Both the tricep and the bicep are muscles which control rotational movement at the elbow. The bicep contracts when the forearm is flexed, and the tricep contracts when the forearm is extended.
If the elbow is flexed, the palm of the hand can not face the floor. If the elbow is at 90 degrees that is what flexion is. If you rotate the forearm, the palm will face anteriorly. If you don't, the palm will face posteriorly. The only way to have the palm face the floor is for the forearm to be extended and the forearm pronated.
Biceps Biceps
There are three muscles involved in flexing your elbow. They connect your upper arm to your forearm. When they contract, they become shorter and pull your forearm toward your upper arm.
The muscles are moving antagonistically.

The forearm is the part of the upper limb between the elbow and the wrist. It contains two bones: the radius and ulna. The forearm is responsible for movements like flexion and extension of the wrist and fingers.
"Forearm" refers to the lower part of your arm, between your elbow and your hand.
