To Lose Weight and Get in Shape Faster

You Could Use a Pacemaker

Electrocardiogram

By Terry Dunkle, DietPower Editor-in-Chief

By pacemaker I don’t mean an electronic implant, but something that helps you get in shape faster by controlling your pulse during exercise. You can pay up to $700 for such a device—or make your own.

Studies show that your body selectively burns fat if you exercise in your "Target Zone," where exercise is strenuous enough to condition your heart and lungs, but not to give you bulging muscles.

Where is your Target Zone? It's the sweet spot between 60-percent and 85-percent of your maximum heart rate. If you keep your pulse there during workouts, you'll rapidly burn fat.

The problem is, you can't find your Target Zone without knowing your maximum heart rate. Worse, your maximum heart rate depends partly on the type of exercise you're doing. And even worse, your Zone changes as your fitness level rises.

The good news is that you can solve all three of those problems instantly with DietPower's new online Target Zone Finder. I urge you to try it (and bookmark it) right now. You won't find a better Target Zone calculator on the Web. Ours considers not only your age (where most other calculators stop), but your resting heart rate, your choice of exercise, your training level, and even your sex. (Men's heart rates peak higher than women's.)

All right, thanks to this nifty new tool, let's say you've found that your Target Zone for medium-intensity walking is 146 to 155 beats per minute, and you're about to go out for a jaunt. How can you stay in your Zone? How can you tell whether you're walking too slow or fast?

Here's where that seven hundred bucks comes in. Or not.

  • For $100 to $700, you can buy a fancy-schmancy monitor to wear during workouts. A sensor in a chest strap radios your heart rate to a unit resembling a wristwatch, which beeps when you stray from the Zone. I tried one of these a few years ago. On the plus side, it helped me get rid of a lot of money. On the minus side, the chest strap drove me crazy. It was not only uncomfortable, but a nuisance to put on.

  • For absolutely zero dollars, you can use the pacemaker you already have: your wristwatch and two fingers. Check your heart rate every five or ten minutes by 1) stopping your workout, 2) pressing an index and middle finger into the crook of your jaw and neck to find your pulse, 3) counting heartbeats for six seconds, and 4) adding a zero. The downside is that you have to stop your workout each time you take a reading. This is not only embarrassing, but inaccurate because your pulse begins slowing the moment you stop.

As a compromise, DietPower has begun offering heart-rate monitors that sit only on your wrist—they don't require you to wear a chest strap. These newer models use the same technology as the electrocardiograph at your doctor's office. They're just as comfortable as a watch. (In fact, they are watches, complete with time of day, stopwatch, countdown timer, and alarm.) They let you take a reading without stopping your workout: you simply press a fingerpad and look at the screen. Two models even estimate the number of calories your workout has burned.
