U.S. Marine Corps enlistees conduct the pull-up portion of the initial strength test during a Marine Corps Recruiting Station Phoenix function March 2, 2013, in Gilbert, Ariz. The test was a requirement for the enlistees to ship to boot camp.
More than 400 enlistees and their family and friends participated in a daylong event that gave enlistees a preview of what to expect at boot camp. (DoD photo by Cpl. Tyler J. Bolken, U.S. Marine Corps) Original public domain image from Flickr
