Episode 181 -Jason is a doctor/obstacle racer who wrote a blog post that began this way: I’m a lung doc and have spent more hours than I can count studying cardiovascular and pulmonary physiology. This makes it nearly impossible for me to ignore all the attention that elevation training masks are getting. We read the rest of hist post and we found it insightful and humorous. We wanted to bring him on so that we could ask questions about what training masks do/don't accomplish. In addition, we asked him about how to train for elevation, and even IF one should attempt to train for elevation.
