(B) Every day to feel more energized and relaxed.

Stand upright and bow forward at the middle. Flex knees lightly, letting your arms hang limply, near to the floor.Breathe gently and strongly, and reply to a standing state by gently pushing your body up, raising your head last.Breathe gently as you respond to your initial point.Expand your muscles a little, and repeat.
