Hiking in the mountains could also be regarded as physical training, which was good for the body in many ways. It was not only an aerobic exercise, but a component of strength and endurance training as well.
Hiking in the mountains could enhance the overall coordination of body; it was also good for people's joints, bones, muscles, blood circulation, metabolism, etc. Moreover, getting close to nature could also relieve the mental stress of daily life, which was very relaxing and helped to maintain psychological health.
Shuang Pang was a professional athlete, so hiking was not an exhausting activity; his daily training was much more intense than a simple mountain hike. As a coach, Dai Li's physical performance was also much better than an ordinary person's. Therefore, while ordinary people normally needed three or four hours to reach the mountain top, Dai Li and Shuang Pang only needed about two hours.
