Shred Your Abs With This 20-Minute HIIT Workout

The 30-Day Abs Challenge focuses on strengthening your core and sculpting your midsection. Get all the details on the challenge here.

When your goal is flat abs, you don't need to spend hours and hours doing mountain climbers, holding planks or crunching on a stability ball. The most efficient ab workouts are the ones that incorporate high-intensity interval training (HIIT).

Cut your routine down to snack-size and sculpt your abs with this routine from Elise Joan, Beachbody trainer and creator of Barre Blend. It only takes 20 minutes, and you can modify it to fit any fitness level.

The Workout

Do:​ 30 to 45 seconds of each exercise, resting for 15 to 30 seconds before the next move. Repeat the entire circuit once more (or twice more for a 30-minute workout).

  1. Halo Squat:​ Step sideways into your squat, then bring your hands around your head like you're making a halo.
  2. Shuffle Twist:​ Shuffle to the right twice, drop and twist to the right, then shuffle back and twist to the left. Continue alternating sides.
  3. Twisting Skater:​ Leap side to side, letting your back foot swing behind you. Drop your opposite hand to your front foot as you twist.
  4. Triceps Step-Up:​ Lower from high plank to forearm plank one arm at a time, keeping your core (especially your hips) stable.
  5. Burpee:​ Modify by skipping the jump or by lowering to your knees for the push-up.
  6. Goddess Squat to Curtsy Lunge:​ Step out wide with your right leg and lower into a squat. As you return to center, bring your right leg behind you and lower into a curtsy lunge. Repeat on the left, then continue alternating sides.
  7. In and Out:​ "Keep your knees slightly bent and your upper body as still as possible," Joan says.
  8. Crab Walk Shuffle:Crab walk four steps to the right, stand, then shuffle to the start and back, before repeating to the left.
  9. Hip Circle With Side Kick:​ Keep your core engaged as you work on your hip mobility.
  10. Core Jump:​ "Really try to get some height on these," Joan says, and land softly. Beginners can step or pulse instead of jumping.

The Cooldown

Do:​ at least 30 seconds of each stretch to bring your heart rate back down and relax the muscles you just worked.

  1. Low Lunge With Twist:​ From standing, step your left foot back and lower into a lunge. Place your left hand on the floor and twist to the right. Repeat on the other side.
  2. Half-Kneeling Hamstring Stretch:​ Kneel on your left leg with your right leg straight in front of you. Lean forward gently to feel a stretch in the back of your right leg. Switch sides.
  3. Pyramid Pose:​ Keep your legs straight and only fold over your front leg as far as you can go for a comfortable stretch.
  4. Wide-Leg Forward Fold:​ Fold from the waist and reach for the floor.
