Discerning Aiki from Overt Mechanical Movement and Pain Compliance
Interesting video from Salahuddin Muhammad (Hontai Hakkei Ryu Aikijujutsu) about the difference between technique using conventional mechanical manipulation of joints and pain compliance -- as in jujutsu -- and technique that is driven by aiki, the so-called internal methods ("aiki myoden"). In this video, Salahuddin Muhammad Sensei demonstrates both ways slowly and at speed so the difference can be observed.
