No-Gi Jiu Jitsu
No-Gi Jiu Jitsu consists of Jiu Jitsu grappling usually with something called a rash guard. In this style of Jiu Jitsu, you are not allowed to grip any part of the clothes.
No-Gi Jiu Jitsu is excellent for learning self-defense as well as getting in shape. Additionally, it's great if you have a knack for competition and want to compete in No-Gi Jiu Jitsu. Many techniques from No-Gi also carry over to Mixed Martial Arts.
