I used to go through some really rigorous conditioning routines when I was a young man. Pulling and even carrying logs up hills and back down the other side. Sprinting down the street while carrying my mountain bike, then ride back. Running around with medicine balls & wrist & ankle weights etc etc.
I never sounded like I was having an asthma attack even when I was dragging ass and winded. That's because I don't have asthma!! /wink
