Step 1
Assume the referee's position. Your partner should be on his hands and knees, and you should pick one side to "cover," with one of your hands on his elbow, and the other on his belly.
-
Step 2
When the referee starts the action, move the hand that is on your partner's elbow under his armpit, and cup his upper arm.
-
Step 3
Move the hand that started on your partner's belly to the inner part of the his thigh.
-
Step 4
Walk around your partner toward the side that you covered. This is the "spiral" in the spiral bust, which will pry his thighs apart and bend his torso. This will cause the arm that you have cupped to bend, putting your opponents wrist in reach.
-
Step 5
When your opponent's wrist is in reach, grab it and pull it down and under him. This will take away his support and force him to flatten out.
