Practice setting form by setting with partners. Partner tosses ball to setter who sets to target hitter. Setter starts from behind 3 meter line. Setter must run to spot and set to target. Tosser from other side of net throws to player who passes to setter who sets to target.
Contact is quicker and softer without much follow through.
Set far enough away from net so blocker cannot intercept and high enough so attacker can contact at highest point possible. Practice each with triangle passing drill.
