Scarlett Johansson admits to a pretty strenuous workout routine to get in shape for Iron Man 2. Scarlett plays the Lycra-catsuit wearing Black Widow in the sequel and worked out pretty hard to get in shape. While the actress already boasted a body of comic book proportions even she stressed a little about being so scantily clad on the big screen.

Johansson told Extra (via omg! yahoo) while at the Comic-Con in San Diego:

“It was many, many, hours, days, and months of stunt training and strength training, but it’s fun because I had a goal. The goal was the Lycra catsuit…It was crazy to see it for the first time – everything all zipped up and all the weapons in there, bracelets on, the whole look. It was pretty sweet, I have to say.”

The actress also had to say goodbye to her favorite carbohydrates, too. Better her than us!
