The short answer

Breathing air with alternately low and high oxygen through a mask while resting, meant to imitate altitude training. It is experimental.

A few small studies in older and cardiac patients show modest gains in exercise tolerance. There are no long-term results. Walking uphill increases exercise demand. It is not physiologically equivalent to breathing a controlled low-oxygen mixture.
