Methods A three-stage random sampling method was used. A unified questionnaire was used to conduct a face-to-face questionnaire survey of urban residents aged 15 to 69 in the eight districts of Beijing. Results The regular exercise rate of residents in Beijing was 68.3% in 2002, which was significantly lower than that of 78.4% in 1996. The regular exercise rate of residents was the lowest in 1999 and 2000, respectively 32.9% and 33.1%. The main reason why residents do not participate in physical exercise is that they do not have time, do not like sports, and work is very tired. Conclusion There has been no significant improvement in the status of physical exercise among residents during the past few years. It is necessary to change the way of work, to promote and popularize the importance and necessity of physical exercise, and to carry out exercise interventions for different groups of people.
