Multiple outlets report that an expert says sit-ups are not an effective way to lose “stubborn” belly fat. The articles state that simply doing core exercises does not target fat loss in a specific body area, and that results depend on broader factors such as overall energy balance.

The reporting also highlights concerns about typical core workouts. One claim is that doing sit-ups or similar movements can be ineffective at best, and potentially risky for some people, including the possibility of back or spine injury. In these accounts, the expert points readers toward alternatives intended to improve overall conditioning and fitness rather than relying on sit-ups alone.

Both sources frame the story as guidance aimed at correcting a common misconception—belly fat can be “burned” with targeted exercises. However, the articles do not provide consistent, detailed specifics about the exact replacement routine within the excerpts provided.
