When Is the Wai Kru Performed?

Ayutthay, Thailand

The Wai Kru in Muay Thai is performed before every competition as a part of the prefight ritual comprising Wai Kru and Ram Muay.

  • Before engaging in the actual dance moves, fighters circle the ring counter-clockwise, offering prayers at each corner.
    • This ritual is believed to symbolically “seal” the ring and ward off negative energies, ensuring a clean and fair match.
  • Once this initial step is completed, the fighters proceed with the Wai Kru, paying their respects through a series of gestures such as kneeling, bowing, and the traditional “Wai” hand movement.

Beyond the competition environment, the Wai Kru also plays an essential role in the yearly Wai Kru ceremony, a grand event in which Muay Thai practitioners from across the globe come together to honor their teachers and the age-old traditions of the martial art.

Held in the ancient Thai city of Ayutthaya (see image above*), this ceremony allows fighters to demonstrate their gratitude and respect, further solidifying their connection to the rich history and vibrant community of Muay Thai.

Different Elements of the Wai Kru Ram Muay Explained

Again, the Wai Kru Ram Muay is a traditional prefight ritual in Muay Thai, carrying deep cultural and historical significance.


It’s comprised of two main components: the Wai Kru and the Ram Muay. Both elements serve distinct purposes, but ultimately work towards fostering respect, gratitude, and mental preparedness in fighters.

The Wai

Derived from the first part of the Wai Kru Ram Muay, the Wai is a customary act of respect and humility, incorporating the pressing of one’s palms together in a prayer-like gesture.

  • In Thai culture, it serves as a medium through which gratitude, admiration, and honor can be conveyed to other individuals and the divine alike.
  • In the context of Muay Thai, the Wai signifies a fighter’s appreciation for their teachers, coaches, training partners, and family members who contributed to their development and success.

Kru

The Kru, also known as the teacher or instructor in Muay Thai, plays a crucial role in a fighter’s journey. For example, I refer to my Muay Thai instructor as “Kru Tom”.

The Kru is responsible for imparting the vast knowledge of Muay Thai techniques, guiding the fighters through their unique set of skills, and supporting their mental and physical growth.

A great Kru combines expertise, experience, and dedication to the art of Muay Thai, ensuring they provide the best possible training and guidance for their students.

Ram Muay

Ram Muay is the elaborate boxing dance that forms the second component of the Wai Kru Ram Muay prefight ceremonial ritual.


The primary purpose of the Ram Muay is to highlight a fighter’s style, control, and overall prowess. Every Muay Thai fighter has their own unique Ram Muay, which varies in complexity, making this ritual highly personalized and symbolic.


This dance is composed of graceful and fluid movements that demonstrate a fighter’s agility, balance, and skill in the ring.

The Ram Muay:

  • let’s fighters physically warm up
  • mentally prepare
  • showcase their fluid movements, agility, and balance

The prefight dance also demonstrates a fighter’s gratitude toward their Kru, gym, and lineage, showcasing the result of their extensive training and dedication.

The History and Significance of Wai Kru in Muay Thai

The Wai Kru ceremony has evolved over time, incorporating various elements such as the Mongkhon headband and the Prajioud armband. These sacred items are believed to bring good fortune and protection to fighters, adding a mystical element to Muay Thai competitions.

One advantage of genuinely understanding and practicing the Wai Kru is that it displays a commitment to the sport and its heritage. Muay Thai is not merely about physical prowess but also encompasses mental strength, respect, and spiritual balance. Participating in the Wai Kru ceremony enriches a fighter’s experience and allows a deeper connection to the sport’s traditions and cultural significance.

Mongkhon: The Sacred Headband

The Mongkhon is a traditional headband worn by Muay Thai fighters during the Wai Kru ceremony. This sacred item is handmade and blessed by a Buddhist monk to imbue it with protective powers.

Each Mongkhon is designed uniquely, reflecting the wearer’s beliefs and individuality. The headband is believed to bring luck and safety to the fighter while warding off negative energies.

Before entering the ring, fighters are expected to adhere to specific customs related to the Mongkhon headband.

  • They must never touch the headband before the fight or allow it to touch the ground.
    • Disrespecting the Mongkhon in these ways could bring misfortune and harm to the wearer.
  • After completing the Wai Kru ritual, the fighter’s coach carefully removes the Mongkhon from the fighter’s head, signifying the end of the prefight ceremony and the beginning of the match.

Prajioud: The Emblematic Armband

This Prajioud is a braided armband, traditionally woven from a fighter’s mother’s fabric, holds deep personal significance. Different fighters and gyms may have their own unique Prajioud designs.

While not customary, my gym uses Prajioud to denote rank and experience in Muay Thai (similar to a jiu jitsu belt)

As the Prajioud is also blessed by a monk, it carries its own set of mystical powers, believed to protect fighters and grant them strength during matches.

Sarama: Traditional Thai Music

Sarama is traditional Thai music playing during the Wai Kru and often during the fights as well.

It features unique instruments like the Ta Pong or Glong-Kag (two-faced drum), Toe Pee Java (Javanese flute), and Ching (cymbals).

Side note: The presence of Sarama extends beyond the competition environment, as it can also be played during training sessions.

Kronb Khru

Another traditionaly elemen of Muay Thai (though not directly related to the Wai Kru or Ram Muay) is the Kronb Khru. It marks a student’s completion of their training and readiness to teach others.

This event represents the culmination of dedication, hard work, and mastery of Muay Thai techniques. Upon successful completion, the student receives a Monsol, or ceremonial headwear, based on their gym’s tradition, signifying their newfound status and respect within the sport.

The Kronb Khru ceremony occurs on Thursdays before noon, either at the instructor’s home or a temple. It involves several rituals, including paying homage to the student’s trainers, presenting offerings, and reciting prayers.

For aspiring Muay Thai fighters, participating in the Kronb Khru ceremony demonstrates their dedication to the sport and their readiness to compete at higher levels.

Yearly Wai Khru

As mentioned earlier the Yearly Wai Khru is an annual tradition in Muay Thai, where competitors express their gratitude and respect to their teachers and lineage.

This annual event is a testament to the strong bonds between students and instructors, and it serves as a reminder of the invaluable knowledge and expertise that have been passed down through generations.

As a side note, many foreign practitioners also attend these events, showcasing the global reach and appeal of this ancient martial art. Participating in the Yearly Wai Khru offers vital opportunities for individuals in the Muay Thai community to interact, exchange ideas, and learn from one another, further enhancing their skills and perspectives. The event stimulates growth and development within the Muay Thai world, both on a personal level and for the sport as a whole.

One advantage of attending the Yearly Wai Khru is the opportunity for self-reflection and re-evaluation of one’s progress in the sport. It is during this time that practitioners can acknowledge their achievements, set new goals, and recommit themselves to the values and ethics that underpin Muay Thai.

How To Perform The Wai Kru In Muay Thai

  • The first step in performing the Wai Kru is entering the ring with the appropriate attire, which includes a Mongkon (sacred headband), flower garlands, and other traditional garments.
  • Once properly dressed, the fighter circles the ring three times counterclockwise, sealing the ring from negative energies and spirits.
  • The fighter then kneels down at the center of the ring and bows their head towards the ground three times (offering respect and gratitude to their teachers, parents, and spiritual beliefs)
  • This act is followed by the Ram Muay which can differ from one fighter to another, often reflecting their training gym and personal background.

Wai Kru Muay Thai Movements

The Wai Kru movements in Muay Thai are specific and personal to each fighter, and are a way for them to communicate their individual style and training background.

In general, the Wai Kru consists of three main parts:

  1. the initial circling around the ring
  2. kneeling and bowing
  3. Ram Muay dance

1. The initial circling involves the fighter walking counterclockwise around the ring, with one hand on the top of their head or resting on the top rope, and the other on their hip or waist. This movement is believed to protect and seal the ring, keeping negative energies at bay.

2. The second part of the Wai Kru involves the fighter kneeling and bowing three times in the center of the ring. This act symbolizes the fighter’s deep respect and gratitude towards their parents, teachers, and religion. The kneeling and bowing are to be performed with grace, demonstrating the composure and stoicism so highly revered in Muay Thai culture.

3. Finally, the Ram Muay dance, the third part of the Wai Kru, varies greatly between fighters. It can range from simple and basic to highly elaborate and intricate, showcasing movements that communicate the fighter’s history, background, and training lineage.
