Background: Sport is a physically demanding activity that has a positive impact on the body. Exercise, in addition to maintaining physical fitness and being useful to one's health, it may protect a person from negative things such as stress and can be utilized as a kind of leisure. However, there are still many people who do not exercise properly. It is not necessarily excellent exercise for those who have good exercise knowledge, and it is not necessarily poor exercise for people who have less exercise knowledge. Exercising also disregards a person's age; people of all ages, young and old, are allowed to participate in sports they enjoy, such as aerobic and anaerobic activities. As previously said, in addition to maintaining physical fitness and being helpful to one's health, students should exercise to relieve tension induced by lectures. However, many students are overworked and do not consider exercise to be vital because they do not have spare time to participate in sports. Students will become unfit and unable to concentrate on the lecture subject as a result of this. Purpose: This study aims to determine whether there is a correlation between knowledge and attitudes towards the habit of exercising in students of the Faculty of Medicine, Universitas Sumatera Utara. Method: The research that will be conducted is an observational analytic study with a cross-sectional study approach. The sample to be studied in this study was 260 students of the Faculty of Medicine, Universitas Sumatera Utara who met the inclusion criteria.

Results: Based on the data obtained using the chi-square method, then the results obtained were p = 0.202 and p = 0.706 (p <0.05). Conclusion: Based on these results, H<sub>0</sub> is accepted, so there is no correlation between knowledge and attitudes towards the habit of exercising in USU Medical Faculty students.
