Walking: Improve your health and trims your waistline.

Thirty percent of American adults walk for exercise.

Walking eases fatigue and improves mood in those with Parkinson's disease.

Mild to moderate Parkinson's disease may improve their motor function, mood, fatigue levels and more by taking regular aerobic walks.

The researchers concluded that people with mild to moderate Parkinson's disease could benefit from following the federal guidelines recommending 150 minutes a week of moderate aerobic activity for people ages 18 to 65.

For example, regular brisk walking can help you:

• Continue a healthy weight.
• Prevent or manage various conditions, including heart disease, high blood pressure and type 2 diabetes.
• Strengthen your muscles and bones.
• Mood booster
• Improve your coordination and balance

Adding 150 minutes of brisk walking to your routine each week can add three to four years to your lifespan. The faster, farther and more frequently you walk, the greater the benefits.
