At the Police class we have been studying Ju Ji Gatame (side arm bar).
A nice demo by Ronda Rousey.
Funny her technical points are the same as what Ben hammers.
Look at her body position:
- Baz's thumb pointing at the ceiling
- Legs together - squeezing the arm between the legs
- See she sits up chest close then pulls the arm back with her whole body not just her arms
