Learn to Improvise Joint Locks Under Pressure with Rory Miller. Same videos as the Joint Locks DVD for much less! Video Chapters: • Intro • Principles • Hinge Joints • Ball and Socket Joints • Gliding Joints • Fingers • Principles Review • Lock Flow Drill • Escaping Locks • Conclusion 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.

Welcome to CombatMMA - Your source for cutting edge training and interactive martial arts training apps. - 48 HD quality AirPlay®-enabled videos - Demonstration and high quality instruction - Text/graphical overlay for an enhanced visual experience - Slow motion and contact applications of each flow - watch the video on your TV with AirPlay®. - No Internet connection is required Combat Flows offers you an opportunity to train several different combative flows moving from kickboxing to trapping (clinch range) to ground fighting. The idea of flow is key in martial arts combat - to be able to transition from one range of combat to another, or one art to another and demands a higher sense of awareness and developed attributes. The techniques in these videos, therefore, are not intended for the beginner martial artist. They are geared towards those that have a background in Jeet Kune Do, or those that have some proficiency in all range combat. These are not just sport MMA techniques. There are 16 combative flows in this app that incorporate concepts from Bruce Lee's Jeet Kune Do. These include arts from: Savate, Muay Thai, Wing Chun, Shoot Wrestling, BJJ, Catch Wrestling, Filipino Arts, and more. We have also incorporated into this app a thumbnail video gallery to preview each combative flow at the same time. Just click on the video you want to see! Peter Chassikos is a Jeet Kune Do instructor that has over 25 years experience in the martial arts, training JKD and other arts since the late 1980s. He is an instructor in Jeet Kune Do, a certified black belt in Jiu-Jitsu and a 3rd degree back belt in Kickboxing. Peter has been featured in Black Belt Magazine (North America) and Combat Magazine (UK). He has conducted seminars in North America and in Europe. Peter Chassikos heads Toronto JKD and has developed his own style of training and fighting that stems from Bruce Lee's original teachings of JKD. It's true combative mixed martial arts... It's CombatMMA!
