Answer:
Stand straight
Raise the hand upward.
looking up the sky shake the head
Move the hand to show a big circle
Explanation:
In the warm up exercises described above, it is logical for a person to first stand erect. This is a sort of positioning for the next steps to follow. While standing erect, he can then raise his hands upwards.
This positioning will enable him to be able to look up at the sky and then whirl his hands around in motions during the exercise. Warm exercises are preparatory exercises that precede the main exercise.
