Answer:
heart disease
Step-by-step explanation:
Walking 10,000 steps a day has long been linked to lowering artery diseases/heart diseases. It is said to regulate one's blood pressure level and cholesterol level. If you keep on walking, the heart becomes tuned to such condition, thus, making it stronger. A strong heart enables easy pumping of blood, thereby lowering the blood pressure.
Walking also helps increase the body's high-density lipoproteins (HDL). These are considered the "good cholesterols." This cholesterol is responsible for removing surplus cholesterols found in the blood.
