One of the first motions taught to our students, is the Cover-Parry/Strike motion. This motion will protect the user despite which technique (or hand) that the aggressor uses (or where they are targeting their strike). It is designed to (initially) cover the face/head area, but with practice is used for most any aggressive hand/arm action attempted (by the uke/aggressor). I provided (superficial) explanations of the various methods of this techniques application in previous postings (in addition to explaining how the motion is used in response to either of the aggressor's hands being utilized).
Student's are also introduced to the initial "Tuite" techniques that are taught in Oyata's Life-Protection Methodology. The first techniques are for arm grabs as well as the "pushes" that commonly occur at the beginning of a confrontation. Though seeming to be "unlikely" occurrences, it is demonstrated how these simplistic techniques have numerous "real-world" application.
Life-Protection training involves more than just learning technique applications and kata. It also includes the recognition of situations that should alert the student to trigger their defensive attitude.
