“15% more air supply while I train in the Gym! Making deadlifts I mentioned that I'm more calm while breathing than I usually am. Amazing Bio-Hack to increase performance, even while sleeping.”
“I really had bad sleep for years and was heavy breathing because of covid.. i was worried if these would help me, but i am really surprised how well it worked for me! I finally got a instant effect for my breathing, fitness and bad sleep, because i finally can breathe through my nose like never before! Would buy again.”
