The most influential source of self-efficacy information related to exercise is indeed past exercise performance. Self-efficacy refers to an individual's belief in their ability to succeed in specific situations, particularly regarding engaging in activities such as exercise.

When individuals reflect on their previous experiences with exercise, those who have successfully completed workouts or reached fitness goals are more likely to believe they can replicate those successes in the future. This sense of accomplishment strengthens their confidence in their ability to overcome challenges and stay committed to a fitness regimen.

In essence, past exercise performance serves as a direct experience that reinforces the belief in one’s capabilities. It provides credible evidence of skill, resilience, and the ability to achieve desired outcomes, all of which are vital factors in fostering a strong sense of self-efficacy related to exercise activities.

The other sources of self-efficacy include persuasive verbal feedback, emotional state and mood, and vicarious experiences. While these can provide support and influence a person's motivation, they are generally not as powerful in establishing self-efficacy as the direct experience of having successfully exercised in the past.
