I clicked around their website for a bit and the reason they do this is for what they call "Whole Person Education".  "To be effective, you have to be well prepared - spiritually, intellectually, physically and socially." They don't seem to be trying to create bodybuilders or marathon runners.  They're just trying to get people to respect themselves and their bodies.  And while they are forcing students to purchase Fitbits, they have had a fitness requirement since they began.  And it appears that their fitness requirements are simply to try to be active and respect your body.  While Fitbits aren't really all that good at tracking or gauging fitness, it's good that they do this because unfortunately there are people in this world who need to be taught to respect themselves and their bodies.
