whether you’re working on speed or endurance(or maybe both) Altitude is the place to train.
Also, the coaches ar... Read More

This is a truly unique and amazing place! I’ve trained at Altitude Athletic multiple times and the gym is beautifully designed, high-tech, and the fact you have an entire large room where the atmosphere can change to reflect different elevations is something I’ve never seen before. The staff were very friendly and helpful and they have some great coaches too!

Summit member for 3 months. Can’t speak more highly of Altitude as a “semi-extreme” athlete. Amazing facility and staff, the benefits of altitude training were remarkable for me. I’ve raced ultras for years, joined Altitude with an aggressive race schedule (3 ultras and a marathon major within 11 weeks) and exceeded all expectations with a couple PBs. With lower overall intensity I’m fas...

I love this place as it’s got top of the range equipment and of course you are getting the gains of altitude as you work out. Everything is spotless clean too. The people are also incredibly nice and helpful. Likely my best gym experience in Toronto to date.
