Just how many calories am I burning?

I'm always wondering how many calories I'm burning!  While I'm working out my thoughts are getting a workout of their own....Did I burn off that bagel that I shouldn't have eaten for breakfast? What about that candy bar that I ate yesterday and regret today?  I also wonder what is better: running, biking or hiking?  Luckily, there are lots of calories-burned calculators on the internet! I get inspired just plugging in different activities and seeing just how many calories I can burn doing different activities!  Here is a link to one on the Glamour website.

That's me hiking with my hike leaders last Spring.  That was a tough hike! We burn over 1,000 calories in a 4 hour hike! You have to burn 3,500 calories to lose 1 pound!  Makes sense to me...eat less, exercise more!
