Having control in the full mount position

I've always had trouble in the full mount. I would get bucked off or reversed all the time. What's I've learned today is that the key to establishing better control is to sit high and heavy while tucking your knees underneath your opponent's arms.

By doing this, you are doing a few key things.

• It's now much harder to get bucked off


• You restrict arm movement preventing attacks from the ground


• You're opponent is now very uncomfortable, which will hopefully lead to reaction/mistakes, and give you opportunities to apply a submission

I looked around online and I thought this video did the best job breaking it down.
