What is Bicep in BJJ?

The bicep is the muscle on the front of the upper arm responsible for elbow flexion and forearm supination. In BJJ, biceps are used in pulling movements, guillotines, rear naked chokes, and controlling grips. The bicep is also the target of the bicep slicer compression lock. While technique is more important than muscle size, adequate bicep strength supports many common BJJ techniques, especially chokes that require arm flexion.
