We know numerous movements in our body,but we should be aware about the muscle movement categorization.
Agonist- A muscle that causes motion.
Antagonist- A muscle that can move the joint opposite to the movement produced by the agonist.
Target- The primary muscle intended for exercise.
Synergist- A muscle that assists another muscle to accomplish a movement.
Stabilizer- A Muscle that contracts with no significance movements.
Dynamic stabilizer- A biarticular muscle that simultaneously shortens at the target joint and lengthens at the adjacent joint with no appreciable difference in length. Dynamic stabilizers occur during many compound movements.
Antagonist stabilizer- Muscle that contracts to maintain the tension potential of a biarticular muscle at the adjacent joint. The antagonist stabilizer may be contracted throughout or at only one extreme of the movement.
