Standing posture, legs apart from the width of the pelvis (or a little more, depending on your comfort):
Take a good balance by slightly turning the right foot out and the left foot towards the inside (or vice versa).
While exhaling, bend your knees slightly and go down as if you are going to sit on a chair. Keep your back straight.
Return to the standing position while inhaling.
Do this sequence of movements 5 or 6 times. And for the last, stay in the chair position for a few seconds before returning to standing.
