just curious how you guys keep up with your cardio. i had asthma problems when i was younger and its not so bad now. i can go at my own pace doing cardio and not have any problems. problem now is that i am going out for a police test and have trouble breathing from running the 1.5 mile distance outdoors. when i am done i have trouble with my lungs. i cant take a deep breathe. its like the lungs contract. when i take an inhaler i feel a bit better. would anyone recommend taking a puff before the run to open my lungs up a bit?
