Here are several ways to practice the power-play breakout.
One of the most important aspects of the breakout is timing. Practice and repetition are required to perfect the timing of the breakout. The simplest way to practice the power-play breakout is to have the players break the puck out without any pressure at all from the penalty-kill forecheck. This will enable the members of the power play to familiarize themselves with their positions and their roles without having to initially worry about pressure from the penalty killers.
Power-play players start on the far blue line. The coach stands at center ice with the puck. The coach dumps the puck, and the players move to their breakout positions and start the breakout.
