Would your friends lie to you? They just might be...
This time of year is all about starting fresh—new goals, solid plans, better habits. You probably have a new exercise routine to help you reach your weight loss and fitness goals. Along the way, whether in the gym, reading the latest books, or talking with your friends, you’ll hear a lot of advice about exercise—not all of which is true.
There are several common misconceptions about exercise and weight loss, but don’t let yourself be fooled! Here are the Top 6 Fitness Myths and the Truths that debunk them:
Myth #1: You can take weight off of specific body parts by doing exercises that target those areas.
Truth: This concept is called "spot training" and unfortunately, it doesn’t burn fat. When you lose weight, you are unable to choose the area in which the reduction will occur. Your body predetermines which fat stores it will use. For example, doing sit-ups will strengthen you abs but will not take the fat off of your stomach. Similarly, an activity like running burns fat all over your body, not just your legs. You can, however, compliment a balanced exercise program with a selection of weight training exercises to gradually lose weight and tone the body.
Myth #2: Women who lift weights will bulk up.
Truth: While on a weight lifting program, the right hormones (testosterone) are necessary in order to bulk up. Women’s testosterone levels are much lower than men’s, so in most cases, they are not capable of building large muscles. In fact, since muscle takes up less room than fat, women tend to lose inches when they strength train. So in addition to the physical benefits (increased metabolism, decreased risk of osteoporosis, increased strength), strength training will help you slim down too!
Myth #3: If you can’t exercise hard and often, there’s really no point.
Truth: Even moderate activity is shown to reduce your risk for heart disease and stroke. If you don’t have 30 minutes in your day to exercise, try splitting it up into 10-minute segments instead. Everyone can find 10 minutes to spare sometime during the day! There are simple things you can do to increase your activity without having to go to the gym: take the stairs instead of the elevator, jump rope or do body weight exercises (push ups, crunches) at commercial breaks, take a short walk after lunch. Remember that any exercise is better than none!

We burn a higher percentage of fat when exercising at lower intensities but the total fat burned is often less. Think of it as money. Would you rather have 75% of 100 dollars or 50% of 300 dollars? Translate that to fat and you burn 75% of your calories from fat or 75 calories vs. 50% of your calories or 150! Burning at a higher percentage will net you a lot less fat in the long run, assuming you exercise for the same amount of time. I will take 50% of 300 any day! - 11/14/2010 7:00:07 PM
Someone made the statement that 'if you are not burning fat then you are burning muscle, and nobody wants that'. That is an incorrect assumption. You are still getting a proportion of your calories (energy) from fat when you are not in the fat burning zone, other energy sources include carbs and stored glycogen. If you are burning more calories overall, you will burn more fat (even though the PROPORTION of calories from fat is lower). Burning more calories, no matter where they come from, will lead to better weight loss (as long as you don't eat them all back).
Here is a good explanation that should clear up some of the confusion: http://scienceblo

OZWODEN - with respect to #5.
The problem with doing longer lower intensity exercises is that your because you burn such a high percentage of fat, your body will tend to store more fat as a protection mechanism.
This type of strenuous workout, without rest, mimics prolonged stress. It also causes your body to adapt in a way that is counterproductive to your health and longevity.
For all your effort, you only reduce your ability to handle life’s demanding circumstances – and that’s the last thing you want. With less reserve heart capacity available on call, you invite trouble when a stressful situation arises.
During long-duration exercise, your heart is under constant stress with no time to rest and recover. When this goes on long enough, the heart is traumatized.
Endurance exercise causes your heart and lungs to adapt for endurance. But these organs are already endurance machines. Your heart beats continuously and your lungs expand and contract with every breath you take. Forced, continuous, endurance exercise prompts your heart and lungs to “downsize.” Reducing to smaller capacity allows you to go further, more efficiently, and with less rest and less fuel.
Our ancestors didn’t run marathons or jump around for an hour doing aerobics. And they didn’t sit in front of computers or the television the entire day. They moved around a lot at a low level of exertion. And then every once in a while they exerted themselves at nearly 100% of their capacity – hunting prey or escaping from it.
This pattern of brief intense movement, followed by rest, and lots of low level activity is hardwired in your genes. Your muscles, bones and organ systems are reflections of this genetic design. The way they work together is the formula for strength, vitality and long life. - 5/18/2010 7:26:56 AM
