Best is to get used to dropping down into this position almost reflexively, but form's more important now. You'll roll onto the shoulder same side as the knee that's down. Full somersault, like a little kid, then come up on your knees again, ready to repeat. [he demonstrates, then stands]

Might take a few tries to get it right, but it becomes second nature pretty quick.
