Stand so that heels, back and back head lean against the wall. We can guess that back is in curved state if this position is not maintained for more than 5 min and the back or back head part from the wall.
Attach body to the wall to the best of your ability to ensure that there is no gap between the waist and the wall. The lower abdomen is forced to tilt the pelvis backwards so that the waist can be attached to the wall. The back shoulder is also not allowed to fall apart the wall.
The shoulder can be raised upwards and should be kept as low as possible. This is the right standing posture. In this position, ease the tension slowly, with a multiple respiration.
Keeping that position, fall off the wall and slowly walk forward. Slowly walking while keeping that position is the right walking.
