What muscle works with the biceps to make the arm flex?

The biceps brachii has two synergist muscles that assist it in flexing the forearm. Both are found on the anterior side of the arm and forearm. One of these is the brachioradialis muscle which is largely on the forearm (see the next section) and the other is the brachialis, which is largely on the upper arm.

What muscles flex the biceps?

Brachialis: The brachialis muscle lies within the distal region of the biceps brachii. Attachments: Originates from the humerus and attaches to the ulna. Action: Flexing of the arm at the elbow.

  • Muscles of both the upper arm and forearm control movement of the forearm.
  • The biceps brachii flex the forearm and work with the supinator of the forearm to rotate it so the palm faces upward.
  • The triceps brachii extend the forearm.

What happens when you flex your biceps?

When you flex a muscle to show off, you contract the main muscle (e.g. biceps) while also contracting the muscle that has the opposite effect (triceps in this example). This lets the biceps tense up and bulge while still keeping the arm from bending out of position.

Can you flex your biceps and triceps together?

Keep In Mind: you don’t necessarily have to train both biceps and triceps on the same day. But if you do, do all triceps exercises before you start biceps. Even though I’m a powerlifter, I still say: of all the things we do in the gym, arm training is possibly the most fun.

What muscles are used to extend your arm backwards?
