Demi Moore went from Bruce Williss hot wife to, while still hot, the ultra-toned and frighteningly fit Lieutenant Jordan O'Neil in G.I. Jane. The movie even shows this transformation, as ONeil is picked precisely because she is the most feminine and set up to fail. A few one-arm pushups later voilà shes a convincing Navy Seal. Whats surprising is that her feats of strength were not Hollywood gimmickry. She actually underwent military-style training in order to get ready for the role instead of traditional sculpting routines, according to celebrityfitnesstraining.com. Famously, she also shaved her head in order to completely rid herself of her beauty queen image. All Moore got for her troubles, besides a place in the heart of feminists everywhere, was a Golden Raspberry Award for Worst Actress. That and being healthy and stuff.
