She's varsity in 3 sports. She doesn't need a gym class.
However, we should not necessarily assume that gym is less than worthless. Many gym classes are taught by coaches, who can be excellent mentors to young folks. More important, gym class can be a gateway into varsity sports.
Sports teams teach kids the value of self-discipline, suffering as a vehicle of self-improvement, sacrifice for a common good. All of which are Christian virtues, praised by St. Paul and St. Peter. Kids who are playing sports are less likely to go astray.
I see this youngster is going to Trinity College, not far from where I hang my hat. I wish her all happiness & success.
