Background and Study Aim. Students’ physical well-being is highly affected throughout the quarantine period. The effects of it towards the performance in Physical Education is examined due to the sudden shift of educational setting. More specifically, it sought to determine the impact of physical activity performed during the quarantine period based on the FITT (Frequency, Intensity, Time, Type) principle of exercise on the physical well-being of the students as well as the relationship of the two variables.
 Materials and Methods. The study was participated by 1,648 students at Cebu Normal University who, used an online survey, answered a 34-items questionnaire with dichotomous questions. Pearson Product Moment Correlation was utilized.
 Results. The study yielded 5 major results. The students' smoking habits have no impact on their engagement to physical activity when applying the FITT principle to distant learning. The students' dietary habits do not influence their engagement in physical activity related to distant learning when the FITT principle is used. When the FITT principle is utilized, students' BMI has nothing to do with their engagement in physical activity associated with distant learning. Students who engaged in physical activity spent less time engaging in these sedentary pursuits. University students were more likely to follow a normal eating routine, and aware more likely not to engage in unhealthy behaviors like smoking cigarettes, and were more active in other physical activities like doing household chores during the quarantine period.
 Conclusions. The study found out that physical well-being has a considerable negative impact on undergraduates' physical education achievement. Thus, the FITT principle has no impact on any participation in physical activities during distance learning.
