Have bad posture is a condition that can be caused by a variety of factors, such as poor sitting or standing habits, weak core muscles, and even genetics. The two crossword solutions for this term are 'STOOP' and 'HUNCH'. Stooping is when someone bends their upper body forward at the waist, while hunching is when someone rounds their shoulders and neck forward. Both of these postures can lead to back pain and other health issues if not corrected.
