What is an underhook?

An underhook places an arm beneath the opponent’s arm to win inside position. See where USA Wrestling lists it and why a tie-up is not a score.
Quick answer
An underhook is an arm placed under the opponent’s arm to gain inside position during a tie-up. USA Wrestling’s curriculum lists an underhook as a head-position topic in Folkstyle Level 3 and a single underhook as a Greco-Roman set-up and control tie. It is not a scoring action. A takedown, escape or reversal is awarded only for the control the rules book describes. Treat the underhook as positioning that can lead to a score, not as a score by itself.
Where does an underhook sit among standing ties?
Standing wrestlers spend much of the neutral position fighting for hand and arm placement. An underhook is the arm that goes beneath the opponent’s arm, which usually places that arm closer to the opponent’s torso than the opponent would like. A glossary maintained for wrestling statistics describes it as having your arm under the opponent’s arm in a tie-up and calls it an advantageous inside position.
| Tie | Where the arm or hand goes | Related page |
|---|---|---|
| Underhook | Beneath the opponent’s arm | This page |
| Overhook or whizzer | Over the opponent’s arm | Whizzer |
| Collar tie | On the back of the neck or head | Collar tie |
| Wrist tie | On the opponent’s wrist | Hand fighting |
The table is a vocabulary aid. It does not rank the ties, because the best one depends on stance, angle, the style being wrestled and what the opponent does next.
What does USA Wrestling’s curriculum actually list?
The Folkstyle Level 3 outline includes “Underhook (head position)” under neutral position. The Greco-Roman Level 2 outline includes “Single Underhook” among its set-ups and control ties, and uses the phrases “Pummel to single underhook” and “Defending single underhooks.” Those entries show that the term is taught in more than one style and at more than one level.
An outline entry is a topic heading. It confirms that coaches use the name; it does not tell a parent how a drill is run or how hard it should be. Ask the club coach which level and style the practice follows before copying a video.
Does an underhook score points?
No. The NCAA rules book awards a takedown when, from the neutral position, a competitor gains control of the opponent by taking them down to the mat in bounds and beyond reaction time. An underhook can help build that control, but a wrestler can hold the inside arm for a long time without taking anyone down.
| What you see | What the official asks |
|---|---|
| Inside arm secured | Has control of the opponent changed yet? |
| Opponent driven backward | Is anyone on the mat in bounds? |
| Shoulder exposed in a scramble | Is a neutral danger call needed? |
| Both wrestlers stay on their feet | Nothing is scored; wrestling continues |
A coach scoring a practice video should write down the awarded action, then note the underhook separately as the position that helped create it.
Why does the same arm position get used differently by style?
Folkstyle, freestyle and Greco-Roman are governed by different rule sets, and the sport’s international style is governed by the UWW rules while school and college folkstyle follows NFHS and NCAA rules. The arm position can be common to all of them while the attacks that follow it, and the penalties for misusing it, are not.
If your athlete moves between styles at a spring tournament, read the rule set for the event instead of assuming a school-season habit transfers. A hold that is routine in one style can be restricted in another.
How should a coach or parent review an underhook sequence?
- Name the starting tie before naming the finish.
- Identify who gained the inside arm and whether the feet moved with it.
- Record the official award, if any, using the match record.
- Add one observation about balance or angle, not a verdict on the athlete.
Smart Wrestler’s live scoring records the scored action and its time. It does not label the tie that preceded it, so the underhook note belongs in the coach’s review, not in the official result.
Frequently asked questions
Is an underhook the same as a whizzer?
No. An underhook goes beneath the opponent’s arm; a whizzer is an overhook that goes over it.
Does winning the underhook mean winning the exchange?
No. The rules score control and position changes, not the tie that came before them.
Which USA Wrestling levels list the underhook?
The outline lists it in Folkstyle Level 3 and, as a single underhook, in Greco-Roman Level 2.
Can a beginner learn it from video alone?
A coach should introduce it first, because partner position and pressure are hard to judge from a clip.
