Hello and greetings from Austria,
I would like to share a fun way to train joint locks. At least those that do not require small and subtle movements.
Video one shows a technique drill and video two shows the corresponding pad drill. The idea is to train the individual movements of a locking-technique like strikes, so we can (ideally) execute them in full range with full power. I also noted that executing the locks with those body dynamics makes them a lot harder to resist.
(I added english subtitles for all who struggle with my mumbled german.)
Please let me know what you think.
Fun historical fact: all three techniques are described in Joachim Meyers "Gründtliche Beschreibung der Kunst des Fechtens" from 1600.
