In this 60-minute video app, Rory Miller makes the case that the problem is not with the locks themselves, but with our teaching methods. A principles-based approach allows relative beginners to improvise joint locks with one hour of training, something that many traditional approaches have failed to do with hundreds of hours.
This app is available for free download with sample videos, and offers a single in-app purchase to access these joint lock lessons for the lowest possible cost.
Joint locks are widely regarded as one of the most versatile physical tools-- they can move, immobilize, submit or severely injure a threat. They are also justifiably regarded as one of the more difficult of martial arts skills to implement in real life.
Joint locks are NOT primary self-defense techniques. If you are in a position that requires self-defense you are justified in and likely need a higher level of force. However, if your job requires controlling violent people with minimal injury you must be good at joint locks and you must be able to improvise them under pressure.
Rory Miller is a writer and teacher living peacefully in the Pacific Northwest, USA.
He has served for seventeen years in corrections as an officer and sergeant working maximum security, booking and mental health; leading a tactical team; and teaching subjects ranging from Defensive Tactics and Use of Force to First Aid and Crisis Communications with the Mentally Ill. For fourteen months he was an advisor to the Iraqi Corrections System. He received a BS degree in Psychology; served in the National Guard as a Combat Medic (91A/B); earned college varsities in judo and fencing, and received a mokuroku in jujutsu.
Mr. Miller is the author of several award-winning books and DVDs, including “Meditations on Violence”, “Facing Violence”, “Scaling Force”, and “Conflict Communications”.
As an experienced martial artist and veteran correction officer, Rory Miller distills what he learned from jailhouse brawls, tactical operations, and ambushes to explore the differences between martial arts and the subject martial arts were designed to deal with: Violence.
In his work, Miller introduces the myths, metaphors and expectations that most martial artists have about what they will ultimately learn in their dojo. This is then compared with the complexity of the reality of violence.
Thank you for downloading our app! We are striving to make the best possible video apps available.
