As someone who follows your programming and did this workout day, I have to tell you how good it felt to watch these elite athletes also failing the EMOM after. Not because I want others to suffer, but because I was not in the struggle bus by myself 😂
It’s called a Breathe Way Better. It is an isocapnic trainer (iso meaning static, capnic refering to carbon dioxide levels). It allows you to breathe at high respiratory rates without lowering CO2 levels. I’m using it for warm-up here as a way to prepare breathing muscles for the row / ohs / hspu metcon. As someone who’s dealt with exercise induced asthma for their entire life, I prefer this to using an inhaler on a daily basis pre-workout.
