Extension: The essential feature of successful submission attempts is always extension of the limb being attacked away from the torso to a degree that renders it vulnerable. The hardest people to submit are those who contract their limbs in to the torso (though by doing so they render themselves vulnerable to other methods of attack). When it’s time to lock joints or necks – extension is the ingredient you need. don’t stay extended for long in a competitive match – so once you see it – it in place. Here, Nicky Ryan latches on to an extended arm in a way that will make extraction difficult and as a result he has a number of great submission opportunities in front of him. Now it’s time to make a as to which option he will take – that of course, is up to you – we all have our favorites – but the commonality between all those choices will be prior extension of the limb – focus on that first.
