backtobelly

Backtobelly is a neologism formed from the words back and belly. It lacks a single, formal definition and is used in different domains to describe a transition or orientation involving the back and the abdomen.

In child development, the term is often used to describe the act of rolling from supine (lying on the back) to prone (lying on the belly), a milestone commonly referred to as rolling over. In physical therapy and rehabilitation, backtobelly movements may be used to describe therapeutic sequences that begin with the patient on their back and progress to a belly-down position, supporting torso strength and motor control.

In performing arts and sports such as gymnastics, dance, or diving, backtobelly may describe a transition in which the performer moves from a back-facing orientation to a belly-facing orientation, or from back support to a prone stance, depending on the choreography.

Spelling and hyphenation vary: backtobelly, back-to-belly, or back belly are encountered in informal writing. Because it is not a standardized term, definitions are often determined by the source rather than by an official glossary.

Given its variability, researchers or practitioners using the term should define it explicitly when publishing or instructing, noting the domain, exact orientation, and whether the movement is initiated from the back or the belly.
