Inspiring video shows man exercising all over the planet

This video shows fitness blogger Steve Kamb working out in what seems like every tourist destination on earth. If that sounds sort of familiar, there's a reason. Another inveterate traveler -- filmmaker Casey Neistat -- debuted a similar, Nike-sponsored clip only about a week ago, showing himself dashing through cities around the world. (It now has nearly four million views.)

To Kamb's chagrin, he released his version eight days after Neistat's: "I'm not going to lie -- I was furious," he says. But, as he notes, his trip actually took a lot more ingenuity. Instead of Nike footing the bill, Kamb covered his costs independently, with a healthy dose of "travel-hacking" (i.e. free frequent flyer miles) thrown in -- the total cost for his 35,000-mile plane trip was an incredible $418.
