What is Simulated Altitude Training?

Simulated altitude is created by decreasing the percentage of oxygen in the air. Normal atmospheric air consists of 20.9% oxygen, 78% nitrogen with the balance made up of a mixture of gases. In simulated altitude air - the concentration of oxygen can be dropped below 20.9% to create a hypoxic environment.  (Go here to learn about how this is different than real altitude)


Simulated high altitude training systems include equipment such as altitude training masks (worn during exercise) or altitude tents for sleeping.

The most advanced form of simulated altitude system is an Altitude Chamber. This is essentially a hypoxic room that can be designed as a training facility containing various cardio machines and strength training equipment - exactly like a gym. 


Altitude training facilities containing specialized hypoxic chambers or altitude training rooms are popping up in several parts of the globe, including London, Chicago and Dubai and especially in Australia, where they have been well established for a couple of years now in Sydney and Melbourne

At Altitude, we will be introducing the first Altitude Chamber in Toronto, and one of the largest in the world at ~1000 square feet. Our altitude room dilutes the concentration of oxygen in the air to simulate altitudes of up to 20,000 feet with oxygen concentrations of 10% - which is the equivalent of being at the base camp of Mount Everest!


Research suggests optimal athletic performance gains are attained from exposure to moderate altitudes of between 8,000 - 10,000 feet or 14 -16% oxygen concentrations. We'll be keeping our room in this elevation range for classes and open gym time.

About Our 6 Week Intro Program

With our 6 week “ Introduction to Altitude” program you’ll experience what it’s like to train at altitude and feel how your body reacts and adapts. Our program allows for a progressive build up in relation to altitude, intensity and duration.


A full physiological assessment before and after you complete the 6 week program will confirm what you’re already feeling and seeing in your performance...that your hard work at altitude is paying off! Once you’ve laid your aerobic base, we can help you start introducing higher intensity training back into your program.


As with any training regimen you can see results even with minimal use, but we recommend 2-3 times per week to gain the maximum cardiovascular, muscular, and performance benefits.

Planning a race at altitude? Whistler? Boulder? We can help you prepare so you can have the best experience possible. Looking to set a personal best?

We can help. Just want to see the finish line? We’ll help you get there.

Simulated Altitude vs. Real Altitude

The simulated altitude environment is created differently than the environment at actual elevation (like on top of a mountain).


For simulated environments, it's about decreasing the oxygen concentration in the air.

At actual high altitude destinations, the difference comes in terms of barometric pressure. Want to learn more about the effects of real altitude on the body? Click below
