Transliteration

Translation: question mark kick

Overview

The Question Mark Kick is a deceptive head kick that begins with the trajectory of a body kick or front kick before curving upward at the last moment to strike the opponent's jaw or temple, tracing a path resembling a question mark. [1] The initial low or mid-level trajectory causes the opponent to drop their guard to defend the body, and the sudden upward redirection catches the now-exposed head. [1],[2] The question mark kick requires exceptional hip control and the ability to change the leg's trajectory mid-flight through hip rotation and knee adjustment. [2],[3]

History & Origin

The question mark kick is attributed to various martial arts origins, including karate, taekwondo, and Muay Thai, with multiple practitioners claiming to have developed or popularised it. [1] The technique gained widespread recognition in MMA through fighters like Lyoto Machida and Robert Whittaker, and it became a staple of modern kickboxing through fighters like Gokhan Saki and Israel Adesanya. [2],[3]

Effectiveness

The question mark kick (Brazilian kick) is highly effective because it disguises a head kick as a body kick or low kick, with the trajectory changing direction mid-flight. [1] The initial upward motion draws the opponent's guard low, and the leg then redirects over the top to strike the head. [1]

Lineage

The question mark kick is associated with Brazilian fighters who developed the technique in kyokushin karate and kickboxing gyms in Brazil, where it became known as the 'Brazilian kick.' [1] The name 'question mark kick' derives from the trajectory of the foot tracing the shape of a question mark. [1]

Competition Record

Lyoto Machida used the question mark kick to knock out Randy Couture at UFC 129 (2011), which is one of the most famous uses of the technique in MMA. [1] The technique has been used by numerous Brazilian fighters in UFC competition, including Vitor Belfort and Anderson Silva. [1]

Training Notes

Start the kick as if throwing a body kick — same chamber, same trajectory — then redirect the shin upward to the head at the last moment
The deception is the entire point: the opponent drops their guard to check a body kick and the shin comes over the top
The redirection happens at the hip: roll the hip over and flick the shin from body-level to head-level
The kick traces a path that looks like a question mark when viewed from the front — low to high with a curve
Popularised in MMA by fighters like Lyoto Machida and Robert Whittaker
Set it up by throwing several genuine body kicks first to condition the opponent to the body-kick pattern
The question mark kick is an advanced technique — master the standard body kick and head kick separately before combining them

Common Mistakes

!Not selling the body kick feint convincingly — if the initial trajectory does not look like a real body kick, the redirect is useless
!Redirecting too early, so the kick is clearly heading high from the start — the change must happen late
!Losing power during the redirect because the hip rotation stalls at the transition point
!Leaning too far back when redirecting upward, which reduces the force at head level
!Dropping the guard during the complex motion — the question mark kick takes longer than a standard kick, so exposure time is greater
!Using the question mark kick without ever throwing real body kicks — the opponent has no reason to drop their guard
!Attempting it without sufficient hip flexibility — the late redirect requires excellent range of motion

Frequently Asked Questions

What's the key to making a question mark kick deceptive?

You want to make your opponent think you're throwing a front kick (tee promotion) and whip it around at the last second. According to Ji Martial Arts, a common mistake is not showing the front kick enough—people whip too early. When you become more advanced, you can literally change from a tee to a question mark kick in the final moment, making it very effective.

How do I generate power in a question mark kick?

Power comes from three key elements: rotating your hips fully so they end up side-facing rather than front-facing, pivoting on the ball of your foot rather than staying flat-footed, and twisting your hips aggressively into the kick. Ji Martial Arts emphasizes that not rotating hips is one of the biggest power mistakes people make.

What's the basic setup and execution for a question mark kick?

Start in a kickboxing stance with 70% weight on your back leg. Pick your back leg up with your knee as high as possible, then throw it out deep as if you're doing a front kick. Finally, whip your hips around and kick to the head as fast as possible from point A to point B. Ji Martial Arts teaches this progression to help students understand the deceptive timing.

Why is foot position important when rotating during a question mark kick?

You cannot stay flat-footed while rotating on your heel—it's dangerous and will hurt you. Pivoting on the ball of your foot enables hip rotation, allows you to throw multiple kicks, and lets you shift and change direction effectively.
