Actually works!
Joining the military soon and I needed to control my breathing and strengthening my breathing while running. I use this walking around at work or home. 10 minutes here, 3 minutes there. Off and on while watching a movie. No real set time. I turn it completely shut so I can't breathe out at all. Then turn it just enough to get air flow. Sometimes I plug my nose just to make sure I'm breathing in and out correctly. It'll suck for a while, but 3 days or so in you'll notice a difference. ONLY draw back is the slobber that can collect on the mouth piece lol Read more
