Setting SMART (Specific, Measurable, Achievable, Relevant, Time-bound) goals in fitness helps create a clear roadmap towards achieving specific outcomes, enhancing motivation and accountability. These goals provide a structured approach that makes it easier to track progress and make adjustments along the way. Studies have shown that people who set SMART goals are more likely to achieve higher levels of success in their fitness journeys because these goals help to maintain focus and direct effort effectively. For example, a study in the Journal of Clinical Psychology found that participants who set specific and challenging goals were 90% more likely to achieve them.
