bought one of those fancy dancy Garmin Insight 2 Solar watches to help me improve my physical fitness...Anyway, I went to the track today and ran, and came home cleaned up and turned on the baseball game in the 5th inning....MY HEART rate is nornmally 56 to 58 at rest.....It stayed ABOVE 90! Until that WALKOFF!!!! Immediately dropped to the 70s!! Not a joke....
