In Sambo, an underhook is a powerful grappling position where a fighter slides one arm underneath the opponent’s arm and lifts upward to control their body. The arm usually wraps around the opponent’s side, shoulder, or upper back.
This position gives the athlete strong leverage and better body control during clinch exchanges. Because Sambo focuses heavily on throws, takedowns, and positional dominance, the underhook often becomes a key tool for setting up offense or stopping an opponent’s attack.
A strong underhook helps a Sambo athlete control posture, break balance, and create angles. For example, when you secure an underhook on one side, you can turn your opponent, pressure their upper body, and limit their movement.
This control makes it easier to attempt trips, hip throws, or body-lock takedowns. Meanwhile, it also helps defend against certain throws by disrupting the opponent’s grip and positioning. In many Sambo matches, gaining inside arm control through an underhook can quickly shift momentum.
The underhook matters because Sambo rewards effective control and explosive transitions. Fighters often battle for this position in close-range situations because it can decide who controls the exchange.
For Instance:
If a competitor gains a deep underhook and drives forward, they may move directly into a throw or force the opponent off balance. Therefore, mastering the underhook improves both offensive power and defensive stability, making it an essential part of successful Sambo technique.
