Muscles are normally arranged in opposition so that as one group of muscles contract another group relaxes or lengthens. Antagonistic pairs of muscles are muscle where one move the bone in one direction and the other moves it back the other way in transmission of nerve impulses to the muscles.That means that it is impossible to fully stimulate the contraction of two antagonistic muscles at the same time. Abs and erector spinae (lower back), located in the back next to the spine, are antagonistic pair. 2  Standing from laying position we use our abs, while laying down on our back is done by our lower back muscle. 3  The lower back muscle is a small and weak muscle not very often use in our everyday life.
