Turns out, I don't have to be. "Most of us have posture that's compromised in some way, but it doesn't take a lot of work to correct it," says Ezriel Kornel, MD, a spinal surgeon and professor at the Cornell University School of Medicine. "Your body simply needs to be taught to experience proper posture so that that becomes the place it naturally wants to be."
Good posture, on the other hand, gives you more than just a health boost. It can actually make you more confident and successful. A recent study by the Kellogg School of Management at Northwestern University found that "posture expansiveness"essentially, standing tall with shoulders back and chest opencreates a sense of power in yourself and in how others perceive you. This may be, in part, a result of changes in biochemistry. A recent study by Amy J.C. Cuddy, PhD, a social psychologist and associate professor at the Harvard Business School, found that standing tall increases testosterone and decreases cortisol, which makes you feel more dominant.
