The idea of a heart-rate monitor might sound a bit pointless if you’ve already got one built into your running watch, but what many people don’t realise is that, for those more serious about their fitness data, these monitors can offer way more accurate results.
Don’t get me wrong, wrist-based heart rate tracking on smartwatches has improved loads over the years, but if you do anything with quick spikes (such as HIIT, intervals and circuits) or you just want cleaner, more consistent numbers, a dedicated HR monitor always wins.
