It's 8 a.m. at the Sigma Phi Epsilon house at the University of Missouri-Columbia: you wouldn't normally expect a bunch of frat boys to be up at this hour, never mind doing Sun Salutations with the campus yoga instructor. But morning yoga is just one of the changes at the Sig Ep house since the Missouri chapter adopted its "Balanced Man" program in 2006—just a few years after the university punished the chapter for hazing. "We're doing our best to destroy the frat boy stereotype," says Matthew Ontell, who directs the national Sigma Phi Epsilon initiative. "This is what Greek life is supposed to be about—holding men to a higher standard." If these guys are for real, I'm impressed. What about you?
