exercise help

First of all you need to consult a doctor before you continue exercising. there might be a problem with your heart or maybe you are too overweight. It would be more beneficial if you have check up first.

Right. Or it could be a lung problem. In any case, a doctor should be consulted. I have mild asthma, which sometimes gets worse when I walk briskly in very hot, humid weather. I always (well, not always. Sometimes I forget) take my Albuteral with me, in case my lungs act up.
