As a seasoned detective, I approached the crossword puzzle with a critical eye. The clue “Muscles that stretch during pregnancy” gave me a hint that I needed to look for muscles that go through a significant change during that time. I started to think, what muscles in the body change dramatically during pregnancy? As I pondered this, my eyes caught the word “stretch,” which provided me with an essential clue that the answer might be related to muscles that undergo stretching and tension. As I continued to think and analyze, I realized that abdominal muscles are one of the few groups that undergo dramatic changes and stretching during pregnancy. The answer was clear- ABS. I felt a deep sense of satisfaction as I solved the puzzle and congratulated myself on another successful outcome.
