Subject: Heart rate zones I have been reading Ironfit and I am finally going to start training by heart rate zones. I love the book by the way. I also got a Garmin 910xt for my birthday. When I was setting it up on Garmin Connect I set the zone % based on what Ironfit said each zone should be. The problem is that there seems to be a discrepancy between the two. The Garmin is telling me my zones are higher than what the book says. I.e. Zone 2 (based off of max of 185 ) should start at 139 (75% ) but Garmin tells me 151. Is this because the Garmin is also taking into account my resting heart rate? I haven't done an actual test so yes I'm just going off of generalities here. Thanks. |
