Several outlets report that a fitness look promoted online and among celebrities—often described as “11-line” abs—is drawing criticism from fitness experts and health commentators. The physique is typically characterized by two pronounced vertical abdominal “lines” that are marketed as a sign of being lean and toned. Coverage notes that the trend is being showcased by well-known figures, including Jodie Comer and Gemma Atkinson, and is presented by some as an aspirational body ideal.

Across the reports, experts argue that such highly defined appearances can be misleading and may not reflect overall health. They caution that chasing an “unrealistic” aesthetic may lead people to pursue extreme dieting, overtraining, or unsafe practices, particularly if the goal becomes appearance rather than functional fitness. The articles also suggest that striving for very low body fat levels to achieve deep abdominal definition can carry risks for some individuals.

The reports emphasize that visible muscle definition alone does not necessarily indicate well-being, and that people should consider sustainable, health-focused approaches to training and nutrition rather than trend-driven targets.
