Fast Track to a Flat Belly



Do the Slim Belly Workout moves on 3 nonconsecutive days to tone your midsection.


Do 30 to 40 minutes of cardio, such as brisk walking, swimming, jogging, or bike riding, to burn off belly fat. You should be breathing hard but still able to talk in short sentences.


Watch portions and fi ll up on whole grains, vegetables, fruits, lean protein, and healthy fats to maximize results. Aim for 1,600 to 1,800 calories spread evenly throughout the day. To keep tabs on your eating, go to prevention


Tony Caterisano, PhD, exercise scientist and professor in the department of health sciences at Furman University, designed this workout.


Do 3 sets of each of the 4 moves, performing as many reps (1 second up, 1 second down) as possible until you feel a burning sensation in the muscles you’re working or you can no longer maintain proper form. Rest 15 seconds between sets. You’ll likely be able to do more reps during earlier sets and exercises–and that’s okay. After you can do 50 reps or hold a plank for 2 minutes for most sets, try the “Make it Harder” variations, change the order of the exercises, or do the moves after another type of workout.

  1. Hipless Crunch

Lie on back with legs lifted and bent, calves parallel to fl oor, and feet relaxed. Cross arms over chest

with hands on shoulders. Contract abdominal muscles and lift head, shoulders, and upper back about 30

degrees off floor. Lower without touching head to floor. Exhale as you lift; inhale as you lower.

*Prevention Fitness Lab testers averaged 25 reps per set

Make It Easier:

Rest calves on a chair and extend arms down at sides.

Make It Harder: Extend legs straight up.


  • Don’t pull chin toward chest.
  • Focus on abs doing the work; imagine sliding rib cage toward hips.

Stop When…

  • You start pulling or jerking up with head, neck, or shoulders.
  • You can’t keep neck or shoulders relaxed.
  1. No-Hands Reverse Crunch

Lie face up with arms overhead and hands grasping a heavy piece of furniture or railing. Raise

feet into the air with legs bent. Contract abs, press back into floor, and lift hips off floor. Exhale as you lift; inhale as you lower.

Make It Easier:

Do the move with arms down at sides.

Make It Harder:

Straighten legs.
