Heart Zone Training *

How do you know if you are training too intensely or not intensely enough for what you want to achieve? This is where Heart Zone Training comes in. Refer to the chart below. The top of the chart reads "Maximum Heart Rate," which is 100% of your heart rate (the fastest your heart will beat). This is different for everyone. To use Heart Zone Training you must first determine your maximum heart rate (max HR).

You can determine your max HR one of two ways. One way is to use the age predicted max HR formula, whereby you subtract your age from 220. So, if you are 40 years old, your predicted max HR would be 180 bpm. The other method, which is much more accurate and more individualized, is actually having a medical or fitness professional administer a max HR test for you, which is usually done on a stationery bicycle or treadmill for several minutes and requires very hard work. Thus, only those cleared by a physician should do this test. We do not explain how to administer this test because only trained professionals should do so. Please refer to the Global Health and Fitness Personal Training Directory for professionals in your area (may or may not be trained in administering a max HR test).

Once you have determined your max HR, you will need to decide what zone you want to train at. There are five different training zones separated by 10% increments, each having different characteristics and benefits.

Healthy Heart Zone

The first zone is called the Healthy Heart Zone. This is 50-60% of your max HR. This is the easiest and most comfortable zone within which to train and is the one that is best for people who are just starting an exercise program or have low functional capacity. Those of you who are walkers most likely train at this zone. Although this zone has been criticized for not burning enough total calories, and for not being intense enough to get great cardiorespiratory benefits, it has been shown to help decrease body fat, blood pressure and cholesterol. It also decreases the risk of degenerative diseases and has a low risk of injury. In this zone, 10% of carbohydrates are "burned" (used as energy), 5% of protein is burned and a whopping 85% of fat is burned.
