Back in 2016 I wrote a very opinionated piece about Why I DON’T like Optical HR Monitors. Four years ago is a lifetime in the sports tech world. This is an updated feature about them.
When it comes to recording reliable Heart Rate (HR) data, the best way to do so is with a strap around the chest. That is after all where the heart is in the body. But I realise that not everyone particularly females, like wearing a HR strap. The strap gets in the way and can be uncomfortable with a bra, or just annoying being around the chest.
