In this image, a screenshot of my bodybugg program on my computer, you can see the results of today's calories burn. What was interesting for me was to finally see how many calories I actually burn while rideing my bike. As you can see, in the bottom section, the blue lines represent the calories burnt. I rode my bike this morning and late this afternoon. Each time I burned about 440 calories. My work out tonight, was a good burn, a whooping 794 calories! lets hope my scale will reflect this hard work today!
