Terms of Use

Last updated September 11, 2026. By using Martial Index you agree to these terms.

Encyclopedia, not instruction

Martial Index is a written encyclopedia and catalog of combat sports and martial arts. Entries describe positions, techniques, history, and related concepts for reference. Reading a page is not a substitute for in-person coaching, supervised drilling, or live sparring under qualified instruction.

Train with qualified coaches

Combat sports involve risk of injury. Learn and practice under qualified coaches in an appropriate facility. Do not attempt unfamiliar submissions, throws, strikes, or weapons material from text alone. Respect your partners and the rules of your gym or sport.

Tap early

When a choke, joint lock, or crushing pressure is locked in, tap early. Pride is not a good reason to wait. If you are coaching or rolling with someone less experienced, prioritize their safety over finishing for the highlight.

Accuracy and changes

We aim for clear, careful writing, but martial arts terminology varies by gym, lineage, and rule set. Entries may be incomplete, revised, or corrected over time. Martial Index does not guarantee that any description is exhaustive or competition-legal in every organization.

User-submitted techniques (later)

We may later accept user-submitted techniques, corrections, or media. If that feature launches, submissions must be original or properly licensed, safe to describe, and subject to editorial review. We may edit, reject, or remove submissions. Do not submit material that encourages illegal activity or reckless application of force outside sanctioned training.

Intellectual property

Site design, original text, and branding are owned by Martial Index unless otherwise noted. Archive photographs are credited separately (see photo credits) and remain under their stated licenses. You may link to Martial Index; you may not scrape or republish substantial entry text without permission.

Privacy

Contact capture and list use are described in the Privacy Policy.

Disclaimer of liability

To the fullest extent allowed by law, Martial Index and its operators are not liable for injuries, losses, or damages arising from reliance on site content or from training inspired by it. You assume the risks of martial arts practice.
