Spinning Elbow

Last updated: May 25, 2026

What is a spinning elbow?

The spinning elbow is a rotational elbow strike thrown by pivoting on the lead foot and turning the back briefly to the opponent, then driving the elbow through the target as the body whips around. The strike originates from Muay Thai, where it is known as sok klap (also transliterated as sok glap), and has long been part of the Thai striking tradition.

In mixed martial arts, the spinning elbow is classified as a high-risk, high-reward strike. The rotation generates more power than a standard elbow because it adds the mass of the entire upper body to the impact, but the brief turn exposes the back and lowers the guard, leaving openings for a counter if the strike misses or is read in advance.

Standard elbows hit hard, but a well-timed spinning elbow lands with knockout force often enough that the technique is treated as a highlight-reel moment whenever it appears. The term is often used interchangeably with “spinning back elbow,” which is the most common version of the strike.

How the spinning elbow works

Power on a spinning elbow comes from full-body rotation rather than arm strength. As the fighter pivots, the hips and core drive the spin while the elbow follows the line of the shoulder around the body’s central axis. The point of contact is the bony tip or back edge of the elbow, which concentrates the force of the rotation onto a small surface area on the opponent’s jaw or temple.

Distance is the defining constraint. The elbow is the shortest spinning attack a fighter can throw, which means it only lands inside punching range or in the clinch. From further out, the rotation either misses or arrives with the upper arm instead of the elbow itself.

There are two versions. A half spin of 180 degrees lets the fighter return to stance quickly, keeping eyes on the opponent for more of the motion. A full 360-degree spin produces a harder hit because the follow-through adds momentum. The tradeoff is that the back stays exposed for slightly longer (Evolve MMA).

Spinning elbow vs. spinning backfist

The two strikes share identical mechanics, which is why they are often confused. The difference is the part of the body that lands.

Element	Spinning elbow	Spinning backfist
Striking surface	Point or back of the elbow	Back of the hand or knuckles
Arm position	Bent, elbow leading	Extended
Effective range	Inside punching range or clinch	Mid to close punching range
Risk to thrower	Higher, closer to opponent	Lower, more distance from opponent

A fighter cannot land a spinning elbow from outside punching range because the bent arm cannot reach. A spinning backfist can. When the distance is already closed, the spinning elbow lands harder pound for pound because the force is concentrated on a smaller, denser surface.

Is the spinning elbow legal in MMA?

Yes. The spinning elbow is legal under the Unified Rules of Mixed Martial Arts, which govern the UFC and most other major MMA promotions. Elbow strikes in general are permitted, with one historical exception: the 12-6 elbow, defined as a straight vertical elbow strike traveling from 12 o’clock down to 6 o’clock.

The 12-6 elbow rule was removed from the Unified Rules in July 2024 by the Association of Boxing Commissions and Combative Sports, with the change taking effect on November 1, 2024 (CBS Sports). Spinning elbows have always been legal because the rotational motion produces an arcing rather than a vertical strike.

ONE Championship and some regional promotions operate under different rule sets, but the spinning elbow is permitted in all major MMA organisations.

Frequently Asked Questions

How many spinning elbow knockouts have there been in the UFC?

The first UFC spinning back elbow knockout came in March 2014, when Kim Dong-hyun stopped John Hathaway at the TUF China Finale. The count reached eight by June 2024, according to Sportskeeda, and the technique has appeared more frequently since, including back-to-back spinning elbow knockouts on the same main card at UFC 319 in August 2025.

What is the spinning elbow called in Muay Thai?

The Thai name is sok klap (also transliterated as sok glap). The technique has roots in the older Muay Boran style and has been part of Thai stand-up fighting for generations.

Is the spinning elbow harder to defend than a regular elbow?

Generally yes. The rotation makes the angle of attack difficult to read, and the strike often arrives from a blind side. Defending against the spin is still possible when the opponent recognises the setup early enough to step out of range or close the distance and smother the rotation.

Why do fighters risk turning their back?

The payoff is knockout power that few other single strikes can match. A correctly executed spin only takes the eyes off the opponent for a fraction of a second, while the strike that follows can end the fight outright.
