Dogmatic Opinion
Online, I find DECCHI-RI and HATOMUNE—“protruding rear and pigeon chest”—mentioned as a basic posture in certain dance or martial-arts contexts.
Still, neither DECCHI-RI nor HATOMUNE sounds like the kind of description most people would be delighted to hear applied to their body, so I doubt I will have many opportunities to use the expression myself.
The adverbial meaning “a large quantity” or “looking heavy” was completely new to me when I encountered it.

For Japanese Learners
For the noun, protruding buttocks, a protruding rear, or a swaybacked/posterior-out posture may fit depending on context. The rare adverbial use requires a separate translation such as in a large amount or heavily. This is not a high-priority everyday word for learners.
