Explanation:
The strongest predicator of long-lasting behavioral change, particularly in a physical fitness context, is not solely the relationship between the personal trainer and the client, the client's knowledge, the personal trainer's knowledge, or the personal trainer's fitness level. The most important predisposing factor is actually self-efficacy, which is the person's belief in their own abilities to succeed in specific situations or accomplish a task. This concept relates to the Individual Differences Principle which states that personal, environmental, and behavioral factors must be assessed when planning a physical fitness training regimen. Motivation, alongside knowledge and a supportive environment, plays a crucial role in facilitating sustained behavior change.
