The Leg Lock Arsenal by Gokor Ambaryan

Excellent, different

Different take on leg locks but no less effective

Hip control and proper grips

His instructions are very concise. It is about how to control your opponent's hips with your feet, shins, thighs or even upper arms. Some fancy but a lot of straight forward attacks from standing to the ground and from the ground top and bottom. Highly recommend!

Highly recommended.

I think this DVD is one of the best foot lock DVDs in No Gi. Especially it's very detailed about the entries of several foot locks. Highly recommended.
