This Workout Has the Secret to a Killer Core

Abs might be made in the kitchen, but that doesn't mean you should skimp on working your core altogether. Core work has many other benefits: It improves posture and athletic performance, curbs lower-back pain, and helps with your heart and digestive system. (See: 7 Benefits of a Strong Core.) In other words, challenging your core is a necessity—and this routine does just that.

Grokker expert Kelly Lee leads this workout to build core strength and trim your waistline. Paired with a HIIT or circuit training session, it'll deliver the results you've been dreaming of along with the added benefits. You'll be feeling it the next day, but work through it twice a week for a month and you'll definitely notice a difference. And if you still want more (though, we're not sure you will), try this Vinyasa yoga sequence for an added challenge.

Equipment Required: Dumbbells (optional—for advanced)
