Learn the whizzer in wrestling: overhook, sprawl and hip work against single and double leg attacks. With UWW rules, injury figures and clear milestones.
The honest answer: the whizzer is an overhook: your arm lies from the outside over your attacker's arm and lifts their upper body while you let your hips sink back. It is the classic answer to single leg and underhook, but it works only together with the sprawl.
UWW rules reward good defense: whoever places an attacker in a danger position during the execution of a hold from standing scores 2 points [1]. However, that counts only if you yourself bring the opponent to the ground and continue the action continuously [1]. An overhook alone is not yet a point, but the start of a counteraction.
And there is a price: defense is the dangerous side of the takedown. In an evaluation of catastrophic wrestling injuries the defensive position during the takedown was involved in 74 % of cases [3]. So you learn the whizzer in a controlled way and with a coach.
You see the level change, feel the grip on the leg and go into the sprawl immediately. Milestone: you sprawl 5 times in a row in time against a partner who attacks in slow motion. Whoever reacts too late tries the whizzer against a partner who is already hanging on the leg.
Your arm swings over their arm from outside, the hand grips under their armpit or at the upper body. The elbow stays high. That is the overhook. Imagine hooking a hook over a branch to pull yourself up. Twisting arms by more than 90 degrees, locks on the forearm and holding by the singlet are prohibited [1]. Your whizzer is a grip on the body, not a lock.
You sprawl: hips back and low, your chest lies over their shoulders. The overhook turns the sprawl into a lever because you push their upper body up while your hips go down. Milestone: you hold the sprawl with overhook for 10 seconds against light resistance.
With the overhook you lift their shoulder and circle away sideways. Your angle frees their hands from the leg. Your attacker will often try to free themselves with a change of position. So stay in contact, keep breathing calmly and do not give way just because the shoulder burns: burning is a signal to release, not to hold on.
You release the position in a controlled way as soon as they let go of the leg, and return to stance or go to a counterattack.
If the overhook does not work, plan B is the reset: hips further back, hands off, step out of the grip and get back into stance. A lost whizzer costs you a moment. A twisted shoulder costs you weeks. That is practical experience, not a study.
Practice in three stages: cooperative, light resistance, then live. Move on only once you manage the first stage cleanly 3 times.
In the whizzer you work in defense, and that is exactly where the severe injuries happen. In the study of catastrophic injuries 27 of 35 cases were cervical fractures or major ligament injuries [3]. Among teenagers the share of injuries in the takedown position was 68 % in a season study [2]. Shoulder and elbow together make up 21.2 % of all wrestling injuries, with rotator cuff and acromioclavicular joint as common sites [4].
For you that means: release the whizzer at once when your shoulder twinges, never practice at full force, and do no throws from defense until you have learned them with a coach. This does not replace supervised training: learn the whizzer with a coach.
The whizzer does not win at the arm but at the head. If your head lies beside your opponent's head, they cannot rise. Your head holds the space your arm creates.
An overhook in which your arm lies over the attacker's arm to lift their upper body and weaken their leg grip. It works only together with the sprawl.
Against single leg, double leg and underhook, as soon as your opponent goes into the level change and you sprawl. The whizzer is part of the defense, not a single grip.
It loads it if you work against a pull with strength. Shoulder injuries are common in wrestling [4]. With a warm-up, dosing and a coach the risk stays manageable.
Yes, as an overhook in hand fighting against underhooks. The leg attack it otherwise defends does not exist in Greco-Roman style [1].
