The Lifeguard Knows About The Arms Race...
and, for all of the praise for First Lady Michelle Obama's "toned arms," I would have to say that, compared to the Williams sisters (who were playing tonight in the BNP Paribas Showdown for the Billie Jean King Cup), her arms are downright flabby.
You could take the First Lady's arm flab and tie it to two trees, thus making a flabberhammock in which she might recline.
You could render her arm flab and fuel a fleet of trucks with fat-based biodiesel.
You want toned arms? Venus and Serena Williams should be your role models. They have spectacularly toned arms; and, all you have to do to get them is play a lot of tennis.
