Ryan Gosling is a Work-Out Wonder

Ryan Gosling looks crazy delicious, sweating up a storm during a 1.5 hour work-out at a gym in Los Angeles on Monday.

The Canuck cutie, who turned 28 last week, exercised on all the different work-out machines and cooled off by stretching on the mats.

Poor Rachel McAdams–look at all she’s missing out on!

Sneakers by Reebok. (Speaking of Reebok, Gossip Girl’s Leighton Meester recently shot an ad for them!)
