Neither of them takes the same route, and I am particularly interested in both of them. Modern fitness focuses on practicing muscles, while ordinary traditional martial arts focuses on practicing bones. Modern fitness is relatively simple, and the effect can only be said to be average for physical health. The real traditional martial arts (90% of the market is deceptive, which will damage the body and knees after practice) can be used for health preservation and self-cultivation to a great extent. Even what you see in many novels is reflected in traditional kung fu, so personally, it is better to have a reliable teacher or system for you to practice traditional martial arts than modern fitness. But if not, fitness must be safe and reliable, and you can also have lines and figures that conform to modern aesthetics, but your health is a little poor.
