This video features the players doing warm up hitting lines with Anjinho Bacil during the beach practice. The players are getting more physically ready for the tougher more intensive drills that include more attacking.
 
What I like about this video is it brings up the important point that the passer / hitter should always pass the ball infront of the setter in beach. On a tough serve / free ball / even warm ups the passer needs to work to get the ball in front of the setter to set up the offense.
