Playing Tai Ji Chuan and exercising muscles in the gym, as long as they are properly trained, are beneficial to health. Two different sports, the key depends on your own preferences. Tai Ji Chuan is a slow sport and needs the guidance of a master. A master here refers to a teacher who knows truth and scientific methods, not a famous teacher. Gym training can not only exercise muscles, but also improve physical fitness and all aspects of physical fitness. Also called physical fitness, it refers to the body's adaptability to sports, and scientific training is also very helpful to health.
