About Whetstone Jiu Jitsu

Whetstone Jiu Jitsu offers Brazilian Jiu-Jitsu in Cortlandt Manor, NY, with a curriculum that emphasizes skill-building for both beginners and experienced practitioners. The academy provides structured classes in both gi and no-gi formats, focusing on technical progression through position-based instruction, detailed drilling, and live training. Beginners’ classes introduce the fundamentals of BJJ, while all-level and advanced sessions link techniques together and explore broader themes, allowing students to develop a deeper understanding of the art. The kids’ program at Whetstone is organized by age groups, starting as young as four years old. The youngest students (ages 4–6) work on physical coordination, listening skills, and teamwork as a foundation for later training. Classes for children ages 6–10 introduce core positions, takedowns, and escapes, with a mix of warmups, positional drills, and live rounds. Older kids and teens (ages 10–15) take on more advanced techniques, including submissions and refined positional work, preparing them for the demands of adult classes. Beyond Brazilian Jiu-Jitsu, Whetstone offers all-levels MMA and Muay Thai, blending striking, wrestling, and grappling for students interested in a broader martial arts education. Open mats and position-specific drilling sessions are available throughout the week, and the academy welcomes drop-ins. The facility is wheelchair accessible, and the schedule is designed to accommodate a range of ages and training goals in the Westchester and Lower Putnam area.
