Clinch fighting or trapping is the part of stand-up fighting where the combatants are grappling in a clinch, typically using clinch holds. Clinching the opponent can be used to eliminate the opponent's effective usage of some kicks, punches, and melee weapons. The clinch can also be used as a medium to switch from stand-up fighting to ground fighting by using takedowns, throws or sweeps. Clinch fighting is emphasized in both striking martial arts, such as Kun Khmer, Muay Thai, Lethwei, Boxing, and Sanda, as well as grappling martial arts, such as Wrestling, Judo, Sumo, Sambo and Brazilian Jiu-Jitsu.
