Exhibit poor posture is a term used to describe the physical position of someone who is not standing or sitting in an upright, proper manner. This can be demonstrated by two words found in a crossword puzzle: STOOP (5 letters) and SLOUCH (6 letters). A person who is stooping has their head and shoulders bent forward, while a person who is slouching has their back curved and their shoulders slumped. Both of these postures are considered to be poor posture and can lead to health issues such as back pain and poor circulation.
