From gross to subtle and big to small, transitions link form and content into cotinuous, fluid motion. Most practitioners focus on the broad strokes of the forms they practice and pay little attention to the seemingly less significant transitions that link them together. However, transitions are precisely what carries forward any momentum and qi development, making possible more profound levels of practice and supercharging power and health benefits.
On the other hand, when not executed properly, transitions can sever the momentum you build and thereby diminish and limit training results. Therefore, the wise and dedicated student hones in on the all-important linking components as a means of generating efficiency from move to move and advancing their practice.
