After sitting for a long time, which may cause pains and aches, we can change the position to the walking back and forth. After walking for a long time, we can change to the sitting posture.
This is called changing the positions; sitting, lying, standing, walking. You should allot them properly.
While you are walking back and forth, be aware of the feeling or the feet. It is not necessary to say to yourself, “right foot moves, left foot moves.”
Be aware while you are walking. If you walk without self-awareness, it is useless.
