funniest goddamn lines in the WHOLE Bro-science series.
"For 80 bucks a pop elevation training masks will restrict your oxygen so it feels like your training on a mountain. . .which simulates breathing thru a straw, NOT on a mountain.
Also, have ya asked yourself, How can I look like a asshole faster and more decisively than ever? With this mask, you no longer have to waste time irritating people with your personality or your conversations about mud runs. NOW they'll know you're an asshole from a distance"
It's pretty silly. To simulate 8,000 feet altitude, you just need to smoke twenty cigarettes a day.
