Action Straightens the elbow, moving the forearm away from the upper arm
Other names Triceps brachii
Notes The triceps is a horseshoe-shaped, three-headed muscle at the back of the arm. It is involved in all pushing movements such as chest and shoulder presses, as well as triceps-specific exercises.

The triceps typically accounts for 60% of upper arm mass, but is often neglected in favor of the biceps.
