Underhook Meaning in Brazilian Jiu-Jitsu

Underhook in Brazilian Jiu-Jitsu is a control where one arm goes under opponent arm. The practitioner threads an arm beneath the opponent’s arm and reaches upward. This position gives strong control over the opponent’s upper body and posture. The underhook helps direct movement and create angles during grappling exchanges. Proper shoulder pressure increases control and limits opponent mobility. The practitioner keeps the elbow tight to prevent losing position. This grip allows transitions into takedowns, passes, or dominant positions. Opponents try to remove the underhook to regain balance and control. Constant adjustment helps maintain the advantage during movement. Training focuses on timing and positioning for effective use. The underhook works well in both standing and ground situations. Strong body positioning improves leverage and control significantly. The practitioner combines the underhook with head positioning for stability. This creates better control and reduces counterattack opportunities. During a match, a grappler secures an underhook in a clinch. The attacker controls posture and turns the opponent sideways. This creates an opening for a takedown or positional advance.
