All muscles.
The muscle that produces a movement is called the "agonist," while the muscle that produces the opposite movement is known as the "antagonist." For example, during elbow flexion, the biceps brachii acts as the agonist, while the triceps brachii serves as the antagonist. This relationship allows for coordinated movement and control in the body.
Muscle movements happen from contraction and relaxation of the muscle cells. The movement is similar to a rubber band, however relaxation makes the muscles longer.
By tensing.

This is smooth muscle. It produces a wave of movement.
Shivering is the rapid contraction and relaxation of muscles to generate heat.
Both muscle relaxation and muscle contraction require ATP.
A muscle changes length through the processes of contraction and relaxation. During contraction, muscle fibers shorten, generating force and causing movement. Conversely, during relaxation, the muscle fibers lengthen back to their original state, allowing for the return to a resting position. This dynamic ability to change length is essential for various physical activities and functions.
Muscle movement produces heat which will increase your body temperature.
The first component involves reaching a state of deep relaxation through breathing and muscle relaxation techniques.
muscle relaxation can help you!
Antagonistic muscle pairs. That means to work in opposition to each other.One muscle produces movement in one direction and the other muscle produces movement in the opposite direction. It would seem to be contradictory but a very smooth movement occurs when they work this way.
