Benefits of Walking: Walking And Back Health
Walking Stride and Spine Rotation
One thing about walking for exercise is the relationship between the leg movement and the spine rotation.
As your leg moves forward, your spine rotates in the opposite direction naturally.
Left leg moving forward means right rotation of the spine. Right leg forward, left rotation of the spine.
Your muscles coordinate in the walking stride to give support to the lower back.
That means if someone walks for fitness without much arm swing the spine is not getting the support it needs.
This can indicate a limitation in back mobility and possible back pain or damage of some sort.
So when you walk for exercise, your arm swing is a good indicator of back health or a lack thereof.
