When I was a kid I used to dream about settling all of my conflicts Bruce Lee-style by knocking fools out with backfists and spinning roundhouses.

Now, there’s a pretty good chance that the video above is fake, considering the kick doesn’t seem to connect, but if it isn’t it’s one of the best incidences of poetic justice we’ve ever seen.

Typically you don’t many instances that demonstrate the effectiveness of Taekwondo in combat sports.

Sure, guys like Anthony Pettis and David Loiseau (back in the day) have shown just how flashy and exciting the art can be, but as far as knockouts go, Muay Thai has become the weapon of choice for most fighters who want to finish opponents like Anderson Silva did Rich Franklin.

This kickboxing competition video out of Japan flipped that theory on its head in a matter of seconds when the Taekwondo dude immediately ran out to the center of the ring and spin-kicked the muay thai stylist into dreamland.

The Brazilian kick, AKA crescent kick, AKA question mark kick is an effective move that could net positive results against an opponent who doesn’t close the distance and who pays close attention to your hip movement in an MMA or kickboxing bout. Adding it to your arsenal offers another option when an opponent is reluctant to engage or is tired or hurt and is dropping his (or her if you’re Brett Rogers) hands in the later rounds of a bout.

Guys like Lyoto Machida and Georges St-Pierre have incorporated the unexpected move into their stand-up bag of tricks

Here’s how to do it:

First, fake a front roundhouse kick by throwing your hip around with your shin drawn back. As your opponent reacts to the movement and braces for a leg or body kick, twist your hip and snap your shin up mid-movement so that it is now moving in the direction of your opponent’s unprotected head while snapping your lower leg back, pointing your heel towards your opponent. These moves must be performed in unison and will take a great deal of practice to put all of the movements together. Flexibility is key, so stretching will help prepare you for the move.
