Age-Structured Youth Training
Kids Jiu Jitsu at Whetstone
Whetstone Jiu Jitsu offers age-structured Kids Brazilian Jiu Jitsu classes in Cortlandt Manor, New York. The three groups—ages 4–6, 6–10, and 10–15—give students instruction appropriate to their stage of development rather than placing every child into one combined program.
Younger students build familiarity with class structure, movement, following directions, and working with teammates. Older groups develop a progressively deeper understanding of Jiu Jitsu positions, takedowns, control, escapes, and age-appropriate technical work.
Families from Northern Westchester and nearby Lower Putnam County can review class times on the Schedule page or contact Whetstone for help identifying the appropriate age group.
- Jiu Jitsu ages 4–6
- Jiu Jitsu ages 6–10
- Jiu Jitsu ages 10–15
- Progressive instruction appropriate to age

Ages 4–6
Jiu Jitsu Ages 4–6
This class prepares kids to participate in Whetstone’s older Jiu Jitsu classes. The emphasis is on following instructions, working as part of a team, and developing physical skills such as balance, coordination, and athleticism.
Students become familiar with how a class is organized, how to move in the training space, and how to work safely with partners. Those habits create a foundation for continued learning without expecting young children to perform the more advanced technical work taught to older groups.
The goal is to make foundational movement and class participation understandable for this age group while helping each child become more comfortable with the routines of martial arts training.


Ages 6–10
Jiu Jitsu Ages 6–10
This group builds a foundation in the primary Jiu Jitsu positions. Students practice takedowns, positional control, and escapes while learning how the major parts of a grappling exchange fit together.
The established class structure includes a warmup, positional drill, technique instruction, and live training based on the focus of the day. Positional drilling gives students a defined situation to practice, while technique instruction explains the movement and objectives. Live training lets students work with resistance within the class focus.
Ages 10–15
Jiu Jitsu Ages 10–15
Our Ages 10–15 Jiu Jitsu class takes a deeper approach to grappling, with a greater emphasis on submission holds, wrestling positions, and live application. Students build a strong foundation in the primary Jiu Jitsu positions while learning how to connect each phase of a grappling exchange.
Classes focus on takedowns, positional control, escapes, and submissions, helping students understand not just individual techniques, but how they work together. As students develop, they learn to create opportunities, maintain control, defend effectively, and transition between positions.
This class is designed to build technical skill, confidence, discipline, and practical grappling ability in a structured and challenging environment.
