Step 1

C3 passes out to C1. As the ball travels, the whole block slides towards it, with the players nearest the ball moving first.

Step 2

C1 plays inside to C2. The block shifts back a few steps, keeping the same distances between the lines and across them.

Step 3

C2 switches the ball to C5. This is the long shift: every line moves across together and the far side tucks in.

Step 4

C5 plays inside to C4, and the block shifts back a few steps the other way.

Step 5

The block is in the same shape as at the start, moved across. Check the gaps between the lines before the next pass.
