Profile

Yothin F.A.Group is modern Muay Khao refined to its purest form.

Where many knee fighters rely on brute strength alone, Yothin operates with structure and patience. His fights are built on balance, clinch dominance, and positional control — breaking opponents slowly rather than explosively. He does not rush finishes. He drowns resistance.

Trained under Kru Diesel at F.A.Group, Yothin deliberately modeled his career after Petchboonchu F.A.Group, following the same technical blueprint: knees first, posture always, pressure without panic.

Fighting Style

Yothin is a textbook Muay Khao specialist.

Key traits:

  • Relentless forward pressure

  • Elite clinch control and posture

  • Long knees from range and inside

  • Composure over five rounds

  • High stamina and scoring awareness

His game is built for stadium scoring. Judges reward his control, balance, and visible dominance in the clinch, particularly in rounds four and five.

Rajadamnern Stadium Era

Rajadamnern Stadium is where Yothin separated himself from the pack.

Between 2016 and 2017, he went 8–1 at the stadium, earning a #1 ranking in his division and placing him on the shortlist for Thailand Sports Writers Fighter of the Year. His later run through the Rajadamnern World Series confirmed his status as the division’s defining knee fighter.
