This 15-Minute Ab Workout Uses a Stability Ball to Build a Shredded, More Functional Core

Before you chuck that dusty old stability ball from your garage into the donation pile, hear us out. You might think they’re just for fitness influencers or older adults in aerobics classes, but stability balls offer so much more than meets the eye. Exercising on an unstable surface forces your body to constantly adjust, creating continuous communication between brain and body through proprioceptors. This compounds to boost coordination, reflexive stability, and positional awareness over time.
