Like a lively puppy that is thriving, joyously active and everywhere at once, Let's Move! has energized America with no sign of slowing down. In just a year, First Lady Michelle Obama's initiative has prompted families, individuals and organizations to take health into their own hands. Collectively, we're eating better and finding ways to be more physically active. It adds up to healthier lifestyles for a whole spectrum of people and reflects encouraging momentum in the fight against childhood obesity.

As more and more of us connect the dots - through Let's Move!, the National Physical Activity Plan, Exercise is Medicine (EIM) and countless other initiatives - we're helping the movement mature. Recounting success stories and lessons learned lets us share best practices. EIM on Campus connects colleges and universities with one another, but also with their local communities. Groups like the National Society of Physical Activity Practitioners in Public Health allow professionals to learn from one another and share resources.

We're learning not only from one another, but from new research about exercise, nutrition, physiology and motivation. This is essential to make sure our programs and policies will be effective. From molecular-level, basic science to studies of group interaction and epidemiology, new knowledge is providing a solid base of evidence to underpin our efforts.

Similarly, approaches to healthier lifestyles range from the granular to the global. We know that every bite we consume, every calorie expended, brings with it a health impact. Individual actions become habits, with immense effects on individuals over time. Family members influence one another, and whole communties can gain a collective consciousness or identity around healthy lifestyles (think Portland, Oregon, where bicycling is a shared passion).

A spectrum of solutions

Some of us emphasize physical activity and exercise, but we know that's just one factor in the health equation. Nutrition plays a huge role, as do tobacco and alcohol use, air quality and more. We've learned that all these elements must work together, and that healthy behaviors must become part of our everyday lives to be effective. And their adoption requires the kind of one-on-one modeling that happens in families, classrooms and circles of friends - but also the collective action that is reflected in organizational and community policies.

The vision reflects the range of benefits, from individual health and quality of life to societal gains in worker productivity and reduced health care costs. We're getting there, thanks to a growing foundation of research, immeasurable individual effort, and the unstoppable enthusiasm of initiatives like Let's Move.

How do your efforts complement the work of Let's Move!, the National Physical Activity Plan and other initiatives?

How can we activate more people to "think globally; act locally" to foster healthier lifestyles?

It's a wonderful time to be in the business of promoting physical activity. There aren't many issues in the public policy arena that enjoy such a broad consensus of support across political, social, and cultural lines. Everyone agrees that physical activity is good, regular physical activity is better, and a physically active lifestyle is best!

But it is a challenging time in Washington, DC and across the nation - with dwindling public health dollars, austere budgeting, "nanny state" push-back, and the need to accomplish more with fewer resources. That is why it is more important than ever that people, organizations, government agencies, industries, and others who are interested in promoting health and wellness must come together. We need to present consistent, unified messaging, coordinate our resources, and collaborate across various sectors to create healthier environments and policies that allow people to make healthy choices.

In our efforts to implement the National Physical Activity Plan, the National Coalition for Promoting Physical Activity has built a network of individuals working across eight different sectors - including education, public health, business/industry, health care, parks and recreation, and transportation - to implement the strategies and tactics laid out in this important road map. These strategies drive specific policies and programs aimed at getting people up on their feet and moving.

Business & Industry Sector

In the business and industry sector, we are working to identify, collect, and make available the best practices, models, and existing programs for physical activity in the workplace. The sector team has developed a CEO Pledge, urging corporate leaders to commit themselves and their companies to provide opportunities and access for their employees to be active before, during, and after the work day. These businesses will gain access to a valuable resource list to help shift their corporate cultures from sedentary to physically active work environments.

Education Sector

One of the education sector's strategies is to promote policies to provide access and opportunities for physical activity in after-school programming. The sector team conducted a survey to compile information on standards and guidelines for afterschool activity. They gathered data from 500 programs in 10 regions, and also looked at school districts with diverse demographic profiles. In fact, this year marked the first development and adoption of National Standards on Nutrition and Physical Activity for Afterschool Programs.

Health Sector

The health sector is working to make physical activity a "vital sign" that all health care providers assess and discuss with patients. The team is working to establish physical inactivity as a treatable and preventable condition with profound health implications. They are also developing policies to include physical activity in the education and training of all health care professionals.

The Federal government by nature of its broad reach can lead the cultural shift. The same folks who put Rosie the Riveter to work in the factories now need to help Rosie get off the couch and make the move to a physically active lifestyle. Physical activity needs to be inserted into the health policies of the entire government.

To reach the ultimate goal of creating a society of physically active children and adults, we all need to use a common voice when bringing our ideas and energy to the effort. There's something for everyone in the National Physical Activity Plan. What are you doing to help put the plan into action?

The National Physical Activity Plan is a multi-sectoral blueprint for creating a more robust culture of physical activity. It's appropriately aspirational, but grounded in practical objectives. Much like Healthy People 2020, it's great strength is its ability to unite powerful forces of change around common goals.

But the magnitude of the project - creating a cultural shift of national proportions - can feel overwhelming. So many changes need to be made in so many places. Real, measurable progress seems difficult to identify.

But like the journey of a thousand miles that begins with a single step, maybe cultural shifts of national proportions can begin with a single county.

And that county may be Greenville, South Carolina.

The folks of Greenville have created Livewell Greenville, a partnership of dozens of public and private organizations that aims to make Greenville County a healthier place to live, work, and play.

The approach of Livewell Greenville is to not only provide educational resources about healthy living, but also to create policies, systems and environments that make the healthy choice the easy choice.

The initiative focuses on seven societal buckets: at school, before and after school, at work, at the doctor, at mealtime, around town, and "for fun."

The following Livewell Greenville goals relate to physical activity:

• Provide tools to teachers to encourage physical activity during learning and throughout the day.
• Encourage more childcare providers to serve healthy meals and snacks and offer regular structured physical activity in licensed childcare centers.
• Encourage more after school providers to serve healthy meals and snacks and offer regular structured physical activity in non-licensed after school programs.
• Incentivize after school programs and childcare centers to adopt policies that support healthy eating and active living among children.
• Increase the number of work places that adopt policies and environments that support employees in staying physically active and eating healthy, nutritious food.
• Encourage health care providers to provide patients with practical referrals for healthy eating, active living, and treatment for obesity.
• Enable residents to run errands and commute on foot, by bike, or on Greenlink.
• Enable more Greenville County children to walk to school safely.
• Encourage neighborhood groups and residents to become more involved in the transportation planning process.
• Increase safety through Park Watch programs.
• Increase access to basic recreation facilities through the development of a model Complete Parks policy.
• Increase accessibility to local parks.
• Increase awareness of local facilities where residents can play and be active.

My hope is that Livewill Greenville will inspire thousands of similar community-based efforts around the country. Surely, duplicating the initiative would not be easy, and Livewelll Greenville benefits from the talents of dedicated community champions willing to invest significant time to make the initiative meaningful, but I'm willing to bet that every community has champions who are up for the challenge. Maybe every community won't succeed, but given what's at stake, it's certainly worth a try.
