HEART RATE TRAINING
The old motto, "no pain, no gain", is a myth that has been overpowered by the benefits of exercising
comfortably. A great deal of this success has been promoted by the use of heart rate monitors. With
the proper use of a heart rate monitor, many people find that their usual choice of exercise intensity
was either too high or too low and exercise is much more enjoyable by maintaining their heart rate in
the desired benefit range.
To determine the benefit range in which you
wish to train, you must first determine your
Maximum Heart Rate. This can be
accomplished by using the following formula:
220 minus your age. This will give you the
Maximum heart rate (MHR) for someone of your
age. To determine the effective heart rate range
for specific goals you simply calculate a
percentage your MHR. Your Heart rate training
zone is 50% to 90% of your maximum heart rate.
60% of your MHR is the zone that burns fat
90
while 80% is for strengthening the cardio
vascular system. This 60% to 80% is the zone to
stay in for maximum benefit.
For someone who is 40 years old their target heart rate zone is calculated:
220 – 40 = 180 (maximum heart rate)
180 x .6 = 108 beats per minute (60% of maximum)
180 X .8 = 144 beats per minute (80% of maximum)
So for a 40 year old the training zone would be 108 to 144 beats per minute.
If you enter your age during programming the console will perform this calculation automatically.
Entering your age is used for the Heart Rate control programs. After calculating your Maximum Heart
Rate you can decide upon which goal you would like to pursue.
The two most popular reasons for, or goals, of exercise are cardiovascular fitness (training for the
heart and lungs) and weight control. The black columns on the chart above represent the Maximum
Heart Rate for a person whose age is listed at the bottom of each column. The training heart rate, for
either cardiovascular fitness or weight loss, is represented by two different lines that cut diagonally
