Rock Your Abs: 5-Minute Workout
Work your abs while standing for a functional workout that actually strengthens your core for activities in your life. Plus, you'll create a sleek midsection with these moves that also work your entire body. We've added some weight to this workout, too, to make it even more effective. We suggest a dumbbell between three and eight pounds — yep, you only need one!
Directions: Perform each exercise for 30 seconds, then repeat for a second round.
