Rules and scoring primer

How a Muay Thai bout is scored and what the common rule sets allow, written so the practice studies make sense. Not a rulebook.

What this page is

This is a primer, not a rulebook. Every promotion, federation and amateur body publishes its own rules, and they differ on the details that matter most: which strikes are allowed, how long the rounds are, what protective equipment is worn and how a decision is reached. Before you enter anything, read the rules of the organisation running it with your coach. What follows is the shape most rule sets share, so that the studies in this app land in context.

The eight limbs

Muay Thai is called the art of eight limbs because it scores with fists, elbows, knees and shins. Most professional rule sets allow all eight; many amateur and youth rule sets remove elbows to the head, pad the shins or forbid strikes to the head entirely. The app's curriculum is organised the same way: hands, kicks, knees, elbows, the clinch and the defences that answer each of them. Which of those you may use on the night is a rules question, not a technique question.

The two strikes that are most often restricted are elbows and knees to the head. If your event forbids them, the upward elbow and the spinning elbow are still worth learning as mechanics, but they are not part of your game plan for that event.

Rounds

Traditional professional bouts run five rounds of three minutes with two minutes between them. Amateur and regional formats commonly run three rounds of two or three minutes with a one minute rest. The round timer on the home page has presets for three minutes, two minutes and one minute for that reason, and every session plan is built from work and rest blocks you can change to match the format you are preparing for.

How scoring works

Most rule sets score the whole fight rather than adding up rounds, and judges look for effect rather than volume. A clean kick to the body that visibly moves an opponent scores more than several punches that do not. Balance matters: a fighter who lands and stays composed scores above one who lands and stumbles, which is why the studies in this app spend so much time on the return to the guard and on the landing after a kick.

Sweeps and throws that put an opponent on the canvas while the sweeper stays standing are scored well in traditional rule sets, which is why the catch and sweep is in the curriculum. Catching a kick and dumping an opponent is not permitted everywhere, and the way it is permitted varies; the study shows the shape of the movement and says nothing about whether it is legal in your event.

The clinch

Traditional rules allow extended clinch work: knees, elbows, turns and sweeps from the tie-up, with the referee separating the fighters only when the action stalls. Many modern and international rule sets limit the clinch to a few seconds or break it as soon as no strike is thrown. That single difference changes what a fighter trains, which is why the clinch studies here are about posture and knees rather than about long exchanges.

Fouls that come up in training

Striking the back of the head, the spine or the groin, kicking a downed opponent, holding the ropes and biting are fouls under essentially every rule set. Two others catch people out in the gym: catching a kick and holding it for more than a moment before acting is often penalised, and in some rule sets a caught leg may not be swept below the knee. Train the catch with your coach's rule set in mind.

What the app does not do

The app does not score, does not judge and does not know which rule set you fight under. It shows solo movement shapes. For anything about eligibility, age categories, weight classes, equipment or medical clearance, ask the organisation and your coach. See also equipment and sizing and what this app is not.
