Ab Meltdown | Burner

Everyone loves an ab workout—but you might not always have a whole lot of time to dedicate to getting that six-pack cut. You want to spend hours on the gym floor running through every situp and plank variation imaginable, sure, but when your schedule gets overwhelming, the limited time windows you have to work in a workout might discourage you from even performing one crunch.

That doesn't have to be the case—especially not if you ask firefighter and trainer Frank D'Agostino, N.A.S.M.-C.P.T. He designed this super-quick 10-minute routine to ensure that you'll never miss an opportunity to carve your core.
