Submission moves are techniques used in grappling sports like Brazilian Jiu-Jitsu and MMA to force an opponent to concede defeat. These moves typically involve joint locks or chokeholds that apply pressure to specific body parts, making it difficult or painful for the opponent to continue. Practicing submission moves requires skill and control, as they can cause injury if applied too forcefully. Athletes often train extensively to master these techniques, ensuring they can execute them safely and effectively during competitions or sparring sessions.
