Muscles can contract, and they can relax. Most muscles are connected to bones, although some are not (such as the lip muscles). All the movements of the human body are caused by various patterns of contracting muscles and relaxing muscles.
Involuntary muscles are controlled by the medulla which is present in the hindbrain part , the involuntary act involve the movement of food in our oesophagus.
Curl ups are considered a dynamic exercise because they involve movement of the body, specifically the trunk and abdominal muscles, from a starting position to an end position. Dynamic exercises typically involve a range of motion and contraction of muscles to perform the movement.

voluntary muscles
The body movement carried out by skeletal muscles that requires energy is contraction. When a muscle contracts, it shortens and pulls on bones, enabling movement of the skeleton. This process requires energy in the form of adenosine triphosphate (ATP), which is generated through cellular respiration. Activities like walking, running, and lifting involve the coordinated contraction of skeletal muscles, all dependent on energy.
prime movers : muscle that initiate a particular movement synergism : muscles that have the same action of the prime mover antagonist : muscles that come into play to oppose a certain movement
It depends on the complexity of the movement. Typically, multiple muscles work together in a coordinated effort to move a body part. For example, flexing the arm at the elbow may involve the biceps, brachialis, and brachioradialis muscles working together.
