Sok Glap / ศอกกลับ
The reverse horizontal elbow, known as Sok Glap in Thai, is an unorthodox and deceptive elbow strike that travels in the reverse direction of a standard horizontal elbow, catching opponents off guard with its unexpected trajectory. The term "Sok Glap" translates to "return elbow" or "reverse elbow," indicating that the strike returns from the opposite direction that conventional attacks travel. While the standard horizontal elbow slashes from the outside inward across the centerline, the reverse horizontal elbow whips from the inside outward, or from a position where the arm has already crossed the body back toward the outside. This reversal of the expected striking angle is what makes it so effective in competitive Muay Thai.
The execution of the Sok Glap typically begins from a position where the striking arm has already traveled across the body, either from a missed technique, a blocked punch, or a deliberate feint. From this cross-body position, the fighter reverses direction and whips the elbow backward along a horizontal plane, making contact with the back of the elbow or the sharp point as it travels in the reverse arc. The hip rotation for this technique is the opposite of a conventional elbow; instead of rotating the hips into the strike from the rear, the fighter rotates the hips away from the target side, then snaps them back to drive the reverse elbow.
The power generation in the reverse horizontal elbow comes from a whipping, recoil-like motion. Think of it like pulling a rubber band to one side and then releasing it. The arm crosses the body, stretching the muscles of the back and posterior shoulder, and then snaps back using the stored elastic energy combined with active hip and core rotation. While the reverse elbow generally does not carry as much raw power as a fully committed conventional horizontal elbow, its deceptive angle more than compensates. Opponents rarely see it coming because it arrives from a direction they are not trained to defend against, and an elbow that lands cleanly without being anticipated will always do more damage than a powerful elbow that is partially blocked.
In Thai fighting tradition, the reverse horizontal elbow is a weapon of the sophisticated and experienced fighter. It is not typically taught as a fundamental technique but rather introduced to fighters who already have a solid command of the basic elbow arsenal. In the stadium scene in Thailand, fighters who can successfully deploy the Sok Glap are respected for their technical refinement and ring intelligence. The technique is often seen in the later rounds of fights when both fighters are in close and have established patterns that can be exploited with unexpected angles.
Common setups for the reverse horizontal elbow include throwing a cross or hook that is blocked or parried, then immediately reversing the elbow back along the same horizontal plane. Another effective setup is to deliberately swing a wide hook that misses, drawing the opponent's guard to one side, and then snapping the elbow back across on the return. The technique can also be thrown after catching a kick, using the momentum of the catch to wind up the reverse motion. In the clinch, the reverse elbow is effective when one arm is freed from a tie-up and can be whipped across as the opponent adjusts their grip.
Defending against the reverse horizontal elbow requires awareness that it exists as a possibility, which is itself a challenge since many fighters have never trained against it. A tight guard with both hands pressed to the temples will block most reverse elbow attempts, but the unusual angle can sneak through gaps in a conventional guard. Distance management remains the most reliable defense, as the reverse elbow has even shorter effective range than the standard horizontal elbow.
