Whether you are just starting a fitness program or are an experienced athlete, you can greatly benefit from paying attention to your heart rate during exercise. Heart rate serves as a window into the body, giving you minute-to-minute feedback on your physical condition based on all the factors affecting it - exercise intensity, diet, temperature, humidity, altitude, fatigue, and more.
To build fitness and control the level of intensity in your workouts, a heart rate monitor is the best tool. Heart rate monitors (HRM) can come with lots of functions. Look for one that does what you want and need.
You can get more benefit out of the time spent exercising. The 3 most important variables of your fitness program are Frequency, Duration and Intensity. The first two are easy to monitor but intensity is the most elusive.
A heart rate monitor (HRM) gives you the information on exercise intensity. It gives you an accurate heart rate measurement into your body’s response to the moment to moment changes in physical activity.
It ranges from a minimum value when you are resting to a maximum level during hard exercise.
