You restricted your sample to student athletes and kinesthesiology majors. There are plenty of people who work out regularly who don't fall into those categories. The student athletes are, likely, being forced to seek out tutoring to remain on an active roster. Academics is not generally their top concern, and they're being coerced to see you. They're there to check a box. I'm sure there are good people going through a kinesthesiology program, but it doesn't have the best reputation for attracting the best students.
