Walking on hills or sand demands more effort than on flat ground. The body type also plays a role. People with more muscle mass burn calories faster, even at rest. ●Strengthen the heart. Walking quickly helps strengthen the heart by increasing the heart rate and improving blood circulation. 6 Walking is an easy way to increase physical activity and is known to help prevent and manage heart disease for those with heart problems or at risk of developing them. ●Help lower high cholesterol(胆固醇)and blood sugar.
