5 Reasons Your Workout Isn't Working

Have you been working out consistently for months (maybe even years) and yet the scale is creeping up? Here are five ways your workout could be keeping you from losing weight, and what our experts' recommend to start shedding pounds again:
1. Your workout routine is making you eat too much.
Is your workout causing you to use the "I burned it, I earned it," excuse when it comes to your diet? "Studies show that people tend to eat more calories when they take up exercise ," saysMichele Olson, Ph.D., professor of exercise science at Auburn University Montgomery, and creator of the Perfect Legs, Glutes & Abs DVD.
Think your 45-minute morning run was enough to burn off that slice of chocolate cake on the dessert menu? Consider this: the average, 140-pound woman burns about 476 calories (at a 10-minute mile pace) running for 45 minutes. The average restaurant dessert clocks in around 1,200 calories (or more), so even if you only eat half of a slice, you'd still easily eat away your run-and then some-in less than 10 minutes.
The solution: Make your workouts count by pairing them with a healthy diet that stays within the appropriate calorie range your body needs in order to lose or maintain your weight. Olsonrecommends writing down what you are eating to keep track of calories consumed, and then subtracting the calories you burned, for your true daily number.
2. Your workout completely wipes you out.
That 5:00am killer boot camp class seemed like a great way to get in shape, so why aren't the pounds dropping off? If your workout leaves you feeling completely drained, exhausted, sore, and just wanting to lie on the couch for the rest of the day, it could be doing more harm than good, says Alex Figueroa, a personal trainer and fitness instructor at the Sports Club/LA in Boston, MA. While your workouts should be challenging, pushing your body too hard can have the opposite affect on yourbody. Over training can cause everything from sugar cravings, a weakened immune system, and insomnia-all of which could contribute to weight gain.
The solution: Figueroa recommends following a workout plan that is appropriate for your current fitness level-one that will still challenge your body without completely draining it. Not sure what's best for you? Try scheduling a session with a personal trainer to review your goals and the best plan of action to reach them.
3. Your workout burns fewer calories than you think.
Feeling pretty righteous when the treadmill says you've torched 800 calories? Not so fast, cautionsOlson. An unusually high calorie burn reading is rare, Olson says, and most machines overestimate readings by as much as 30 percent.
"Many machines do not require you to put in your body weight and, therefore, the calorie output is often based on a 'reference weight' often used in science of 155 pounds," Olson says. "So, if you weigh 135 pounds, for example, you would not burn the same calories as someone who is at the reference weight."
And even those that use heart rate readings may not be accurate either. "Machines that incorporate arm activity (such as the stair stepper or elliptical) can cause a higher heart rate compared to a leg-only machine like a treadmill, but this is not usually because you are burning more calories," Olson says. "Research has shown that at the same level of calorie burning, the heart rate will be markedly higher when using the arms versus the legs, and you may even be burning fewer calories despite a higher heart rate."
The solution: Try using a 'distance covered' read-out to more accurately gauge how many calories burnedOlson says. "For instance, if you want to burn 300 calories, jogging 3 miles, walking 4 miles, or cycling about 10 miles on a bike are known to burn this amount."
4. Your workout's not balanced.
Sure, we love Zumba just as much as you do, but that doesn't mean it's all you should be doing to stay in shape. "Variety is not only the spice of life, but the key to getting a better, leaner, stronger body," Olson says. "There is not one single activity that can give you everything you need."
Doing only cardio workouts or the same strength workout over and over means you are sacrificing the opportunity to build lean muscle mass and challenge your body in new ways (translation: burn more calories doing something new), and you may plateau because of it.
The solution: Create a weekly program that rotates through different modalities of exercise (cardio, strength training, flexibility, core) in order to keep your mind, and body, engaged and changing. Olson recommends fitting in at least three strength sessions and three to five cardio sessions per week for best results.
5. Your workout is totally stale.
Have you been taking the same body-sculpting class using the same 3-pound weights week after week? Grab some heavier dumbbells to boost your calorie burn and build more fat-blasting muscle, recommends Sonrisa Medina, group fitness manager for Equinox Fitness Clubs in Coral Gables, Florida. And while you're at it, try a class you've never done (like yoga or Pilates) to stimulate your body in new ways.
Why is it so important to switch things up? Doing the same workout routine over and over means your body doesn't have to work as hard to perform it after a few weeks. "We 'learn' how to do any activity and movements," Olson says. "The more 'learned' we are, the easier the activity is to our bodies, which means you will actually burn fewer calories than you did when the activity or your routine was new to you."
The solution: Whether its trying heavier weights or adding more resistance during cycling class, changing up the intensity and style of your workout can help kick up your calorie burn to start losing weight again. Even adding workouts like yoga and Pilates that don't typically burn a large amount of calories, if they are new to your body, will create some nice changes in your physique simply from being a new challenge to your movement and workout patterns, Olson says.

Home Flu-Proofing Myths, Busted


By Networx.com | At Home 

By Adam Verwymeren,Hometalk
Flu season is in full swing, which means many people will be desperately trying to flu-proof their homes to keep contagions at bay. While people will go to great lengths to keep from getting sick, many of the things we do to purge the home ofgerms are pure myth, and won't actually help. Here are some of the top flu-proofing myths debunked.
Myth 1: A cold, drafty home will cause you to catch cold or flu.
The truth is, there really isn't any correlation between cold and germs, and your body's immune system can handle winter's icy chill, the New York Times reported. Cold and flu season do peak during the winter months, but the correlation probably has more to do with the fact that people spend a lot more time indoors in the winter, making it easier for germs to jump from one person to another. While you can save a bunch of money on your energy bill by sealing up drafts and installing better insulation, unfortunately you won't be insulating yourself from the flu.
Myth 2: You can protect yourself with hand sanitizer.
By offering germophobes the option of purging than hands of pathogens even when a sink isn't handy, alcohol-based hand sanitizers like Purell have taken off in popularity. While these sanitizers will kill germs on contact, there is little indication that they actually decrease the rate of illness, according to several recent studies. The problem is that hand sanitizers clean your hands, but the flu is an airborne virus. The flu spreads when a sick person's cough or sneeze causes little particles of pathogens to take to the air, and you can't scrub those away with a few squirts of Purell.
Myth 3: You can sweat out a cold.
Crank up the thermostat, slip into a hot bath and you'll just sweat out the cold, some people think. While a hot bath might be soothing when you're ill, it won't actually make you better, says ABC News.
Myth 4: You can carpet bomb your house with antibacterial soap to rid it of disease.
Antibacterial soaps, which contain a range of active ingredients like triclosan and sodium benzoate, have long promised to purge our home of illness. The problem, however, is that both cold and flu are caused by viruses, not bacteria. These soaps might work against bacterial infections like staph and E.coli, but have no real effect on viral infections. If you really want to do a number on both bacteriaand viruses, just reach for ordinary bleach.
Myth 5: You can blast away germs with an ultraviolet light.
UV-C sanitizing wands have become a popular disinfectant in recent years. Rather than relying on harsh chemicals, these devices blast germs with a certain type of ultraviolet light that kills them on contact. While UV light systems certainly work on an industrial scale, and have been put to use killing germs in hospitals for more than a hundred years, the small handheld units have little effect, says the L.A. Times. Shining the light on every square inch and around every odd angle of a surface is really difficult, particularly since the commercially-available wands aren't that large. The devices also do little to stop airborne pathogens, which are the main cause of cold and flu.
Myth 6: You can prevent getting a second cold by changing your toothbrush.
There's no need to change your toothbrush after you get sick, says Slate.com. Like snowflakes, every strain of cold or flu is different. But once you're body defeats a particular strain, you're immune, so you can't give yourself the same cold you've already had.

Vitamin D: Who Should Take a Supplement

Vitamin D provides a wide range of health benefits. It is effective in preventing rickets and treating other bone diseases such as osteoporosis. According to the Mayo Clinic, getting enough vitamin D may prevent high blood pressure and protect against certain types of cancer. It may also promote weight loss for women. A growing body of research links heart health to sufficient vitamin D. Most recently, a large-scale study in theAmerican Journal of Cardiology discovered that boosting vitamin D levels in heart patients who were deficient cut their risk of death by 60%, among other significant findings.
Getting enough vitamin D
It's estimated that 30-50% of Americans suffer from vitamin D deficiency. The human body produces vitamin D, which is actually a hormone, when exposed to sunlight. However, during the winter, it is impossible to get enough exposure anywhere north of San Francisco or Philadelphia. People in southern states who slather on sun block or who stay indoors most of the time may not be getting enough either. The same goes for people who are housebound due to illness or whose work keeps them inside all day. In addition to lack of sunshine, other conditions may increase likelihood ofvitamin D deficiency:
Infants who are exclusively breastfed. Mother's milk may not provide sufficient levels. TheAmerican Academy of Pediatrics recommends a supplement of 400 IU per day.
Older adults. The elderly do not synthesize vitamin D as effectively as younger people and tend to spend more time indoors.
People with dark skin. The pigment melanin can reduce the body's ability to produce vitamin D from sunlight.
Obese people. Body fat alters the way vitamin D is released into the system.
Choosing a vitamin D supplement
If you are shopping for a supplement, research suggests that vitamin D3 is more effective than vitamin D2. Food sources rich in vitamin D include cod liver oil, fatty fish (such as mackerel), eggs, and fortified milk and orange juice.
There is some debate over how much vitamin D to take. The National Institutes of Healthrecommends 600 IU per day for adults but some experts say that taking a supplement that contains between 1000-2000 IU can be beneficial. Its important to stay within the appropriate range--there is a toxicity risk at over 10,000 IU. The best way to determine how much you might need is to have your physician administer a simple blood test and make a recommendation based on the current level in you system.
