Basically, a heart rate monitor enables you to keep track of how
hard your heart is working during exercise. A chest transmitter,
using moistened electrodes, measures the
electrocardiogram (ECG) signal from your heart. This signal is
then transmitted to and displayed on a wrist monitor, which looks like
a typical wristwatch. In face, the electrocardiogram device
used by medical personnel performs similar functions to a fitness style
heart rate monitor, but it measures the electrical impulses of the heart
in a more sophisticated manner.
Reaching Your Fitness Goals
In order to reach your fitness goals, the first step is determining
your maximum heart rate. How do you do this? By subtracting
your age from 220. If you are 40 years old your maximum heart
rate is 220-40, or 180. Once you know your maximum heart rate,
you can then determine where your heart rate range should be in order
to achieve your goals. These can be programmed into your heart
rate monitor, which will alert you via signal if you fall below or go
As a rule of thumb, beginners who wish to increase fitness or
lose weight should exercise at 50 to 60 percent of their maximum heart
rate. Regular exercisers who want to lose body fat should exercise
at 60 to 70 percent of their maximum heart rate. People who wish
to improve their aerobic fitness should exercise at 70 to 80 percent of
their maximum heart rate, while competitive athletes who need to add
interval sessions may need to exercise at 80 to 90 percent of their
maximum heart rate.
