Which of the following is an example of a SMART lifestyle goal?

A SMART lifestyle goal is one that is Specific, Measurable, Achievable, Relevant, and Time-bound. The goal of stretching every morning and evening for ten minutes for thirty days meets all these criteria effectively.

This goal is specific in that it precisely outlines the action (stretching) and the duration (ten minutes). It is measurable since the individual can track the frequency and duration of the stretching sessions. The goal is achievable and realistic, assuming it aligns with the individual's personal capabilities and schedule. It is relevant as it ties into broader health or fitness objectives someone may have, and it is time-bound because it specifies a duration of thirty days for completion.

In contrast, the other options lack clarity in one or more of these SMART criteria. For instance, exercising more often is vague, as it does not define what "more often" entails. Similarly, to eat healthier lacks specific guidelines on what that means or entails. Lastly, the goal of losing weight this year is time-bound but fails to specify how much weight to lose or by what means, making it less effective as a SMART goal.
