I had a yoga student many years ago who took a new job working as flight staff for Singapore

Airlines. She had kind of the typical schedule four days on three days off, something like that.

So she would come to class irregularly when she was in town and it was pretty dramatic to see her

posture transformation. This is not at all what happens to everybody, but it happened to her.

She developed a pretty pronounced hunchback, a kyphotic curve. It was coupled with some positive. She

gained quite a bit of upper body strength that she really got excited about doing handstands

and arm balances. But she very quickly lost her ability to retract her shoulder blades to

And it was pretty dramatic. She was able to work through it and correct it and she had to get

and our posture throughout the day, how we can reorganize our body pretty quickly. One other example,

I had a student, another student slash friend who started working on a construction site. He was

in a supervisor managerial role, but for some reason everyone had to wear boots. So like steel

toad, healed boots and there was pretty substantial heels, probably two inches off the ground.

And he developed an anterior pelvic tilt, which basically looks like from the side, you're sticking

your butt out, kind of a sway back. And again, by the time he started coming to class, he had

been working this job for over a year. And so again, his body had reorganized. What happened

structured. Now, how did that play out? Was his body all broken? Was he in pain? No. But he couldn't

squat with his heels on the ground and he used to be able to. He had lifted quite a bit prior to

taking that job. Well, I should say in an earlier life. And again, these are just two examples of how
