Today I was looking for information on how many calories I have burned today.  For a person weighing almost 160 lbs, the number of calories burned for an hour would equal to about 170 calories per hour. The truth is, for me at my weight, I burned many more calories for even the lightest yard work at about 319 calories for about an hours work.  However, I only worked for 20 minutes on average today.  The yard work I did was quite light.  That was why I calculated only about 106 calories per 20 minute average.  That is a pretty good measurement all things considered.
