The mainsite is not for the advanced; it's just dumb. They do a one-size-fits all approach that is totally random (no programming) and centers on the long chipper hero workouts which are too much for anyone, even the advanced people.
I recommend sites that actually to periodized programming with an emphasis on strength.
www.flatironscrossfit.com (my gym)
www.frontrangecrossfit.com (the gym that always kicks our ass in competions)
Also sites like
www.crossfitfootball.com (maybe a little too strength based for me, but their mission is different)
www.calalystathletics.com (oly focused, but still good).
