Sit Up Straight: Tips for Improving Your Terrible Posture
The more time we spend sitting in front of our computers, the worse our posture gets. Modern technology is turning us into literally twisted creatures.
In addition to being detrimental to how your body functions, bad posture isn’t cute. It causes you to jut(突出) your hips forward, slump your shoulders, and even breathe inefficiently, according to Pat Davidson, a trainer with a PhD in Exercise Physiology who is the Director of Training Methodology and Continuing Education Coordinator at Peak Performance in NYC.
Davidson explained that bad posture compromises your diaphragm(隔离), the big muscle right below the ribs that helps you take deep breaths. So instead, you start using other muscles, like your shoulders, to help you breathe. It turns out that people with lousy posture don’t walk correctly, and they count on their lower back muscles to help propel themselves forward.
Here are a few quick fixes recommended for correcting your slump:
• If you sit at a desk all day, don’t perch on the edge of your chair at work trying to sit up straight. The best thing you can do is keep your hips against the back of the chair and use it for support—that’s what it’s there for.
• Get up frequently and walk around.
• If you carry a heavy shoulder bag, make sure to carry it on both your right and left shoulder, switching off as each gets tired. Even better: wear a cross-body bag so that the weight’s more evenly distributed.
• Work out your core muscles. You can try backwards jump-roping. If the rope hits you, you have the wrong posture. Hula hooping is also a good choice.
• Focus on the upper back and shoulder muscles. One of her favorite exercises is having clients stand up against a wall, with your hips touching the wall. Put a tennis ball between your shoulder blades and try to squeeze the ball. Boating is also excellent for improving posture, since it causes you to pull your shoulders up and back.
