Fitness? Judging from the current trend of sports, it can be divided into equipment fitness and street unarmed fitness. Either way, the principle of fitness is, step by step, all year round. Fitness is nothing but a kind of persistence. After persistence, it becomes a habit. After getting used to it, it becomes an attitude towards life. Fitness can improve people's perseverance and make people energetic. I like a saying circulating in the fitness circle that "fitness is simply doing complex movements, repeating simple movements and persisting in repetitive movements", which is not only applicable to fitness. Well, veterans always say, I'm glad it's not too late to start and choose to start.
