2 x 2 teams with 1 ball and net in between. You throw the ball via bra throwing motion over the net and then tap the center line and you join the back of the row. Player 2 catches the ball and throws it via bra throwing motion over the net again and taps the middle line etc etc.
2 corrals on midfield, 1 on each side of the net. Trainer throws ball over the net and player taps or catches ball directly. Afterwards throw the ball into the basket = 3 points or against the basket = 1 point. Bring ball to trainer and rejoin the line.
