How many pull ups can you do? Well, the workout is causing problems at the US Marine Corps boot camp.
A new physical fitness requirement was supposed to go into effect with the new year, but has already been postponed.
The rule requires female troops to complete 3 pull-ups, but after more than half of the ladies failed the test, commanders are re-evaluating the standard.
Military leaders say they are developing gender-neutral tests for combat roles, but some critics are worried that physical requirements will be watered down for female soldiers.
