Jazzing it up

I have decided to change my approach to working out a tidge. I have begun to watch my heart rate as I pedal, instead of the rpms. Yes, I did have to put down the book I was reading and that was a sorrowful experience. In its place, I have begun to listen to audiobooks as I work out and I love that. Back to the heart rate. I get a better work out. I push harder during the easy level times and I burn about 20+ calories more than when I only watched the rpms. I sweat sooner. I tire sooner, but overall it makes me feel better. Feel better about all the cookie dough I can't seem to stop eating this week. I guess I better make it two workout times a day. . .
