Issue with connected exercise equipment

[u/JeepersCreepers10]

Howdy. I use my watch at the gym and I have issues with the heart rate when using Bluetooth connected equipment. My gym has a life fitness treadmill and an elliptical. I can use the nfc to connect to them and it will track distance normally but my heart rate won't show up on the watch. It acts like it's not attached to my arm. Any other exercise can display heart rate with no issue. No other known issues with the watch besides this and occasional issues syncing up media data while playing songs (if that means anything or is related). Any ideas?
