President Obama stays in shape with this cool fitness tracker watch...

It's no surprise that Barack Obama likes to stay in shape.

You need to stay lean and mean when you're top dog in the White House - we've watched House of Cards.

To highlight his physical endeavours, Obama has been pictured sporting a rather high-tech FitBit Surge on his wrist in an interview with the Washington Post.

The fitness tracker watch has built-in GPS, a heart-rate monitor and real-time workout data for when he's sculpting those guns in the Oval Office.

Well, he can't be out-muscled by bear-riding, open water-swimming, Judo fighting arch-nemesis Vladimir Putin, can he?
