If you're bent over in a cycling position, the sensor is slightly lower relative to your heart; and if you're stretched out swimming it's almost even with your heart.
Nice Job Alison! in short it’s how hard your heart has to work to pump blood through your body. The reason you HR goes down at the more intense exertions over time and effective training is due to stroke volume increase which correlates to your lowered resting HR. But again you MHR is what it is cuase its who you are.
Whats the best way to see improvements? Get a stress test or graph your intensities intuitively over time and correlate them with the numbers you are seeing . AND RIDE RIDE RIDE
