There is no denying that the chart depicts the ways residents in a certain city choose to do exercise, which attracts our eyes. The chart represents that the residents show totally different inclinations towards the way to do exercise. On the basis of the above chart, the percentage of exercising alone is the highest among all the parts, at about 54.3%. An analysis concerning this trend should be conducted deeply.What accounts for the phenomenon? As far as I’m concerned, there are mainly two reasons for that. It is partly because exercising alone makes it easy for people to arrange their exercise time according to their own schedules. Another factor may be that people could choose the forms of exercise that they prefer without negotiating with others when exercising alone.According to the analysis above, it is obvious that the trend reflected by the chart will sustain for some time in the future. It is high time that people raised their awareness in this aspect.
