How we work

Side by side with athletes.

We don't ship a box and disappear. We go to training camps, set up the equipment with the coaching staff, measure each athlete and adjust the protocol session by session. Whether it's a football club in pre-season, a federation or an athlete at home.

01 · We come to where you trainTraining camps, high-performance centres, pre-season hotels or your own living room.
02 · We set up and measureWe install the equipment, show you how to use it and set each athlete's target saturation.
03 · We adjust every weekWe review session data with the coach and adapt the dose to the race calendar.

How we get started

You're never on your own, not even for a day

Behind every session there's a person from our team looking out for you. We set up the equipment with you, design your plan and review your sessions so that every day you breathe the right altitude for you.

  • Personal advisor
  • First month of follow-up free
  • By video call and app
01 · Day 1

Initial video call

A person from our team talks to you face to face: you set up the equipment together, we configure everything and we find, live, the altitude you respond well to.

02 · From the start

Your plan, tailored to you

We set your goals, design your calendar and periodisation, and share the hypoxia protocols that work best for what you're after.

03 · Every week · via WhatsApp

We analyse your sessions

We review the report from each session in the pulse oximeter app and message you on WhatsApp to adjust the altitude. The first month is free, and even daily if you need it.

About us

A team of scientists and engineers.

Altitude Zone was born in Madrid from the union of biotechnology and engineering, with a simple idea: that any athlete can train at altitude without going to the mountains, with the same rigour as a professional team.

We're a sports company. Our equipment is for training and wellness, never for medical use.
