Don't Let These Myths Sabotage Your Success

Myth #3: Running or Walking on the Treadmill is as Good as Running Outside
I heart the treadmill. Treadmills allow you to run at a variety of paces and inclines while avoiding any nasty weather. However, if you're preparing for a running race or walking event, you need to know that the treadmill does not challenge you as much as doing the same activity outside. In fact, the motion of the treadmill belt actually slightly helps pull your feet back, thereby allowing you to shorten your running and walking stride and put forth less energy. Less energy means fewer calories burned. In addition, the treadmill is set at a totally flat or slight decline, which also makes your run or walk easier than it is in the great outdoors. Therefore, if you're used to running or walking on the treadmill, you'll be in for a big wake-up call when you head outside and find that you can't run as fast or as long without becoming winded.
Action tip: Change your scenery. Once a week, trade your indoor workout for a power walk or jog through your neighborhood or a park. The change of scenery will help give your body and your mind something new to focus on. As your muscles work harder to propel your body (without the help of a moving belt), you'll burn more calories and better gauge your true running or walking speed. If outdoor workouts aren't an option for you, add incline to your treadmill to help offset momentum of that treadmill belt.
Myth #4: You Should Change Your Workout Intensity Based on the Heart Rate Display
The built-in heart rate monitors on cardio equipment sure are handy. After all, they sense your pulse (heart rate) from your fingertips and hands! However, your pulse isn't as strong or accurate when measured from your hands as it is when it's measured closer to your chest. Plus, these displays rely on sporadic data, which is only available when you hold on to the console or handles. This is typically a bad idea, especially if you're running or walking fast or if holding on compromises your form or causes you to lean into your hands—a sure sign that you're not really working as hard (or burning as many calories) as you may think.
Action tip: Listen to your heart. Consider investing in a heart rate monitor with a chest strap. These are the most accurate and reliable ways to measure your exercise intensity continuously and safely as you work out—without compromising your form. If a heart rate monitor isn't in your budget yet, use the Rate of Perceived Exertion or the Talk Test to measure your exercise intensity. You'll find details on these methods and more in our Reference Guide to Exercise Intensity.
Above all, remember that when it comes to exercise—on the cardio machines or not—everyone is different and no machine can really be accurate for everyone. Some are more accurate than others are, but always listen to your body and continue to track your workouts on SparkPeople's Fitness Tracker. After all, you know yourself best—and that's no myth!
