SMART Goals

SMART goals are goals written according to a set of criteria intended to make an objective clear and trackable. In health and exercise settings, SMART commonly stands for Specific, Measurable, Achievable, Relevant, and Time-bound, although alternative versions of the acronym are also used. The original 1981 formulation used Specific, Measurable, Assignable, Realistic, and Time-related .^1,2

A specific goal clearly states the intended behavior or outcome, while a measurable goal provides a way to assess progress or completion. Achievable or realistic refers to whether the goal is feasible under the relevant circumstances. Relevant connects the goal to a broader purpose or priority, and time-bound specifies a deadline or period for completion .¹

In exercise and physical-activity programs, these criteria can be used to turn a general intention into a more defined target. For example, rather than simply intending to “exercise more,” a goal can specify the activity, amount, frequency, and time period, making the intended behavior easier to monitor and evaluate .¹

SMART goals are a practical goal-formatting framework, not a complete scientific theory of motivation or behavior change. Reviews have found that the acronym is applied inconsistently and that its criteria alone do not account for factors such as goal type, motivation, task complexity, commitment, feedback, or individual circumstances. Exercise-science guidance therefore cautions against treating SMART goals as universally optimal or sufficient for effective goal setting .^1,2
