why do we move our hands while walking?

1. to relieve our tension
2. to walk faster
3. to maintain equilibrium against forceof gravity
4. to increase blood circulation

Before we are starting walking our body is at rest condition. Because you are walking on the road always some force is acting against your motion (i.e.) due to air and weight of the person. this hands move forward and backward will help for decreasing force due to air and to decrease the inertia due to weight of the body.

So option 3.
