Beijing retiree Yang Hua was devoting a lot of his time to staying fit by completing his favorite exercises. But, according to his doctors, his routine may have done more harm than good—he recently suffered an illness because he was exercising the wrong way.

“Many people today still do not know how to exercise in scientific ways. As a result, they do not gain from the exercises and in fact may even hurt themselves, said Yang Zeyi, an executive board member of the Asian Council of Exercise and Sports Science.

Health experts said that a cardiopulmonary（心肺的） exercise test is necessary for middle-aged and senior citizens and those with special conditions. The test helps those engaging in exercise know whether their routines（惯例） are safe. It also can find potential unhealthy changes to exercisers' organs and provide suggestions to get fit by conducting real-time and continuous measurement of blood pressure and other physical parameters. The test can also analyze the maximum functioning of which the cardiopulmonary system is capable.

In the past, Yang would not think of creating an exercise plan because of his physical condition.

“I liked to do exercises in the evening but experts told me that the high-strength exercises a

t night would be harmful to my health. They advised me to choose some easy exercises such as walking and to limit the length of time I exercise,”he said. Sun Kanglin, Director of the Beijing M unicipal Bureau of Sports, said, “Exercisers should choose a proper routine and length of time to engage in the activity according to their age, physical co ndition and profession. It's im portant to give scientific directions to today's exercisers.”

He said Beijing's 18 districts and counties all have physical monitoring stations where people could get suggestions on how to exercise.

“The number of such stations will increase to more than 100 in the future and they will be able to regularly monitor citizens’ physiques. They will also publish statistics for the public,” he said.
