15. Question: Explain how muscle movement occurs during the bicep curl?
Muscles can only pull, they cannot push. They work in pairs to create movement, where one contracts while the other relaxes and lengthens.
The hinge joint at the elbow starts in an extended position for the bicep curl. The agonist muscle is the bicep brachii, also known as the prime mover, contracts (shortens) to create the movement of flexion. The antagonist muscle, the tricep brachii, relaxes (lengthens) to allow movement to occur.
