When it comes to optimizing your workouts, heart rate monitors can be a useful tool to help train your body to work as efficiently as possible. Not only can you track your heart rate, but the latest technology can give advanced analytics on a wide range of data including calories burned, body temperature and recovery rates.
Heart monitors have come a long way since the guy next to you in spin class strapped a belt around his chest and tracked his pulse for the entire class. Today's heart rate monitors, including smart watches like Amazon's top-seller Apple Watch 8, are so much more.
And thanks to Amazon Prime Day deals, you can save big on the best selection of heart rate monitors.

Heart rate monitors vs. smart watches
Sophisticated smart watches like the Samsung Galaxy Watch 5, which also track heart rate, are a terrific way for anyone (fitness enthusiasts or not) to get real-time feedback on their heart rate, and other data like calories burned and body temperature. So why use a heart rate monitor when most smart watches track heart (and you can get text and email alerts?)
Simply put, heart rate montiors give the most accurate heart rate measurements. A heart rate monitor like Garmin Dual HeartRate Monitor sits closer to the heart and isn't subject to being obstructed by movement, sweat or hair like a smart watch which sits on the wrist. The slight discrepancy in data likely won't matter to most fitness enthusiasts. But for swimmers, mountain bikers and cyclists, a heart rate monitor will stay in place easier, giving more accurate data.
We'd also suggest those doing weight and kettle bell workouts use a heart rate monitor over a smart watch to keep the wrists obstruction free from weights and kettlebells that may come in contact with your wrists, bruising them or breaking the watch.
Most newer versions of heart rate monitors connect to newer smart watches. Since a heart rate monitor will give the most accurate feedback, consider using a heart rate monitor connected to your smart watch for endurance training like long runs or extended biking trips.
