In January 2005, the U.S. government released a new set of dietary guidelines essentially telling us that as Americans get bigger, so does the length of time we need to be physically active.
While it's a little more involved than that, the guidelines from the Department of Agriculture and the Department of Health and Human Services indicate that at least 30 minutes of daily physical activity is required to reduce the risk of chronic diseases in adulthood. And for some, that's only the beginning.
"The dietary guidelines committee primarily focused on the role of physical activity in influencing energy balance and weight status," says Russell Pate, PhD. Pate was a member of the dietary guidelines advisory committee.
"We felt that it was important to reaffirm the 30 minutes of exercise every day guideline as applicable to all adults," says Pate, "but also go beyond that and focus on people who tend to gain weight anyway even if they are meeting that 30-minute threshold."
Thirty minutes of exercise every day? And in some cases, even more? While it might not be music to your ears, it is health to your body.
"Poor diet and physical inactivity, resulting in an energy imbalance (more calories consumed than expended), are the most important factors contributing to the increase in overweight and obesity in this country," according to the guidelines.
It's not like we haven't heard it before: Exercise is an essential part of the health equation, and 30 minutes a day is where it begins.
"Thirty minutes of physical activity is across the board to all adults, every day of the week," says Pate, who is a professor at the Arnold School of Public Health at the University of South Carolina. "There is enormous scientific information to support this."
Meeting the 30-minute threshold will help a person maintain a healthy weight and reap health benefits like lowering the risk of heart disease, osteoporosis, diabetes, and hypertension, according to the guidelines.
From there, the amount of physical activity a person needs climbs, depending on his weight status.
"For those who are following the 30-minute guideline and gaining weight anyway, they may need as much as 60 minutes a day to prevent weight gain," says Pate.
And at the high end of the spectrum is 90 minutes of exercise every day.
"The 90-minute recommendation is for people who have been significantly overweight, lost a substantial amount of weight, and seek to maintain that weight loss in the long term," Pate tells WebMD. "Data from the National Weight Loss Registry indicates that people who have been overweight succeed in losing and maintaining weight loss for an extended period if they are highly active during the period when they are maintaining the loss."
Ninety minutes is the bottom line for people in this category, although some might comment that most people aren't even doing 30, so why would they do two or three times that?
"It looks different, and dramatic and potentially controversial," says Pate. "But whether you like the facts or not, it's important to base the recommendation on the best science available."
While these new guidelines may be a frightening thing in the face of a busy lifestyle, they're not far off from where we've been.
"The 2005 dietary guidelines really spell out for us what we've been told along," says Cedric Bryant, PhD, chief exercise physiologist for the American Council on Exercise.
In 1996, explains Bryant, the U.S. surgeon general issued a position that Americans should strive to obtain 30 minutes of moderate physical activity on most days. While some might have interpreted that to mean three days a week -- a common misconception -- the science has always indicated more than that was necessary to maintain weight and promote health.
In 2002, the Institute of Medicine upped the ante by saying Americans needed to accumulate even more physical activity if they wanted to effectively control weight.
"The 2005 guidelines put all this together and refined the information," says Bryant, "basically saying you want to strive to get in as much physical activity as you can on most days: 30 minutes a day if you're a person of normal body weight and you just want the health benefits of being physically active, 60 minutes if you want to control your weight, and 90 minutes if you want to lose and sustain."
So Americans need to make time to exercise and find a way to work the recommended amount of physical activity into a busy schedule, whether its 30 minutes or 90. The good news: you can do it in bits and pieces.
"The effects of exercise are cumulative," says Bryant. "It doesn't have to be done all at once. It's like loose change in your pocket -- it all adds up at the end of the day and meets the threshold."
So while you don't need to spend hours at the gym every day, you do have to get the heart pumping.
"Whatever activity it is, you need to move your body to the degree that it's making you breathe faster or harder," says Rick Hall, a registered dietitian and advisory board member for the Arizona Governor's Council on Health, Physical Fitness, and Sports.
And since the new guidelines state you should have physical activity on "most days," what happens if you miss a day?
"Theoretically, you can't make up for lost time if you miss a day of exercise," says Hall. "But in reality, energy balance means that if you burn more calories on the other days, you will in a sense make up for it."
But the bigger problem for most people, explains Hall, is falling off the exercise wagon, and never getting back on.
"Most people get out of their routine, and give up," says Hall. "So when you miss a day, don't try to pack more into your next workout so that you feel so overwhelmed that you never exercise again. At the very least, squeeze some push-ups or sit-ups in at the end of the day, and get back into your routine the next."
So when it comes to the recommendation of 30-90 minutes of physical activity on most days -- can it possibly be done? Yes, if you make it a priority.
"You can do this," Hall tells WebMD. "You have to make it a priority. Most people can incorporate these recommendations into their lives, no matter how busy they are. But it's something you have to want to do."
Here are some suggestions for becoming physically active:
From there, Pate explains that you can determine whether the 60- or 90-minute recommendation is right for you.
"If you meet the 30-minute guideline consistently for an extended period and gain weight anyway, you are one of the people who needs more than that to maintain energy balance," says Pate. "This all comes down to the individual, and how they act on the guidelines."
The guidelines are updated every five years, as required by law. So until 2010 when a new set is announced, the 30-60-90-minute rule is in effect, and Americans need to find their threshold and work it in to their daily lives.
While a new set of guidelines might change that number -- for better or worse, depending on how you look at it -- the current goal is: "Balance energy and weight status," says Pate. "And, make it fun. Meet your goals in a way you enjoy."
EVEN though her son and daughter were on year-round swim teams, Alison van Diggelen of San Jose, Calif., had reservations about letting them sign up for a children’s triathlon. Would they have the stamina? Would the other children and parents be too competitive?
LONDON (Reuters) – Britain on Friday condemned celebrations in Tripoli to mark the return of the Lockerbie bomber, and scrambled to deflect international fallout from the decision to free him on humanitarian grounds.
"The sight of a mass murderer getting a hero's welcome in Tripoli is deeply upsetting, deeply distressing, above all for the 270 families who grieve every day for the loss of their loved ones 21 years ago," British Foreign Secretary David Miliband told BBC Radio.
"How the Libyan government handles itself in the next few days will be very significant in the way the world views Libya's re-entry into the civilized community of nations," he added.
Miliband dismissed claims that the British government had wanted Megrahi to be freed to bolster diplomatic and commercial ties with Libya and was content to let Scotland's devolved government take the blame for an unpopular decision.
"That is a slur both on myself and the government," he said, adding that no pressure had been put on the Scottish government.
Former Libyan agent Abdel Basset al-Megrahi was serving a life sentence as the only person convicted of bombing Pan Am flight 103 over the Scottish town of Lockerbie. The bombing killed 270 people, 189 of them American.
Washington described the release as a mistake.
Frank Duggan, president of Victims of Pan Am 103, a group representing families of U.S. victims, said he understood Libya had promised Megrahi would not "go back to a hero's welcome."
"There is going to be no dancing in the end-zone, as the expression goes," he told Reuters on Thursday.
More than 1,000 young Libyans gathered at an airport in Tripoli to welcome Megrahi and cheered and waved national flags as his car sped away. Pictures of the blue and white Scottish flag being waved were shown on British television.
Large public gatherings are rare and are usually tightly controlled in Libya.
GADDAFI'S SON THANKS BRITAIN
State media had made no mention of Megrahi's possible return but a newspaper close to leader Muammar Gaddafi's reformist son, Saif al-Islam, was following his progress.
Islam, who accompanied Megrahi back to Libya, promised last year to work for Megrahi's release and praised the British and Scottish authorities in words likely to add to their discomfort.
"I also personally thank our friends in the British government as they have had an important role in reaching this happy conclusion," he said in a statement.
"I affirm that the Libyan people will not forget this brave stance from the governments of Britain and Scotland and that friendship between us will be enhanced forever. The page of the past has been turned and is now behind us," he added.
The crowd that greeted them at Tripoli's Mitiga airport, a former U.S. air base, were mostly members of Libya's National Youth Association which is close to Gaddafi's son.
Alex Salmond, head of the devolved Scottish government, condemned the celebrations.
"I don't think the reception for Mr al-Megrahi was appropriate in Libya, I don't think that was wise and I don't think that was the right thing to do," he said.
The case has added to tensions between the devolved government led by the separatist Scottish National Party and the British government led by the Labour party.
How many times have we heard that women should not lift weights? I know I still talk to women that are deathly afraid of lifting anything heavier than 3 lbs for fear of looking "blocky" or muscular. All of these fears are completely unfounded and need to be abolished. There is no research that can show women put on significant amount of muscle from an intense weight lifting regimen. In fact, there are so many arguments in favor of this practice, the old-time myths should be old legends by now. It takes years and years of hard, consistent training to add a few pounds of muscle for women. Heck, it takes men years of training, too, and they are hormonally advantaged in this respect! Here is a great article I found from Stone Fitness in Australia.... Damon
Over the last decade, researchers have made extremely compelling arguments for the benefits of weight training for women and those over the age of fifty.
Still, the number of women who take this recommendation to heart is still quite low. Most women who exercise are spending most of their gym time on cardiovascular exercise. Whatever your reasons for avoiding the weights, if you are a woman, here are ten reasons why you need to take strength training seriously.
You Will Be Physically Stronger.
Increasing your strength will make you far less dependent upon others for assistance in daily living. Chores will be easier, lifting kids, groceries and laundry will no longer push you to the max. If your maximum strength is increased, daily tasks and routine exercise will be far less likely to cause injury. Research studies conclude that even moderate weight training can increase a woman's strength by 30 to 50 percent. Research also shows that women can develop their strength at the same rate as men.
You Will Lose Body Fat.
Studies performed by Wayne Westcott, PhD, from the South Shore YMCA in Quincy, Massachusetts, found that the average woman who strength trains two to three times a week for two months will gain nearly two pounds of muscle and will lose 3.5 pounds of fat. As your lean muscle increases so does your resting metabolism, and you burn more calories all day long. Generally speaking, for each pound of muscle you gain, you burn 35 to 50 more calories each day. That can really add up.
You Will Gain Strength Without Bulk.
Researchers also found that unlike men, women typically don't gain size from strength training, because compared to men, women have 10 to 30 times less of the hormones that cause muscle hypertrophy. You will, however, develop muscle tone and definition. This is a bonus.
You Decrease Your Risk Of Osteoporosis.
Research has found that weight training can increase spinal bone mineral density (and enhance bone modeling) by 13 percent in six months. This, coupled with an adequate amount of dietary calcium, can be a women's best defense against osteoporosis.
You Will Improve Your Athletic Performance.
Over and over research concludes that strength training improves athletic ability in all but the very elite athletes (See Article). Golfers can significantly increase their driving power. Cyclists are able to continue for longer periods of time with less fatigue. Skiers improve technique and reduce injury. Whatever sport you play, strength training has been shown to improve overall performance as well as decrease the risk of injury.
You Will Reduce Your Risk Of Injury, Back Pain and Arthritis.
Strength training not only builds stronger muscles, but also builds stronger connective tissues and increases joint stability. This acts as reinforcement for the joints and helps prevent injury. A recent 12-year study showed that strengthening the low-back muscles had an 80 percent success rate in eliminating or alleviating low-back pain. Other studies have indicated that weight training can ease the pain of osteoarthritis and strengthen joints.
You Will Reduce Your Risk of Heart Disease.
According to Dr. Barry A. Franklin, of William Beaumont Hospital in Royal Oak, Michigan, weight training can improve cardiovascular health in several ways, including lowering LDL ("bad") cholesterol, increasing HDL ("good") cholesterol and lowering blood pressure. When cardiovascular exercise is added, these benefits are maximized.
You Will Reduce Your Risk of Diabetes.
In addition, Dr. Franklin noted that weight training may improve the way the body processes sugar, which may reduce the risk of diabetes. Adult-onset diabetes is a growing problem for women and men. Research indicates that weight training can increase glucose utilization in the body by 23 percent in four months.
It Is Never Too Late To Benefit.
Women in their 70s and 80s have built up significant strength through weight training and studies show that strength improvements are possible at any age. Note, however, that a strength training professional should always supervise older participants.
You Will Improve Your Attitude And Fight Depression.
A Harvard study found that 10 weeks of strength training reduced clinical depression symptoms more successfully than standard counseling did. Women who strength train commonly report feeling more confident and capable as a result of their program, all important factors in fighting depression.

Today, the American College of Sports Medicine published a memo addressing some myths that are commonly reported in commercial "fitness" magazines...
Message Points: Exercise and Energy Balance
Exercise and Weight Management
1) There is strong evidence from the majority of the scientific literature that physical activity is an important component of an effective weight loss program.
2) Physical activity is one of the most important behavioral factors in weight maintenance and improving long-term weight loss outcomes. In fact, participation in an exercise program has proven to be the very best predictor of maintaining weight that was lost.
3) Effective weight loss and maintenance depend on a simple equation called energy balance: Calories expended through physical activity and normal lifestyle functions must exceed calories consumed.
4) It is a myth that exercise can actually prevent weight loss by leading exercisers to overeat. Research and common sense disprove this notion. Look around the gym or the jogging trail. If this were the case, wouldn’t those who regularly exercise be the fattest?
Other Benefits of Exercise
1) Exercise and physical activity have been proven to help prevent chronic conditions such as heart disease, osteoporosis, anxiety, depression, obesity and diabetes.
2) Studies show that when students are more active (through physical education,
classroom activity, play, etc.) they improve test scores and attendance and experience fewer discipline problems and sick days.
Policy and economic implications
1) Physical activity and exercise are key components of workplace wellness programs, which have been shown to return $2.90 to $5.96 in cost savings for every dollar invested by the employer. Participants in workplace wellness programs have reduced absenteeism, error rates and health care costs; they feel more alert, have better rapport with co-workers, and enjoy their work more.
2) Physical activity and exercise must play a vital role in health system reform. Cost savings from healthy lifestyles can help fund broader coverage for the underserved.
3) Stimulus funds designated for electronic medical records should include fields to record each patient’s physical activity level. Exercise IS medicine and should be measured as a vital sign like blood pressure or cholesterol levels.
4) Reimbursement for services such as healthy lifestyle counseling or clinical exercise physiologists could go a long way toward improving health and reducing health care costs.
5) Physical activity needn’t involve expensive equipment, gym memberships or team athletics. Simple activities like walking, accumulated in 10-minute bouts, can have significant benefits.
6) Communities can do much to encourage physical activity by developing bike paths and walking trails, encouraging walkable neighborhoods, opening school facilities to afterschool activities, and enacting other exercise-friendly policies.
