What is Deltoid in BJJ?

Quick Definition

The shoulder muscle used in framing, pushing, and controlling opponents.

Full Explanation

The deltoid is the large triangular muscle covering the shoulder joint. In BJJ, deltoids are used for framing, pushing opponents away, underhooking, and controlling posture. Strong deltoids help with both offensive and defensive techniques. Deltoid injuries can occur from shoulder locks if not defended properly. Strengthening the deltoids through overhead pressing and lateral raises supports shoulder stability during grappling.
