Is the heart rate accurate if I wear my sense on my ankle?

[MandiZ]

I just got a treadmill desk for work to get moving more often, but I noticed my Sense wasn’t tracking most of my steps while I was typing or resting my hand on the desk. I read that people fix this by wearing it on their ankle to accurately measure steps. When I tried this going 2mph for 20 minutes, I noticed my heart rate spiked higher than normal when walking, and I was almost to my cardio range. This may be possible, but seems unlikely - does a Fitbit Sense worn snugly on the ankle accurately read your heart rate or is it recommended to either ignore the HR when wearing on ankle or assume higher steps when worn on wrist?

Thanks!

Hi @MandiZ - have a look in the forums about heart rate in general not being accurate during exercise, it seems it's a known issue, so it probably doesn't matter where you wear it.

Give it a try @MandiZ then report back with the results. 

I always took my pulse after a bike ride, all I needed was a watch with a second hand. This was before the digital watch. 

Now all I need is seconds displayed.
