Hey I am a new member to this site. While looking up how many calories I burned during spin class I came across your spark page. I wear a HRM and it seems to be on the fritz. I've changed the battery. I only get two dashes across the screen or a very low HR reading (74). Do you have any idea what's the matter with my monitor? Or how many calories I burn? I'm looking for some kind of formula so I can have an accurate number to put in my calories burned. Thanks for the info.
