Training and the adaptation to training is a cumulative process. No one workout or training method that will make the difference, but the total of all the training components blended into training over the long term is what determines the ultimate training adaptation. In fact training is synergistic so that in reality the whole is greater than the sum of its parts. That is why it is so important to plan and recognize that plateaus will occur as part of the normal process of adaptation. Use the plateau as a positive not a negative. It can and should be a springboard to further adaptation.
Too often we take a microscopic approach that blows one exercise, training session or competition result of proportion with respect to the whole training program. A macro or global perspective will go a long ways toward putting each session in the context of the whole plan. It is important to never lose sight of the ultimate objective of the training, which is to prepare for the stress of competition. Play the way you train, so it is imperative to make the training demanding and related to competition.
