the red cirkels are actually cones. The cones are on a disctance of 10m (=10,9yard) seperated.
player 1 starts running towards cone 2
he makes a cut around cone 2 and runs towards cone 3.
meanwhile player 2 passes the disc to player 1
player 1 brings the disc back to player 2 (HE DOESN'T PASS IT)
player 1 cuts towards cone 2
he cuts around cone 2 and runs towards cone 4
he gets the disc from player 2 at cone 4
player 1 brings the disc back to player 2. THIS IS 1 WHOLE SEQUENCE OF THE SUICIDE BUTTERFLY.
now 2 becomes the runner and 3 becomes the thrower. 1 gets on the back of the line
the sequence is the same. runner runs to cone 2...
makes a cut towards cone 3 where he gets the disc
takes it back to cone 1
runs to cone 2 again
cuts back to cone 4 and gets the disc again.
to bring it back to the first cone again.
you repeat untill everybody completed the sequence one. Then you build up by all doing the sequence 2 times in a row. After that you all do it 3 times and then you build of by doing it twice again and finishing by completing the sequence a last time.
