If you are exercising to help in your weight-loss effort you should get a heart-rate monitor. Without one, you won't know if you are burning fat or getting more aerobically fit, or potentially exercising too hard. Knowing your heart rate (or pulse beats per minute) during exercise is critical to exercising efficiently and, ultimately, to weight loss.

During exercise, your heart moves blood from your lungs, where it picks up oxygen, to your muscles, where it burns the oxygen as fuel, and sends it back to your lungs again. The harder you exercise, the more fuel your body needs and the harder your heart has to work to get oxygen to your muscles. The harder your heart works, the faster it beats. This is where a heart-rate monitor comes in.

You need to get your heart rate to a certain threshold to ensure that you are working hard enough and getting more fit. If your heart rate is too low, you're not working hard enough and your body won't benefit as much. If your heart rate is too high, you might be damaging your body. A heart-rate monitor can tell you when your exercise is at the right point. Keeping your heart rate in this so-called target zone is key to burning fat and getting in shape.

Figuring out your target zone is easy. First, figure out your maximum heart rate, which is typically 220 minus your age. (This is a general measurement; more extensive tests are available with your doctor.) Multiply that number by .60 to get the bottom end of the target zone and by .80 to get the top end. Then, stay in that zone throughout for an efficient workout. You burn body fat at the first part of the zone, until about 70 percent of your maximum, you build endurance from 70 to 80 percent.

The key to an effective workout is staying in the zone for at least 20 minutes per exercise session. By the way, your resting heart rate is typically 60 to 80 beats per minute, depending on your level of fitness. Olympic athletes are so fit that their resting heart rate is typically around 30.
