Gal Gadot for 'Batman v Superman'

Sporting a svelte figure for her breakout role in the "Fast and Furious" franchise, Israeli actress Gal Gadot unleashed the body of an Amazon warrior princess for her role in "Batman v Superman."

Gadot, who at one point was enrolled to become a lawyer in Israel, worked with American trainer Mark Twight for nine months (including three on location in Israel) to build muscle and strength for the role. The workout included a wide range of disciplines, including kung fu, kickboxing, swords and jujitsu.

According to Twight, by the end of the process, Gadot transformed her body from that of a model to a powerful high jumper. In a recent interview, the 30-year-old said she had gained roughly 17 pounds for the role. "All muscle," she added.
