"Hold on! Five seconds left!" Twenty students gathered in a circle, holding a plank in a gym in northern China's Tianjin University.
It was a course offered by the university, through which students can lose weight while earning two academic credits or additional awards such as bikes and swimming cards if they reached a weight-loss target.
"I ate a lot but seldom did exercises on campus," said Ma Wenzhuo, a sophomore student with the university. He hopes to shake the fat off and become handsome.
Ma was the first batch of 20 students, selected from 107 applicants, who joined the 21-day weight-loss course. The course was open to students with a body mass index over 26.
