Biceps Triceps Flexion Extension?

Do biceps flex or extend?

Contracting your biceps exhibits flexion, i.e. it brings your forearm closer to your upper arm and decreasing the angle between the two. So, your biceps is described as a “flexor” muscle. The opposing muscle of a flexor is called the “extensor” muscle. Your triceps is an extensor.

When performing a bicep flexion How does the tricep relax?

Because the two muscles are located on opposite sides of the arm, the triceps must relax enough to allow the biceps to tense and contract during a curl. As it contracts, it shortens. As the triceps relaxes, it lengthens.

Are biceps and triceps antagonistic pairs?
