For most people the purpose of walking is to burn calories, become trim, give shape to their body, increase their stamina & increase the flexibility of joints and muscles. These objectives sometimes help in relieving pains & aches in various parts of body.
It might interest you that by walking you will burn almost 100 calories per mile if you are an average weighted person (150 pounds or about 70 Kg). If you are overweight you may burn more calories. Heavy weight persons have to watch out that they don’t get hurt while walking and they should also watch their speed of walking to avoid injuries & fatigue and exhaustion.
