Alright so I decided to join the Air Force, but before I go I wanted to get in somewhat shape. So I decided to run the track for 5 min, I stop because my legs were hurting (lack of stretching) at this point of time I was already sweating and breathing kinda rough, no wheezing, no coughing, or chest tightness. I've had asthma as a child before, but I remember the wheezing and chest tightness whenever I was doing something sports related. Is it possible that I still have it or am I just out of shape?
