GUYS!!!
Today was a really good day healthwise. I drank tons of water, I ate super clean, and then two of ky friends and I went running and I jogged 4 whole miles. slowly, but still, I burned almost 900 calories according to my app.
The problem now is that my chest and throat are reeeally aching, like the feeling of bronchitis or something. is this normal after a really intense workout? I've never worked out this hard. I warmed up and cooled down, I didn't drink any water during the run but did afterwards. It was also pretty cold (in the 50s) but I dressed warmly. I know it is from my breathing...I have terrible breathing technique. I breathe in through my nose and exhale from my mouth. Is this the correct way? Idk...maybe this rattling, itchy feeling will go away as I warm back up bit right now I'm worried I'm developing asthma or something crazy, lol. Input??
