unmuscular
Without physical strength
Unmuscular describes a body or physique lacking muscle development or definition—thin, slight, or soft rather than toned or powerful.
The word often appears in self-deprecating descriptions or contrasts: His unmuscular arms struggled with the heavy box.
It can also describe movement or effort that lacks physical force or athletic quality.
