Source notes

An exercise goal can look well organised on paper and still be poorly suited to the person pursuing it. The familiar SMART checklist commonly means specific, measurable, achievable, realistic and time-bound. Examining its use in physical activity promotion, the authors drew on 147 relevant studies and found inconsistent definitions, limited guidance and important gaps between the checklist and goal-setting research. Only three empirical studies in their search directly compared SMART goals with another goal type. The concern is that a memorable checklist has become a default without strong evidence that it is the best choice.

This does not show that setting goals is ineffective or that every SMART goal fails. Goals can support physical activity, and some goals that fit the checklist may work well. The authors distinguish the checklist from a theory explaining when goals help and why. A target for someone already confident with exercise may have different effects from the same kind of target given to someone still learning how to become active.

How Does This Show Up in Real Life?

For someone beginning to walk more, reaching a fixed step count and learning ways to fit walking into the day are different tasks. The authors suggest checking a person's knowledge, ability, resources and commitment before choosing a performance target. Where those foundations are missing, a learning goal can focus on developing workable strategies first. They also describe early research on open goals that invite people to explore what they can achieve without a preset score. In one walking study, insufficiently active adults walked farther and reported greater enjoyment with an open goal than with an individual SMART goal. That is a study-specific result, not proof that open goals always win. The practical issue is whether the goal supports both participation and a manageable experience.

The critique combines conceptual arguments with varied studies rather than estimating a single pooled effect of SMART goals. Direct comparisons were few, and definitions differed. Short walking tasks cannot establish whether people remain active for months or years. The authors call for comparisons measuring activity alongside enjoyment, pressure and other experiences that may influence longer-term participation.

Use this paper to question automatic reliance on a checklist. It supports choosing goals with attention to the person and situation, while leaving the superiority of different approaches open to further testing. A goal's neat wording alone is not evidence of its effectiveness.
