As someone who has recently picked up running, I decided to give this a try and let me tell you it has greatly improved my agility and helped my breathing as I go through this running journey of mine. The first time I used ImpactRx before a run, I was amazed at how open my nasal passages felt. I didn't have to mouth breathe at all during my 2 mile run, which is unheard of for me. My nose stayed clear and I felt like I could take in more oxygen with each breathe. It has been a total game changer for my running. I can actually enjoy my runs now without constantly fighting to breathe. I don't know how I managed without it before. This is a must-have product for any performance-focused athlete. Give it a try and see the difference it makes!
