Does standing with your arms behind your back like this help your posture? When I do it temporarily its to straight muscles in my shoulder/neck not to "walk" and "move" and stay like this for extended periods of time.

to me it rounds the shoulders forward

where are people getting this idea it benefits posture when most people I see with their arms like this are hunched forward/leaning forward
