Your heart is the most important trainable muscle in your body. It is
easily taken for granted and neglected, which leads to disease and premature
ageing.
Depending on your age, you have a personal "training zone", often referred
to as your "target heart rate". It is a level of activity high enough
to provide sufficient exercise to strengthen the heart, but not uncomfortably
high ( and possibly dangerous for someone who is unfit). In most cases, the
ideal level is between 70-85% of your maximum heart rate.
How to calculate your target heart rate
You can calculate and monitor your target heart rate by using the following
formula. This is a very simple thing to do and will provide you with a personal
target for your training, which should help your motivation.
The formula
For the beginner exerciser:
220 minus your age multiplied by 60%
For the regular exerciser:
220 minus your age multiplied by 70%
For the advanced exerciser:
220 minus your age multiplied by 85%
(You can also refer to the chart)
If you have Internet Explorer 4 and later, and the
Excel web site component on your computer, enter your age into the first box for
the calculations done for you.

Taking your pulse
To keep your heart within your target heart-rate zone you need to know how to
take your own pulse. This can be done by touching your wrist or the carotid
artery on the side of your neck; the latter is generally easier during training.
Place your first two fingers on the artery while you exercise and count the
number of beats over 15 seconds. Multiply by four to give the number of beats
per minute: i.e. 30 beats per 15 seconds means you have a heart rate of 120 BPM.
