伸展 is a verb meaning 'to stretch out,' 'to extend,' or 'to unfold.' It combines two characters: 伸 (shēn), which means 'to stretch' or 'to reach out,' and 展 (zhǎn), which means 'to unfold,' 'to spread,' or 'to extend.' Together, they emphasize a smooth, deliberate motion of lengthening or opening up the body or an object — often with intention and control. The word carries a sense of physical expansion and release, commonly used in contexts involving bodily movement, flexibility, or spatial extension.

You’ll frequently hear 伸展 in health, fitness, and wellness settings — especially in yoga, tai chi, or morning routines — where it describes controlled stretching to improve circulation and relieve tension. It can also describe non-living things unfolding or extending, like a bird’s wings or a map, though human physical action remains its most frequent usage. Unlike casual verbs like 拉 (lā, 'to pull'), 伸展 implies gentleness, fullness, and conscious effort.
