Ava · Yahoo User

I'm very interested in getting some kind of a device that monitors my heart rate and my caloric output, but i'm not sure if the body bugg is for me... for starters do you have to use it in corelation with the online program????Basically i'm choosing between a body bugg and some kind of Heart Rate monitor watch. But i'm really wondering of those watches are even accurate!i need some solid advice! Thanx!
