Today I finally purchased a heart rate monitor (watch style!) I have been concerned that the Elliptical machines calculation of calories burned is quite a bit different from the reality!  I have heard that they can overshoot by as much as 20%.  Yikes!!!!
  I want my "calories burned" to be as close to the real number as possible!  I am also wondering if it's ok to be eating your exercise calories.  Does anyone have a thought or opinion on this?  "Lose It" allows you to eat those and, I believe Weight Watchers gives you extra activity points if you choose to use them.  Anyone have a personal story about this they wish to share.  Will my weight loss stall eating these?  I guess im still taking in the same amount of net calories.....
