My best mate, some of you would've met over the years, does Crossfit & so does his Mrs (over 24 months now). As do a lot of others in the armed forces (clearance divers etc).
He isn't the most ripped person, but the strength/fitness the guy has is just absurd, very solid individual and for his size super fit... His Mrs has a body to die for, for you astehtics people. It can't be "too" detrimental
But indeed look at it as a sport and it does make more sense no doubt.
