Roll the ball out

When practicing a skill it is better to roll out the ball and perform a move rather than performing it when the ball is stationary. 

The reason behind this is that in a game situation there is barely three situations where you would kick a ball when it is completely still, the rest of the time it is rolling and is moving in some way. Practicing a skill when the ball is stationary doesn't let you experience the moving ball and isn't helping that much as it is different from when it is on the move. To get good at performing it while playing in a game, it is important to practice the skill while the ball is on the move. 

That's it
