Awesome flow technique from PhuketTopTeam head MMA, Wrestling Phuket & Submission Grappling Coach Eric Uresk.
Starting from the rear waist lock, snap back the opponent to a bottom wrist ride.
Secure the chest to back & place the hook over top leg. Then using the free arm, create a post blocking the opponents free arm. Finally, secure the Kimura trap & pinch the knees for the Armbar finish.
Work gradually through the steps, watch the details & add this to your skill set.
