wow, 29 bpm? Are you sure its contacting properly? I heard Lance has 25 bpm. You can increase your lung capacity by running. I started running before biking, and I almost never get out of breath bikeing (It seems my legs give up before my lungs) I suppose you could increase your lung capacity by trying spinning. Spinning uses less of your leg muscles, instead it causes you to get out of breath. If you can stay out of breath for aroound twenty minutes, you are increasing your lung capacity.
