You can maintain your desired heart rate by wearing a heart rate monitor. These are small electronic devices that usually resemble a wrist watch. The heart rate monitor will display your current heart rate and allow you the opportunity to either speed up or slow down your running pace in order to stay within what your desired heart rate is.
