NEW YORK (AP) — Gleaming abs abound in a new YouTube video about the making of the FDNY's 2014 charity calendar.
The "Calendar of Heroes" video is titled "The Brawn of the Brave."
A driving disco beat thumps in the background as viewers get a behind-the-scenes glimpse of the fashion-style shoot.
Among other things, the activities include bare-chested push-ups.
Several of the pin-up men take a break from their modeling duties to discuss the worthy cause.
Spoiler alert: A spray bottle enables all of that glistening skin.
Proceeds of the calendar benefit the FDNY Foundation.
