A month-and-a-half ago, Amazon.com (AMZN - Get Report) CEO Jeff Bezos blew up the internet when he was photographed at the posh Allen and Company media confab looking absolutely jacked in a short sleeve shirt and vest. But now it looks like there may be a new contender for the title of swolest tech executive.

Uber's new CEO Dara Khosrowshahi has been showing up in photos looking quite buff, including in this New York Times story. The 48-year-old Khosrowshahi, who formerly headed up online travel company Expedia (EXPE - Get Report) , is apparently a fan of Peloton, the internet-connected indoor cycling bike, and was the captain of his high school soccer team, according to this profile from Reuters. But as for how Khosrowshahi got his current guns, Uber didn't respond to a request for comment about their new leader's exercise regimen.

The active Khosrowshahi is a frequent attendee at the Allen and Co. conference in Sun Valley.

Similarly, it's unclear what's caused Bezos muscles to bulge recently.

About the only things that seem to be known about Bezos' health habits are that he insists on getting at least eight hours of sleep a night.

Facebook Inc. (FB - Get Report) CEO Mark Zuckerberg, who works out at least three times a week, may want to take note of Bezos and Khosrowshahi's larger profiles of late. Perhaps he should be spending some of his two-month paternity leave doing some curls.
