Build muscle without lifting a finger?

No, this isn't like that informercial where they hooked those electrodes up to people's stomachs to build better abs. Scientists at Dartmouth have identified a gene that enhances muscle performance. According to researcher Lee Witters, "We now wonder if it's possible to achieve elements of muscular fitness without having to exercise, which in turn, raises many questions about possible modes of exercise performance enhancement, including the development of drugs that could do the same thing as we have done genetically. This also might raise to some the specter of 'gene doping,' something seriously being talked about in the future of high-performance athletes."
