During their first semester at Coker College, students this year will take a new required sequence designed to ease the transition from high school. But it’s not your typical orientation class.
Yes, it will involve advice on how to live independently, serve the community and engage with peers of differing opinions. But a major component of Coker College 101 compels students to do something they’re probably not used to being told to do: get fit.
All freshmen this year will take a compulsory "fitness assessment", in which they will—among other things—receive their body mass index (BMI) (体质指数) score, which measures body fat; do a one-mile rim/walk; and see how many push-ups and sit-ups they can do in a few minutes. If time permits, the students may also do curl-ups, trunk lifts, and beep tests, in which they run back and forth between two cones at increasingly quick speeds.
The
