Final answer:
During battle rope training, the client's breathing speed should be controlled and coordinated with the movements. Synchronizing breathing with the exertion phase of the exercise helps maintain optimal oxygen intake and control of breath.
Step-by-step explanation:
When instructing the client in breathing technique during battle rope training, their breathing speed should be controlled and controlled and coordinated with the movements. It is important for the client to synchronize their breathing with the exertion phase of the exercise. For example, they can inhale during the eccentric phase (when lowering the ropes) and exhale during the concentric phase (when pulling the ropes up). This allows for better control of their breath and helps maintain optimal oxygen intake.
