This video is not an advertisement for specific martial arts or any other sports. It should inspire students and people who are less active and spend too much time behind their laptops to engage in physical activities. We don't need to have muscular bodies to improve our self-confidence. Do sport if it is our passion or we want to be healthier. Self-confidence must come from inside. The idea is that we should be active enough. We believe an active lifestyle can give us a better quality of life.
