   An increasing number of Chinese are jogging to get and stay fit. Most joggers will run alone, but some will jog with friends or even coaches.

The Beijing Olympic Forest Park is one of the most popular spots. It is packed with runners in the afternoon, usually after work, and at weekends.

Jogging after a whole day’s work can be a way to unwind. It is true for He Wenjun, whose workplace is right near the forest park. She discovered her athletic gift at the age of seven, when she began playing tennis. Then she turned to jogging, and she has persevered with it for 10 years. “I come to jog almost every day after work, whenever I have time. I think jogging is good for my health. And for me, a girl, it helps me to achieve to keep slim,” she said.

She says she prefers jogging alone, so she can focus better. She loves jogging, even during Beijing’s smoggy days. “If the smog is severe, I’ll hold off jogging for a while. But if I really want to get away from work, I’ll wear a mask, or just ignore the smog and go on jogging,” she said.

For those who are not so athletic, jogging also has its attractions.

The success helped him recover health, and he has made friends. “Jogging does not require speed, but perseverance. If you want to stick to the game, you need to take it as a task, a habit, and then eventually a hobby,” Wu said.

Jogging is beneficial to heart-lung function, and the skeletal system, but doctors say improper technique damages the joints, especially the knees and ankles. “Excessive jogging wears down the body, and harms one’s health. Poor technique harms the muscles and skeletons, and can cause secondary injuries. And, jogging in a bad environment can cause circulation problems,” said Lu Zhiyong, attending doctor, Sports Hospital, General Administration of Sports.

Dr. Lu has some tips for joggers, and those who are thinking of taking it up.

He says people should first evaluate（评估）their physical condition, to decide the amount and type of exercise, and jogging in the open air is better than running on a running machine. It is recommended that joggers jog three or four times a week, and 30 to 60 minutes each time. The best time to jog is 4p.m. — 5 p.m.
