T'ai Chi Ch'uan is one of the best exercises for standing with and realigning a straight back that I have ever found. fwiw
Yes very much agree in qigong working on spinal alignment is crucial to well being and and energy flow
Movement is initiated around the lower
dan tien (center of gravity), with the torso and limbs extensions of this point. Moving from the
dan tien maximizes the power of any physical activity with less likelihood of injury. More muscles relax when movement is from the
dan tien, requiring less effort.
Qigong movement is slow and rhythmical, with the joints and tendons loose. To be completely relaxed in physical terms is to be soft in practice. Slow, rhythmical movements are one way to keep a relaxed state.
Alignment of the spine is most important, as if the head and neck are pulled upward by a string. The spine is the central pillar of balance for the entire torso and head. Stairway to Heaven is the
qigong metaphor for the spine.
however-
The truth is that most modern humans have bad posture and thus bad alignment. And it’s not just the older folks. The younger generation has bad posture too, largely because of cell phones. There’s even a condition now called “Text Neck”. You can guess what that looks like!
If qigong could only be practiced by people with perfect alignment, then none of us would qualify, myself included.
But so far through disciplined daily practice I have personnally gained much benefite and improved alignment of my spine !
Teachers who admonish against bad alignment aren’t wrong about the negative effects. Poor posture and poor alignment definitely block the flow of qi.I am sure any good chiropractor would agree.
Start where you are, and work with what you have. Whatever hand you’ve been dealt, qigong /tai chi ,alexander technique etc will significantly improve it.
