In this weeks episode, Rolles Gracie shows us a really nice way to counter a stalled single leg takedown attempt. It can be really difficult this break the grip from your knees when your opponent is hanging on and although he may not be able to finish the takedown, it's too late to sprawl and free your leg.
The next time you get stuck in that position give this technique a try, it makes your opponent feel like he is getting something and so he helps you get into a better position.
