When should a client take more rest between sets?

A client should take more rest between sets after a tiring set and during complex exercises because these situations demand greater recovery to maintain optimal performance and prevent injury. High-intensity exercises place significant demands on the nervous system and muscular systems; longer rest periods allow for recovery of energy systems (like ATP and phosphocreatine). Additionally, complex exercises, which often involve multiple muscle groups and joints, require adequate rest to ensure proper form and alignment in subsequent sets. This is crucial to minimize the risk of injury caused by fatigue compromising performance.

While it is certainly important for a client to listen to their body and rest when feeling fatigued, scheduled, strategic rest after tiring sets and complex exercises is essential for ensuring safety and effectiveness in the training process. Similarly, although high-intensity training necessitates rest, the correct approach in this context emphasizes the need for rest based on the overall scheme of the workout involving complexity and fatigue. Therefore, option B emphasizes a broader context of training strategies that support both performance and safety in the long term.
