My current favourite submission (not leglock related)
Injuries have silver linings and can be a blessing in disguise. I often tell the students that being on your knees whilst passing can be tough because there are so many different off balances and attacks the guarder can do. This has been one of the stamples over the last 5 months since my knee surgery! Hope you enjoy it as much as I have been. (Yes it is a crank as well as a choke)
