The word which when applied to describe the posture of the speaker in "The Fence" is "inertia."
"The Fence" is a poem about a speaker who is sitting on a fence, unable to make a decision about which direction to take in life. The speaker is stuck in a state of indecision and unable to move forward, which is a classic example of inertia.
In physics, inertia is the tendency of an object to resist any change in its motion or state of rest. In this context, the speaker's posture can be seen as being in a state of rest, unable to take any action or make a decision.
