I told you to raise your palms to the sky because of the direction of rotation of your shoulders.
The direction of rotation of the shoulder is more important than the shape of the hand.
I raise the back of my hand up, but I turn my shoulder out of the final position.^^
When you raise your arm, don't lift it sideways and lift it forward.
When the arm is lifted, it is extended from the light abdominal muscles connected to the torso, and if you lift it sideways, the sensation will be weakened.
When you put your arms down, you can just put your palms face to face.~👐👌
