This week's 'Amazing Race' (Sun., Nov. 20, 8PM ET on CBS) involves posing, speedos, a whole lotta body grease ... and not much else.

We've got an exclusive sneak peek at the bodybuilding challenge that'll leave you running to the gym in shame.

'It's Speedo Time,' as the episode title says, and the five remaining teams travel to Brussels, Belgium, where they're forced to get in touch with their more muscular sides for their Detour task. Judging by the photos, no one -- including host Phil Keoghan -- has a problem with that.

Take a peek at our six exclusive photos to see what kind of exhibitionist action is happening and just how much skin is being shown off.
