High-Intensity Interval Training (HIIT) has skyrocketed and become the most interesting training trend this year, providing short and effective training sessions to shape the ideal body. The World Health Organization (WHO) has recommended engaging in at least 150-300 minutes of moderate-intensity physical activity at 40-60% of the Maximal Heart Rate (MHR) or opt for 75-150 minutes of high-intensity/vigorous exercise. Physical activity at 60-85% MHR per week can maintain and improve fitness in adults. However, frequently cited challenges to engaging in physical activity are time limitation, low motivation, and non-compliance with established guidelines. This study aims to determine the effect of HIIT on physical fitness, VO2Max, and social status. The study employed a literature review, searching for articles from electronic databases, such as PubMed, ScienceDirect, ProQuest, and Google Scholar. The results showed that HIIT can improve physical fitness and have a significant and efficient positive effect on social status. In conclusion, HIIT training can potentially improve physical fitness, VO2max, and social status in adults with a sedentary lifestyle. Keywords: HIIT, Physical Fitness, VO2Max, Social Status, Sedentary Lifestyle.
