The day gym in one of the most far-flung reaches of USMC Camp Pendleton is crawling with enlisted guys with time on their hands. After putting in a 10 hour workday, 14 E4's and E5's hump it into the gym, strip down and prepare for yet another workout in the quest for the Perfect Marine Corps body. Plenty of shower footage, lots of nude weigh-ins, jockstraps, bulging scrotums, flopping penises during a towel-fight... OW! You left a BIG RED MARK on me, stud!

Also included: some brief slo-mo video that was shot through the glass sunroof of the Navy softball team's locker room. Remarkably clear and totally amazing; this footage reveals younger squids getting naked and bounding around the locker room, tugging on their genitals in mock masturbation - but it's nothing but a semi-homoerotic display of male bonding. The smaller guys really work it. The bigger guys just let it hang there.
