Presentation
This posture combines power and lightness.
Starting point
Lying down on one side, one hand in line with the shoulder is used as support. The legs are slightly bent and the feet are touching one another. The free hand rests on the thigh. The eyelids are open and the eyes fix a real or virtual point. The breathing is peaceful.

Then, during an exhalation, raise the pelvis and straighten the body while resting on the supporting hand and on the lateral side of the foot only. The body must be straight. In this position breathe several times.

During an exhalation, take the foot with the hand.

And stretch the leg upward up aiming at the vertical while maintaining the gaze.

Hold the position as long as possible while focusing on breathing correctly. If possible emphasize the full retention and extend the exhalation. Focus on maintaining the body straight as a rod.
Finally, during an exhalation come back to the initial position, close the eyelids and allow the body to come back to normal before doing the other side.
