A realistic approach to setting fitness goals involves establishing specific, measurable, achievable, relevant, and time-bound (SMART) objectives. Begin by assessing current fitness levels and identifying areas for improvement. Set small, attainable milestones that can be progressively built upon, allowing for gradual growth and avoiding overwhelming challenges. Remain flexible, adjusting goals as needed based on personal circumstances or progress. Emphasizing consistency over perfection fosters a healthier mindset towards fitness; celebrate achievements, no matter how small, to maintain motivation over the long term.
