Myth #4: Performing abdominal exercises will give you a flat stomach.
Truth: This is similar to Myth #1 above. The fact is, the only way to get a flat stomach is to strip away the fat around the midsection. This is accomplished by doing cardio/aerobic exercise (to burn calories), strength training (to increase metabolism) and following a proper diet. Abdominal exercises will help to build muscle in your midsection, but you will never see the muscle definition unless the fat in this area is stripped away.
Myth #5: Since you burn more fat if you exercise at a lower intensity, you want to keep your wokout in this "zone".
Truth: The most important factor in exercise and weight control is not the percentage of fat calories burned, but the total calories burned during the activity. The faster you walk, bike or swim, for example, the more calories you use per minute. Although you will be burning fewer "fat calories", you will be burning more total calories, and in turn, will lose more weight.
Myth #6: No pain, no gain!
Truth: Exercise should not be painful! At the height of your workout, you should be sweating and breathing hard. You should not be so out of breath that you cannot answer a question, but should not be so comfortable that you can carry on a full conversation. That’s how you know you are working at a good level. It’s important to distinguish between muscle fatigue (feeling "the burn") and muscle/joint pain (sharp and uncomfortable pain during movement). Pain is your body’s way of telling you that you’re doing something wrong. Listen to your body. If it’s painful, stop!
