Stretch 2
1: Bend the left leg to lower the waist
2: Extend your right leg and turn your knees and toes towards the ceiling (please be conscious of your left leg's knee facing outward)
3: Take your hand and shake your body to extend the base of your right leg
(People who do not feel so painful here will have an effect even if you repeatedly move the ass to the floor and lift it up as it is)
4: While holding the hand, lift the butt, move the center of gravity to the right leg
5: Bend the right leg to lower your waist
6: Extend the left leg and turn the knee and toe of the left leg towards the ceiling (be conscious of the right leg's knee facing outward)
7: Take your hand and shake your body to extend the base of your left foot
Even if you raise the heel of the person who is bending when it is tough, it is OK.
In the second half of the video, the body is originally soft, but also introduces a stretching method for those who want to be more soft.
