What advantage does practicing set routines offer according to the block system?

Practicing set routines within the block system primarily facilitates the development of muscle memory, making the exercises become second nature for the practitioner. When individuals engage in a consistent set of movements, their bodies learn the specific patterns and mechanics involved, leading to improved efficiency and effectiveness in execution. This process helps enhance coordination, stability, and muscle engagement during the exercises, which can contribute to better results over time.

While preventing overtraining is an important aspect of any training regimen, it does not directly stem from the advantage of practicing set routines. Spontaneous exercise selection is contrary to the idea of set routines, as consistent practice relies on predetermined exercises. Lastly, while a well-structured block system can aim to promote balanced training across different body areas, this is not the central advantage of practicing set routines. The core benefit lies in establishing familiarity and instinctive performance of the exercises through repetition.
