according to Zhang Yuqing, he took 5 kilometre every morning to warm up and then came to riverside park and began to exercise. "After I warm up, I take off my vest and do 500 push ups. Then I use the arm machine to make 70 groups of exercises, grip strength and pectoralis." According to him, over the past 20 years, as long as weather conditions permit, almost every day will exercise for 4 hours.
