The second general fault of this training is to bent down your upper body.

You should streighten up your upper body always.

"To say the Samjae of body, that Haneul is high while Tang is low is its own proper place. Saram should be comfortable between them. So, when you lower your pose along the proper places of Samjae, you should bent your knees down lifting your head high and dropping your hip(lower abdomen) low. For these, you should not lower your spirit though you lower you pose, and you should make deep breath though you keep high spirit, and you preserve your calm sight among them."(SJKY, 3-2-1)
