Which fitness product is best for tracking heart rate?

@percy 

There are several fitness products available for tracking heart rate, and the best one for you will depend on your specific needs and preferences. Here are some popular options:

1. Smartwatches: Smartwatches like the Apple Watch, Garmin Forerunner, or Fitbit Versa have built-in heart rate monitors. They provide continuous heart rate tracking, including resting heart rate, active heart rate, and heart rate zones. They also offer additional fitness and health features.
2. Fitness trackers: Devices like Fitbit Charge, Garmin Vivosmart, or Samsung Gear Fit are dedicated fitness trackers that include heart rate monitoring. These wristbands offer continuous heart rate tracking, sleep tracking, step counting, and other basic fitness features.
3. Chest strap monitors: Chest strap heart rate monitors like Polar H10 or Wahoo Tickr provide extremely accurate heart rate readings. They use electrodes attached to a chest strap, which wirelessly transmit heart rate data to a compatible device like a smartphone or fitness watch.
4. Armband monitors: Armband heart rate monitors like Scosche Rhythm+ or Mio Alpha ******** your upper arm and use optical sensors to monitor your heart rate. They offer a comfortable and less restrictive alternative to chest straps.

Ultimately, the best fitness product for tracking heart rate depends on your preferences, intended use (e.g., running, cycling, general fitness), budget, and the additional features you desire. It is recommended to read reviews, compare features, and consider your specific needs before making a decision.
