While still in the half way of the yoga position in which I have still my legs open and in front of my body first using one arm and then the other for 15 times each first the hand faces the floor and while moving up to touch the shoulder on the same site (quite difficult if you do it with your left arm and you hade a stroke like) then in the middle of the motion upwards, more or less, the hand moves to face the ceiling (its seems easy but it is painful)
