I'm ready to send posture talk all day long! And I'm fascinated by this particular swap out of young v. old:
I am so glad you asked!!!
Okay, so to start with, young Obi-Wan is a good example of how you can actually have decently healthy posture without looking too uptight! (I mean he still looks uptight but that’s because he is.) His shoulders are on level plane, which bodes well for those muscles. His lower spine probably is curved, which would probably hurt over time, but if you have strong back muscles they should be supple enough to pull this off for a while. You can see that even though his hips are tilted, his pelvis is not tucked under him, so he is being primarily held stabilized by his gluteal muscles (good because they are big and strong muscles) instead of his hip flexors (bad because they are smaller, tendinous, and more prone to strain.) His abdominal muscles are being engaged by holding the relaxed weight of his stomach, instead of by sucking in and clenching the way that so many of us are taught to do but which so easily leads to back pain and a weak abdominal wall. So, hooray for padawan Obi-Wan! He has enough latent strength in his body that he can stand in his awkward, I-don’t-know-how-to-take-up-space way and probably not have a backache in the morning. In other words, this is the stance of someone who is habitually uptight and intentional about movement trying to appear more casual and spontaneous than he is.
Older Obi-Wan: oh boy. So, there is a way to stand in this pose and have a straight back/neck and to have the power of the core and lower body available to aid the arms in case of a swing. He’s not doing it. He’s too busy GUARDING HIS CHEST because this is what Obi-Wan does, constantly, all the time, obsessively. His shoulders are rolled forward, which weakens them and endangers his rotator cuff to injury, but hey, it guards his chest. He could strengthen his whole stance by letting his sternum press forward, but hey, then his sternum would be vulnerable. Psychologically speaking, it’s almost like he GUARDS HIS HEART.
You see this tendency throughout the series. You know how he’s always crossing his arms in front of himself? In my observation of body language, there are two ways that people cross their arms. One way is to take up more space and assert dominance; that usually involves shoulders pulled back to their full breadth, chest sticking out, arms resting there kind of like a threat. Then there’s the way that functions to take up less space/avoid scrutiny/hide self-perceived flaws: shoulders hunched, chest caved, hands resting there so they can fidget with hair/facial hair. Physically speaking, Obi-Wan crosses his arms in the second way. I know that I, for one, infer certain things about his character based on that. It kind of drives me nuts when people assume any character who crosses his arms is doing it in a domineering way. I’m like, but look at the forward roll of those shoulders!
Anyways, if you’re reading this, take a break and STOP trying to pull your shoulders back. This often just strains them. Instead, let your spine straighten (imagine you have a tail and it would hurt to keep it tucked under you; imagine you have lasers shooting out of your nipples and they should be aimed straight ahead of you and not at the floor or the ceiling; try whatever works) and let your shoulders HANG from the frame of your skeleton. That’s what they’re supposed to do. They should feel relaxed, not like you’re rowing a boat. Not like Obi-Wan’s shoulders feel by the end of the Revenge of the Sith.
