Do you know why high-altitude training works?

We have all heard about athletes training at altitude, but do you know why high-altitude training works?  (the below link will tell you why)

As studies show, and as athlete scores confirm, high-altitude training is far better than traditional exercise.

For people looking to maximize both performance and time spent, getting the most value out of their exercise effort, high-altitude is the answer.

We sell high-altitude training for home and corporate use AND we also have our own facility, where we have hands-on experience with over 5,000 successful client sessions!
