Walking/Running Less extreme hypoventilation exercises (other than the misery I experienced jogging in Golden Gate Park) offer many of the benefits of high-altitude training. They are easy and can be practiced anywhere. Walk or run for a minute or so while breathing normally through the nose. Exhale and pinch the nose closed while keeping the same pace. When you sense a palpable air hunger, release the nose and breathe very gently, at about half of what feels normal for about 10 to 15 seconds. Return to regular breathing for 30 seconds. Repeat for about ten cycles.
