Those times you grimaced at someone for telling you to “sit up straight,” they may have had the right idea for multiple reasons including weight loss. Good posture means lessened neck, back, and knee pain which helps to keep you more focused on things such as your healthy lifestyle. It also promotes confidence and helps keep you limber, so you’re more able and happy to incorporate more movement daily. You can start by sitting up straight at your desk and/or while standing or walking.
