Work on the ground (including rolling)
For Groundwork, the floor is honest - it doesn't pretend to be soft because it cares for you. It's feedback is just the truth, an honest reflection of your own actions.
One exercise I heard of:
- Your partner kneels with his hands up in front of him. You roll towards him and kick his hands.
Your partner stands. You roll towards him and stop. He moves away. You roll towards him again etc etc.
