A 'new' Wolf Blitzer returns to CNN

Viewers of CNN's  "The Situation Room" can look forward to a brand new host in 2010; or at least a new version of host Wolf Blitzer, according to a Tweet Blitzer sent out Wednesday morning.

"Just spent 45 minutes spinning at gym," Blitzer wrote. "A great sweat. And last night did Yoga. A new me coming back to SitRoom next Monday."

Blitzer's not joking about the sweat: One 45 minute class on a stationary spinning bike can burn 500 calories.
