Now, the Army is racing to approve significant changes to its legendary physical fitness test, the first revision since 1980, which will include offering soldiers an alternative to the leg tuck, a flash point for women, especially those who have given birth.At the same time, the new version of the test, which is required twice a year, does away with separate scoring curves based on gender and age. In its earliest rollout among 14,000 soldiers, 65 percent of a small set of women failed the new test, while 10 percent of men did.
