What muscle is the antagonist in the dumbbell curl?

What is the antagonist in a dumbell curl?

When you do a dumbbell curl, your triceps are the antagonists, for example.

What is an example of an antagonist muscle?

The most common example of antagonistic muscles are the biceps and the triceps. As the agonist muscle contracts, the antagonist relaxes, helping to manage and regulate the movement of the former.

What are the bicep muscles?

The biceps is a large muscle situated on the front of the upper arm between the shoulder and the elbow. Also known by the Latin name biceps brachii (meaning “two-headed muscle of the arm”), the muscle’s primary function is to flex the elbow and rotate the forearm.
