Step-by-step explanation:
The statement that indicates that a plan to assist a client in developing and following an exercise program has been effective is D. "I have lost 10 pounds (4.5 kg) because I walk 2 miles (3.2 km) every day." This statement suggests that the individual has not only incorporated the suggested physical activity into their daily routine but has also seen tangible results from their efforts in terms of weight loss. It reflects a commitment to regular exercise, which is a key outcome of a successful intervention aimed at improving personal health and fitness.
It's important for individuals to find activities they enjoy, to be consistent in their physical exercises, and to set realistic expectations about the amount of exercise needed for health benefits. Avoiding excuses and holding oneself accountable, perhaps through an exercise log or an exercise partner, can also help in maintaining an exercise program effectively.
