Please people. Check your sarcasm detectors as they are malfunctioning. The whole 'bodybuilders have known this for years' thing is simply a cliche. The poster was just going for a laugh, and got you bozos instead.
Or better yet, dispense with sarcasm and humour entirely. They fill page after page with pointless, misleading banter that adds nothing of value to either the topic under solemn consideration or its posters karma score - which should be proof enough that such levity is unwanted here. This is a highly respected veneral website; a careless joke here could have far-reaching consequences.
That's what they use to say about dancing and rock n' roll. Just saying.
It's the job of the receptor to receive accordingly. Far-reaching consequences are the fault of other readers/posters and not that of the OP -- me.
Learn how to dance!
