Chessboxing: The Ultimate in Multitasking!
I'm sure the Ancient Persians had just this in mind when they invented chess!

Chessboxers go through interchanging four-minute-rounds of chess and two-minute boxing rounds, thus "demand[ing] the most of its competitors - both mentally and physically," according to the World Chess Boxing Organization. Of course, the drawbacks of the sport are immediately obvious -- I mean, you can't stay at the top of an intelligence game when every 2 minutes your brain cells are being knocked out!
