Jennifer Aniston, 56, has been photographed showing off her toned abs while working out. The images have been shared with fans, revealing her fitness routine. However, some outlets have expressed concern that her physique may be a result of overexertion, while others simply report on her fit appearance, and it's also unclear if the story is being confused with another celebrity, Salma Hayek, who has also been reported to have shown off her toned abs.
