Final answer:
An effective ACE Certified Health Coach collaborates with clients, helps them identify health barriers, and develops personalized strategies for sustainable health improvement.
Step-by-step explanation:
An effective ACE Certified Health Coach is one that collaborates with the client to set goals and facilitate change rather than dictating or prescribing specific actions or diets. These professional coaches work by exploring strategies to design sustainable health education and disease prevention interventions. This approach helps clients to identify their own critical problems and barriers of health, and together, they develop personalized plans that will lead to improvement in the clients' overall health.
