They contract.
Long and complicated proteins fibres in the muscles draw across each other, bunching up, contracting the muscle.
Muscles never push - to get around this, the body puts muscles into pairs, known as antagonistic pairs, so that they each pull (contract) in opposite directions. For example, around your elbow, your bicep pulls to close your arm, and your tricep (on the other side) pulls to extend your arm.
