Netball Drill Demonstration
The attackers need to sprint and change direction. 6 players stand Indian file. The player with the ball faces the line.
The first player leads in one direction, 2nd player immediately runs in the opposite direction. One player receives the ball with the other one doubling back to receive the next pass.
After both runners have received the ball they should pass back to the thrower. Repeat with two new attackers.
Progression: You can add a defender at the front of the line who can mark either attacker.
The thrower should pass to the free attacker.
You could also add a condition that the attackers must make 4 passers between them (inside the area) before they can pass back to the feeder.
