Armbar

The armbar (also called juji-gatame) is one of the most fundamental submissions in Brazilian Jiu-Jitsu. It involves isolating an opponent's arm and hyperextending the elbow joint by controlling the wrist while applying upward pressure with the hips against the back of the elbow. The armbar can be executed from virtually every position — mount, guard, side control, and even standing — making it one of the most versatile attacks in competition.

In tournament play, the armbar is legal across all age divisions and belt levels in every major organization including IBJJF, NAGA, AGF, JJWL, and Grappling Industries. It is often the first submission taught to beginners and remains one of the highest-percentage finishes at the elite level. Because it targets the elbow (a hinge joint with a clear breaking point), referees can intervene quickly when competitors fail to tap, making it relatively safe compared to rotational joint locks.

For youth competitors, the armbar is universally permitted because the mechanic is straightforward and the "tap window" — the time between discomfort and injury — is relatively long. Parents should note that while the technique is legal, coaches emphasize controlled application, and referees at youth events are trained to stop matches quickly if a child fails to tap. The armbar accounts for a significant percentage of submission victories across all youth and adult divisions on JITS.GG.
