What important requirement must be followed when performing the exercises in Preparatory Drills?

The key requirement when performing the exercises in Preparatory Drills is to ensure a slow, controlled cadence. This approach is essential as it allows for proper form and technique, which helps in maximizing the effectiveness of each movement while minimizing the risk of injury. A controlled cadence also promotes greater muscle engagement and enhances flexibility, contributing to a more thorough warm-up and readiness for more intense physical activities.

In contrast, using heavy weights is not appropriate during Preparatory Drills, as the focus should be on executing the movements correctly with body weight to prepare the body for subsequent exercises rather than straining muscles with added weight. Allowing bouncing into positions contradicts the principles of controlled movement, which could lead to instability and increase the chance of injury. Lastly, performing all movements quickly can detract from the quality of the exercise; it can lead to poor technique and insufficient warm-up of the muscles and joints. Therefore, maintaining a slow, controlled cadence is crucial for effective and safe performance during these drills.
