Two cones about 10m apart
Receiver comes under to receive the disc.
Throw back and return to cone
Turn and come under on the other side
And so on
And so on
And so on
Keep going until you've done 10 completions. Take in turns and do 3 sets. If you've got three people you can put a passive mark on. If you've got two people practice inside break throws (forehand on the first cut in this example)
