1. On the run, describe a complete revolution around its vertical axis, rearranging the legs. That is, first turn sideways in the direction of movement, then back, turning in the same direction with the other side and again face. All this happens without stopping, continuously and quickly enough, with constant movement in the chosen direction.
2. From a habit, the head will spin quickly, rotation must then be stopped. If possible, run this way up to 200 meters, rotating in one direction. Then run as much, spinning in the other direction.
This exercise develops the vestibular apparatus, increases dexterity. New muscle groups are involved in the work.
