Does Powerlung really increase the power of your inhalation muscles by over 40% and your exhalation muscle power by over 150% because I'm thinking about buying one? Do you use one of them yourself?
Answer by Dominique:
Thanks for your question about the Powerlung. I have heard about the Powerlung, but have not used it myself, nor have I seen any hype around it yet.
It could be a great device and maybe genuinely helpful, but I have got a bit of difficulty believing it. It sounds too good to be true. The only way to become a faster runner is to train hard, in my opinion.
