I don't do much running, mostly just weightlifting and a whole lot of walking but after I caught what I believe is the omicron variant relatively recently, I tried to go back to the gym and do a typical hard session. I felt like my heart/lungs were going to burst out of my chest after a heavy set that I normally might just be breathing mildy-heavy after. I've definitely learned to take it a little easy for a while.
