Shanghai keeps on the move with fitness community

At 6 am on one side of a soccer field in the heart of Shanghai Jiaotong University, a group of elderly people are busy with their Chinese yo-yos, or kongzhu. Sounds of excitement echo among the group.

Meanwhile, on the other side of the field, a group of more than 25 greet one another with hugs and high-fives.

A mix of expatriates and Chinese, they prepare themselves for a dynamic workout that will alternate between a variety of movements, all to the beat of exercise music.
