About Antagonistic Muscles
- When a muscle gets shorter it has contracted and when a muscle gets longer it has relaxed.
- Most muscles come in antagonistic pairs. This means when one contracts the other must relax.

| When a muscle contracts it is called the 'agonist' and when it relaxes it is called the 'antagonist'. |
