Experiencing visible fitness progress, such as weight loss or muscle gain, can substantially enhance psychological well-being. It boosts self-esteem and reinforces positive behaviors, creating a feedback loop that motivates continued effort. Progress stimulates the release of endorphins, leading to increased happiness and reduced stress. Conversely, the absence of progress can lead to frustration, potentially causing individuals to abandon their goals. Thus, seeing measurable improvements promotes a positive mindset and encourages persistence, emphasizing the importance of tracking one’s achievements.
