Which of the following can be used to calculate heart rate?

You can calculate your heart rate using various methods! One of the most common ways is to take your pulse either on your wrist or neck—just count the beats for 15 seconds and multiply that number by four. Voila, you’ve got your beats per minute (BPM)! Another cool tool is a heart rate monitor, which can strap onto your chest or wrist, giving you a continuous reading while you bust a move at the gym! Speaking of gym time, tracking your heart rate isn’t just for workouts; it also helps you understand your overall fitness level! For instance, knowing your resting heart rate can inform you how aerobically fit you are: a lower resting rate usually means a more efficient heart! Many fitness apps can track this for you, making heart rate monitoring a fun part of your fitness journey.
