The study emphasized the importance of promoting physical activity and integrating health and fitness courses across all campuses. Furthermore, it confirmed a significant positive correlation between physical activity readiness and enrollment in health and fitness classes, implying that individuals who are more prepared are more likely to participate. This association is not merely chance, highlighting its consistency and importance. The study found that enrollment in health and fitness courses is significantly predicted by an individual's level of physical activity readiness. Higher preparedness levels correspond to a greater likelihood of enrolling in these courses. The regression analysis also identified variables such as age, gender, past exercise behavior, and facility accessibility as factors that influence enrollment. Overall, the findings emphasize the strong relationship between physical activity readiness and enrollment in health and fitness classes. It highlights the importance of promoting readiness and providing supportive resources to encourage engagement.
