To rotate the forearm (supination), and for flexion and extension of the elbow.
When the bicep performs flexion, a concentric contraction occurs. In this type of contraction, the muscle fibers shorten as they generate force, allowing the elbow to flex and bring the forearm closer to the upper arm. This action is primarily facilitated by the biceps brachii muscle, which contracts to lift the weight against gravity.
bicep
The calf muscles Xd
the bicep like any skeletal muscle are there for motion. they allow the bones to move without these muscles we would not be able to move. the bicep contracts (becomes shorter) and pulls the lower arm up. giving you movement remember muscles work in pairs so when the bicep contracts the tricep (the opposite muscle) relaxes. they work together to coordinate movement sufficiently
