claim of burning more than 800 calories in an hour - only very
fit people can support this level of intensity for that length
of time.  I always get worried by people who place blind
reliance on HRM's. Those with high blood pressure or on certain
medications can get an increased heart rate, which leads to an
HRM overestimating calories burned. Poor contact between the
skin and the unit can also cause problems.  But when I see an
HRM (especially a new one) reporting about double what you might
otherwise expect, my suspicion is the units of measure. Check
the settings and manual on your HRM. Some seem to default to
using your weight in kilograms (1 kg = 2.2 lbs), which leads to
a calorie estimate of about double what you are actually
burning.  Spark's calorie counter assumes that calorie burn is
proportional to your weight. This holds true for weight-bearing
activities like running, walk
