Heart rate monitors and chest straps.
Heart rate monitors help track heart rate during exercise, which helps you train in the right zone for fat burning, endurance or performance and avoid overtraining. Chest strap monitors are very accurate and connect to fitness apps, smartwatches and gym equipment through Bluetooth and ANT+. Armband monitors are comfortable alternatives to chest straps. Check the connectivity, compatibility with your apps and devices, battery life and water resistance before ordering. Heart rate monitors are popular with runners, cyclists and fitness enthusiasts. Note that consumer monitors are for fitness use, not medical diagnosis.
