Muay Thai Punch

             The punch techniques in Muay Thai were originally quite limited being crosses and a long (or lazy) circular strike made with a straight (but not locked) arm and landing with the heel of the palm. Cross-fertilization with Western boxing and western martial arts mean the full range of western boxing punches are now used: lead jab, straight/cross, hook, uppercut, shovel and corkscrew punches and overhands as well as hammer fists and back fists.
As a tactic, body punching is used less in Muay Thai than most other striking martial arts to avoid exposing the attacker's head to counter strikes from knees or elbows. To utilise the range of targeting points, in keeping with the centre line theory, the fighter can use either the Western or Thai stance which allows for either long range or short range attacks to be undertaken effectively without compromising guard.
