Which muscles are use to pick up a cup of coffee?

To pick up a cup of coffee, several muscles are involved, primarily in the arm and hand. The biceps brachii and brachialis in the upper arm flex the elbow, while the muscles of the forearm, such as the flexor digitorum and thenar muscles, control the grip by flexing the fingers. Additionally, the deltoid muscle stabilizes the shoulder as you lift your arm. Core muscles also engage to maintain balance during the movement.
