WEEK 2 DAY8

Today was my first time using the heart rate monitor. It was pretty cool, it kept beeping everytime i seemed to slack and drop out of my "zone". Ever wonder what that weird belt was that runners wore under there nipples? I guess its an electrode device that sends the wrist monitor the signal for your heart rate. I would recommend it. I got the older model, Polar FS1 edition. it still does the job.
