I attempted day 1 today and only got half way through the 3rd jogging section. I'm really disappointed. I have asthma. I am on meds for it and always use my inhaler when I exercise. I took my two puffs before I left. One while walking. Another one during one of my runs. And by the third run I was starting to have an asthma attack. My knees and feet were also hurting terribly. I exercise pretty regularly, usually walking for about two miles. I'm about eighty pounds overweight. I'm just really discouraged at this point. I figured I'd try again in two days and see if I can make it any farther. Any tips?
