I have a little heart rate monitor that tracks calories burned based on time, weight and heart rate. If I go by the calculators that just go by time and type of exercise, it is quite different. I also double check it by using the calculator on my gym's website that uses the same criteria as my monitor and they're within just a few calories of each other.

Hope everyone has a wonderful Sunday. I've got grocery shopping then my husband disappears for a couple of hours to take care of the bills (and read his comics!) so that's when I'll get my workout in. Today is the Fast 4 Miles.
