Fave jeans a little snug? When it comes to banishing waistband bulge, the best strategy is to use moves that engage multiple muscle groups at once. Miami-based fitness expert Jessica Smith, star of the 10 Pounds DOWN: Cardio Abs DVD, designed this routine that combines calorie-torching cardio and super-effective core sculptors to help you melt that muffin top fast. Start today and in a few weeks, you'll be slipping into those skinnies with ease!
You'll need: A set of moderately heavy dumbbells (5-15 lbs, depending on your level)
How it works: Do 1 set of the recommended number of reps for each move back-to-back. Once you finish the last move, rest for 1-2 minutes and then repeat the full circuit 2 more times (3 circuits total). For best results, do this workout on four non-consecutive days per week (alternating with three days of your favorite cardio workout), in addition to a healthy diet.
