Heart Rate Programs
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 of your MHR. Your Heart rate training
zone is 50% to 90% of your maximum heart rate. 60% of your MHR is the recommended for
burning fat while 80% is recommended 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.
