Female Body Builders -- Flossin' On Muscle Beach

A bunch of hardbodied female bodybuilders showed that Muscle Beach is as much about buns as it is guns ... glutin' it up all over Venice Beach, Ca for a Labor Day bikini body showdown.

The ladies strutted their stuff at the 7th annual Muscle Beach Championship and bikini competition this past Monday and from the looks of these pics ... it was a really cheeky competition.
