Training Style
Gi Jiu Jitsu
Jiu-Jitsu classes in the Gi involve practitioners wearing traditional uniforms, known as Gis, consisting of a jacket and pants. These classes emphasize grappling techniques that utilize the Gi for grips and leverage, providing a dynamic and strategic approach to self-defense and sport.
Training Style
No Gi Jiu Jitsu
No-Gi Jiu-Jitsu classes do not involve traditional uniforms, emphasizing grappling without the use of a Gi. Practitioners wear rash guards and shorts, focusing on techniques that rely on body control, speed, and agility, making it an excellent option for those seeking a more fluid and fast-paced style of Brazilian Jiu-Jitsu.
