Abdominal fanning

In this rigorous exercise, I first empty my lungs as much as I can and hold my breath. Then I move my abdominal muscles rapidly back and forth. The exercise strengthens my abdominal muscles and stimulates my digestive system.

I start by emptying the lungs from the top, then proceed to the middle, and lastly, the bottom. By leaning forward while placing my palms on both my kneecaps, I squeeze out part of the residual volume at the bottom of my lungs, through my mouth. My stomach moves in the same manner as when I cough to clear my throat.
