First Things First: You should always start off in your goalie ready position, which is being on your toes, knees bent, hands out, shuffling side to side, and a few steps in front of the goal line.
As a goalie there are several ways to block a shot. Let's watch some videos that demonstrate some of these ways.
Method #1: Coming up towards the ball and scooping the ball up into your arms and chest.
Method #2: Jumping and diving at the ball when it is kicked low and hard to save it from going into the net.
Method #3: When the ball is kicked high or above your head, jump and punch the ball out over the goal so it does not fly into the net
There you go! ;)
