Heart rate

[weezl6273]

This morning I was on a friends' treadmill, the first time in several years, I know I am really out of shape, but, when I started to walk my heart rate was 81 on their machine. As I walked at 1.5 mph my heart rate slowly went up. I increased the speed to 2.5 mph gradually until the heart rate monitor read 118. Then it suddenly started falling. I lowered the mph back to 1.8. My heart rate wnt down to 68, then started to climb back up. I increased the mph up again until my rate was 134 and finished the 15 minutes and quick. This did not seem normal. Was it really my heart rate, or the monitor?

You say you are out of shape but your heart seems incredibly healthy. It is responding to your requirements perfectly. I would say the monitor is fine given the figures you have posted. I bet your friend was jealous, I am.
