I've been thinking a lot about posture recently. Mine is terrible. It has been for as long as I can remember; I slump when standing next to short friends, I never sit up straight in chairs and I now slump at work and when doing dishes at home because table surfaces in Japan are a good three inches lower than they are in America!
I'm thinking about trying to improve my posture–I hear it'll make me look thinner and more confident, which seems pretty awesome–but it's tough. Just sitting up straight in my office chair long enough to type this entry is putting strain on my mid and upper back.
I'm wondering what other people have done to improve their posture. Are there techniques, devices, weight training or mental tricks that helped you?
