Is it for you?

Do you ever dream about becoming the best you can be in your sport? The feeling of pushing your limits, seeing progress, and knowing you’ve done everything possible to reach your full potential. Whether you’re chasing a new PB, preparing for a challenging adventure, or simply striving to improve your endurance and recovery, every detail matters.

One of the most powerful tools for performance gains is altitude training, also known as hypoxic training. But not everyone has the time or resources to travel to high mountains for weeks of acclimatization. That’s where simulated altitude training comes in - allowing you to experience the benefits of high-altitude adaptation from your home. It has been an essential part of the training of elite athletes for decades and now it's also available to you. By training or sleeping in a low-oxygen environment, you can boost endurance, enhance recovery, and take both your performance and your health to the next level. Are you ready for it?

Why traditional training isn't enough

In today’s world of sports and endurance challenges, simply putting in the kilometers and hours at the gym is no longer enough. The competition is fiercer than ever, with more athletes pushing their limits, cutting-edge training methods emerging and sports science evolving at a rapid pace. If you’re relying on traditional training alone, you may already be falling behind.

About altitude training

Used by professional athletes worldwide, simulated altitude systems reduce oxygen levels in your environment, forcing your body to adapt as if you were training in the mountains. This can trigger key physiological benefits, resulting in:

  • Increased VO₂ max and power output
  • Improved aerobic endurance
  • Reduced recovery time
  • Weight loss
  • Faster evolution in your training

All about altitude

SCIENCE

What is altitude training?

Altitude training is a method used by athletes, fitness enthusiasts, and individuals looking to improve endurance and overall performance. It involves training in a low-oxygen (hypoxic) environment, similar to conditions found at high altitudes. This can be achieved naturally by training at elevation or artificially using altitude simulation equipment like the ones we offer at KILIMA. By exposing the body to reduced oxygen levels, altitude training stimulates physiological adaptations such as increased red blood cell production, improved oxygen delivery to muscles, and enhanced aerobic capacity. These benefits can lead to improved endurance, faster recovery, and better overall performance - whether you're a professional or hobby athlete, a weekend warrior, or preparing for high-altitude mountaineering adventures.
