Statistics on Physical Activity

Activity Levels in the US:

• According to the Centers for Disease Control and Prevention (CDC), only about 23% of American adults meet the recommended guidelines for both aerobic and muscle-strengthening activity .
• The CDC also reports that approximately 31 million adults aged 50 or older are inactive, meaning they do not engage in any physical activity beyond their daily routine .

Age Group Comparisons:

• Among adolescents, only about 26% of high school students get the recommended 60 minutes of physical activity every day .
• Physical activity levels tend to decrease with age. About 30% of adults aged 65 and older are physically inactive .

Global Trends:

• Globally, the World Health Organization (WHO) estimates that one in four adults and 81% of adolescents do not meet the recommended levels of physical activity .

Practical Tips for Increasing Walking

Set Realistic Goals:

• Start with small, achievable goals like a 10-minute walk after meals and gradually increase the duration and intensity.

Incorporate Walking into Daily Routine:

• Park further from your destination, take the stairs instead of the elevator, or walk during your lunch break. Make it a challenge.
  

Use Technology:

• Fitness trackers and smartphone apps can help monitor progress and motivate you to reach daily step goals. Compare notes with your friends or family.
  

Make it Social:

• Walk with friends, family, or join a walking group to make the activity more enjoyable and accountable. Walking your dog is a great excuse to get out! Or better yet… make your kids walk the dog to get them out and moving, and tag along!
  

Explore Nature:

• Walking in natural settings like parks and trails can enhance the mental health benefits and make the activity more enjoyable. We call it getting some “Vitamin N” in our office. Can’t replace the power of experiencing nature!
