Once you locate your pulse, look at the time and count the beats for six seconds. Multiply that number by 10 to determine the total number of beats per minute. For example, if you count 14 beats over six seconds, the total number of beats per minute is 140. Compare the total number of beats with your training zone as identified in Diagram 15. If necessary, increase or decrease your activity level to bring your heart rate into your training zone. You can regulate your work level (and heart rate) by changing the belt’s speed or incline level. Remember—your heart rate is the definitive measure of how hard you are working.

Regardless of your fitness level, avoid doing too much too soon. Running or walking too fast or setting the elevation too low are common errors. Give yourself time to become familiar with your treadmill and improve your fitness level. Then you can gradually increase your speed and change the elevation to make your workouts more challenging.

How Long Should I Exercise?

The length of each exercise session depends on your fitness level. Exercise physiologists have determined that, to attain cardiovascular benefits from exercise, you should maintain your heart rate in the training zone for at least

15 minutes. This is in addition to your warm up time and does not include cool down. You should always allow several minutes to warm up and bring your heart rate into your training zone by starting out slowly, and gradually increasing the work level. Similarly, use several minutes of light exercise to cool down after the workout and bring your heart rate down to near resting level.

The higher your fitness level, the longer you should maintain your heart rate in the training zone (between 20 and 30 minutes). Beginners should always start slowly and then, gradually increase their sessions up to 20 minutes or more.

How Often Should I Exercise?

Research indicates that aerobic sessions of 20 minutes or more should be done at least 3 to 5 times a week to obtain significant cardiovascular benefits. Most experts agree that sensible eating habits and regular aerobic exercise are the keys to weight control and fitness. A recent study, which tracked several subjects over a period of years, conclusively shows that exercise, not dieting, is the key factor to successful long-term weight loss.
