Final answer:
To build rapport, a health coach should start by asking open-ended questions about the client's health goals and motivations.
Step-by-step explanation:
An ACE Certified Health Coach can begin building rapport with a client during the initial interview by starting with open-ended questions about the client's health and wellness goals, concerns, and motivations. This approach helps establish a comfortable and trusting environment, encourages dialogue, and focuses on the client rather than the coach's achievements or direction. A successful initial interview sets the stage for a collaborative relationship where the coach can support the client through the process of change in a personalized manner.
