buikopzet

Buikopzet is a Dutch term formed from the words buik, meaning belly or abdomen, and opzet, meaning setup, arrangement, or plan. It is not a standard entry in major Dutch dictionaries, and its use is largely confined to informal or specialized contexts. The literal meaning is "the setup of the belly," but in practice the phrase is used metaphorically to refer to how the abdominal region is engaged, presented, or configured during various activities.

In fitness and health contexts, buikopzet commonly appears as a description of core engagement or bracing. Trainers may use the expression to indicate that the abdomen should be activated or drawn in as part of a technique for stabilizing the spine or improving performance in exercises such as lifting, planking, or other core-focused routines. The exact interpretation can vary between coaches or regions, and the term is not standardized in medical or sports science terminology.

Origin and usage notes: the term reflects a common Dutch practice of forming compound nouns by combining a body part with another noun to convey a practical instruction or descriptive image. Because buikopzet is informal, it tends to appear in instructional speech, online fitness content, and colloquial talk rather than in formal writing.
