How long would it take me to have really really good posture?

Question

My posture isn't bad now, but it could be better. My boyfriend is a marine now and I noticed that when he came home from boot camp that he had really good posture and I don't think he was even trying.

Answer 1

Probably not that long.

Just conciously try to notice when you're slouching, then straighten your back and shoulders.

If you keep this up, after probably a month (I'm not really sure how long...) standing/ sitting up straight will just come naturally.
