Sure, being a Victoria's Secret model takes having a good figure, but starring in the summer action blockbuster Transformers 3: Dark of the Moon, takes more than just a pretty face -- it takes a strong body. Recently named the "Hottest Woman on Earth" on Maxim's annual Hot 100 list, Rosie Huntington-Whiteley got into action-star worthy shape for the new Transformers 3 movie.

Huntington-Whiteley credits her fit body to regular sessions with not one but two different personal trainers, along with firearms and stunt training. The new Transformers star, who is replacing the role of Megan Fox, says she also loves to box and regularly does cardio and strength training.
