Example of  Interval Hypoxic Training (IHT)

Here is a typical 6-week schedule building up to high altitude during IHT.  Perform IHT with a mask that delivers low-oxygen air generated by the Mountain
Air Generator.  Hold the mask by hand, and use a watch or other timer to execute the intervals. For example, to perform 5 minutes on, 5 minutes off, hold
the mask to your face for 5 minutes, and remove the mask for 5 minutes. During the hypoxic interval, remove the mask briefly if your blood oxygen
saturation gets below the target range.

Measure your blood oxygen saturation with a pulse oximeter.

IMPORTANT NOTE:  Everyone will adjust at a different rate to increasing altitude.  You may  advance faster or slower than indicated below.  If you have
dizziness, headache, or excessive fatigue, return to a previous altitude or shorten the hypoxic intervals.
