So what are the symptoms of exercise induced asthma? I've been thinking about this lately and plan on talking to my Dr. when I go in for my yearly checkup.

I feel like my lung capacity hasn't increased like I would imagine it should. Or maybe my aerobic capacity. Last summer, I weight 220 and could hardly do 10 miles around the lake. Now I weigh 140 and can do 50 miles are so and I am riding around 100+ miles a week. I still struggle so much on the hills (I am in Dallas, it really isn't all that hilly) Starting on the first hill of my ride, it feels like I can get enough air and sometimes I wheeze. It also takes me awhile to catch my breath again. I don't know if I am just not a hill climber or there may be something else.

Any thoughts?
