New Apple Watch unrealistic heart rate on elliptical

My watch is registering an extremely high heart rate during a relatively short workout on an elliptical machine 30 minutes 156 bpm is not realistic

this is a brand new watch (it’s new because I traded in my old model) thoughts

Many elliptical machines can measure heart rate. Have you tried that and compared it to what your watch reports?

You could even use it as a real-time diagnostic tool to evaluate how wristband fit, sensor placement, and/or various arm movements affect relative precision between the two. They might not not match exactly, but you would want to see fairly close agreement plus correlation in trends.


Edit: You could/should calculate your heart rate manually too. No need for NIST - you come equipped with your own gold standard! 🙃 In all seriousness, tho, doing that would let you know if the elliptical sensor is reliably accurate.
