My job while in the USAF was to sit in the weightroom and watch men sweat. I assisted new members on how to use some of the equipment, made sure there were enough towels to mop up the sweat and try not to drool on the guys as they are pumping iron.
Downside: Late night sweat smells yucky.
Upside: Watching all the hot military guys work out. My military uniform was a pair of shorts and golf shirt. Plenty of time to study college courses.
