Fourth Dimension Jiu Jitsu

Fourth Dimension Jiu Jitsu is led by head coach Zack Ghalayini, a black belt under Ryan Hall with more than 350 competitive matches shaping his approach. The academy’s curriculum is designed to meet students where they are, whether that’s a child stepping onto the mats for the first time or an experienced competitor refining their game. Caitlin Ghalayini, the women’s head coach and a No-Gi World and Pan American Champion, also plays a key role, bringing high-level competition experience to the women’s program and assisting with youth classes. The school operates as an affiliate of Fifty/50 Martial Arts, where Zack earned each belt and developed his coaching philosophy. Training at Fourth Dimension Jiu Jitsu covers both gi and no-gi Brazilian Jiu Jitsu with an emphasis on fundamentals for beginners and deeper technical work for advanced students. The youth program integrates jiu jitsu, wrestling, and judo to build a versatile grappling foundation while emphasizing discipline and athletic movement for ages 2 to 16. Adult classes focus on covering the core positions and techniques needed for most grappling exchanges, with options for those interested in more detailed study. Women’s only classes take place every Friday evening, providing a dedicated space for female practitioners at all levels. Open mat sessions are available for all adult students, allowing time for live training and positional drilling outside of structured classes. Located on Dumfries Road in Manassas, the academy draws students from the local area and nearby communities like Centreville and Haymarket. This balanced program suits families, new students, and anyone wanting to develop a solid Brazilian Jiu Jitsu base across both gi and no-gi formats before deciding where to specialize.
