Fixing your spine

An article provided information on the effects on people's spines from sitting too much when they work from home. 

Main question: "...why is it so hard to sit up straight and so easy to slouch?"

Key points:

• "Posture generally refers to how you hold your body. Good posture, sometimes called 'neutral spine,' is thought to be the optimal position that puts the least amount of stress on your body as you stand, sit, or sleep."
• "...periods of slouching can weaken those muscles [core muscles around abdomen, pelvis, back that facilitate good posture], and wrongly strengthen others, making it much harder to stand tall."
• “Your body and your muscles are like clay: whatever position you hold them in, they will mold into.”
• "It takes one to two months of being hyperconscious of posture to change your subconscious posture."

One of the hallmarks of Nordic walking is the requirement for good posture (neutral spine) because you have stand tall to walk with purpose.
