Question: Why do we swing our arms when we walk!?
Most people swing their arms when they walk or run!.!.!. But why!?Www@QuestionHome@Com


Best Answer - Chosen by Asker:
Arm-swinging improves biomechanical efficiency Notice during a walk or run that your limbs are "out of phase," left leg forward and right arm backward, etc!. This way, body torque from the leg and arm swings counter each other, stabilizing the torso and head!.
To prove this, try a brisk walk or slow jog with arms tightly crossed against your chest!. Now both your hips and shoulders will rotate by an undesirable amount, wasting energy!. Or try jogging and moving your arms "in phase," right arm and left arm forward together, etc!. "This is very difficult and unnatural!. And the faster you jog, the goofier it gets!"Www@QuestionHome@Com

Walking was once remarked as a series of controlled falls!.

You put one half of your body forwards, and then you put the other half forwards!.

The arms more or less just do what they want!.Www@QuestionHome@Com

I guess because your shoulder joint isnt fixed in a place its supposed to move freely

Could just be a habit thingWww@QuestionHome@Com
