I have been smoking hard for nearly 6 years (smoking dope, cigarettes, and multiple hard drugs), and have gotten extremely out of shape since then, due to lack of exercise and smoking. My body is still decently strong and whatnot, its just my cardio that is lacking big-time compared to what I use to be as a kid. I am currently 19, 5"11 and weigh 160, and I recently tried to jog 0.5 miles and could not finish it, and once I stopped I was very lightheaded, dizzy, and exhausted for the rest of the day. So here is my question
To get back in cardio shape (yes I've quit smoking for a month now), should I try running at a fast pace for a short ammount of time, or go for a slow run (jog) for a longer period of time?
