We don't have fall, but I start in early October and do put out some Halloween stuff with fall. After Halloween I take that stuff out and leave the fall until I put out Christmas. Like Bookmark August 14, 2008 at 2:14PM.

Antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonisic pair is the biceps and triceps; to contract - the triceps relaxes while the biceps contracts to lift the arm. Reverse motions need antagonistic pairs located in opposite sides of a joint or bone, including abductor-adductor pairs and flexor-extensor pairs.
