This Crazy-Effective Fitness Tool Fits in Your Purse


Urban Outfitters

Barely a few ounces in weight and bright violet in hue, gliding discs are the fitness tool equivalent of a barre class: They seem innocuous enough—even delicate—until suddenly your abs are quaking, there's a deep burn radiating from your glutes to your toes, and you're acutely aware of muscles you didn't even realize you had—doubly so the following day. All this, and you can stash them in an average-size handbag.

The secret is the way the fabric-covered circles challenge your balance: By sliding them under your hands or feet, you lose your grip from the floor and are forced to double down on your core strength in order to keep yourself stable. It's a convenient yet highly effective way to up the ante of classic bodyweight exercises like planks and bridges. In turn, you'll see results hand over fist.
