An athlete recently asked me how to achieve peak conditioning and peak strength levels simultaneously. To his disappointment I noted this realistically could not be achieved. It’s not the case, however, that one entirely negates the other. In fact the correct interplay of both conditioning and strength can maximize your performance in either.
Maximizing performance in your desired objective (either strength or conditioning) doesn’t mean simply incorporating the opposite and hoping for the best. Imagine an endurance runner tossing in a bunch of strength training leading into a running event or a large out of shape powerlifter slamming out a bunch of cardio leading into a meet. In both scenarios the athlete will likely reduce their performance. CrossFit has done an excellent job at incorporating training across the strength and conditioning spectrum (or broad modal domains in CF language), but at the same time its athletes are not in “peak” shape for any specific points within those spectrums.
