Which option illustrates a SMART goal for healthy habit change?

• A. Randomly start exercising without a plan.
• B. Walk irregularly when convenient.
• C. Aims to exercise more.
• D. Specific, Measurable, Achievable, Relevant, Time-bound; e.g., walk 30 minutes after dinner three times per week for 4 weeks.

Answer: (D)

The main idea here is using SMART criteria to turn a healthy-habit goal into something clear, trackable, and doable. The best choice spells out Specific, Measurable, Achievable, Relevant, and Time-bound, and it gives a concrete plan: walk 30 minutes after dinner three times per week for 4 weeks. That level of detail shows exactly what to do, how often, and for how long, with a defined end point, making it easy to monitor progress and stay accountable. The other options miss key SMART components. Starting to exercise without a plan is vague about what, when, or how often. Walking irregularly when convenient lacks regular commitment. Simply aiming to exercise more doesn’t specify the action, the amount, or a deadline.
