Hey, I see a lot about nasal breathing and its benefits especially for training. However when I train one nostril is always blocked and my nose runs so canโt breathe through my nose constantly ๐. Iโve tried nasal strips but they donโt work for me when training, nasal breathing feels very labored so I have to revert to mouth breathing. Is there any technique I can use to control my heart rate while racing especially when running?
