Sorry guys, I know most of you know flexibility as the ability to flex, but in this thread I want to have answers regarding the other, less popular type.
There are tons of exercises that will strengthen your posterior chain, I think I have these down pretty well.
Walking with good posture, straight back, eyes forward feels uncomfortable though, it feels a lot more natural to walk slightly hunched, looking down. This feels lik a typical case of being inflexible, and flexibility is a complicated matter.
Does anyone have any good exercises I can do to make it feel more natural to walk with "good" posture?
