Body by Glamour: The Summer Abs Challenge

Everyone wants flatter, tighter, more sculpted abs—whether it's bikini season or not—so we've created a supercharged workout engineered for serious results this summer and beyond. (Just give it two weeks!) Created by Anna Kaiser, who trains clients like Kelly Ripa, Shakira, and Sofia Vergara, this no-mercy workout features a suite of 12 moves that, along with a healthy diet, will deliver serious results. Complete the following sequence every other day for two weeks.

1.Ski Jumps

Beginning in a plank position, jump both legs in toward your left hand, keeping your legs and feet together. Then jump toward your right hand, lifting your butt into the air to hover for a second in the middle. That's one rep. Repeat this jumping motion from side to side, trying to lift your hips into the air as high as you can between landings.Reps: 10.

2.Twisted Sit-Ups

Lie down on your back with your arms extended behind your head, palms up. Use your abs to lift up as you sweep your arms out to your sides, bending your left knee in toward your chest and rotating your torso toward it. Reverse the motion back to the floor. Reps: 10, then switch sides.

3. Twisted Jackknife

Start in a plank position with your shins on top of a Swiss ball. Press down into the ball as you lift your hips toward the ceiling, then bend your knees in toward your left shoulder. Push the ball back out to a plank, then repeat the same motion on the right side. That's one rep. (Don't have a Swiss ball? Simply rest your feet on a towel on a hard surface and drag it along the floor instead.)Reps: 10.

4. Plank Double-Tap

Starting off in a plank position on the floor, tap your right toe out to the side at a 45-degree angle. (Make sure you're maintaining a perfect plank position.) Then bend your knee in and tap your right knee as close to your right shoulder as possible. Return to your plank position. Repeat on the left side—that's one full rep.Reps: 10.

5.Side Dip

Assume a side-plank position, resting your weight on your left side and left forearm. Anchoring your right foot on the floor, bend your left leg, holding the left foot against your right knee. Maintain that position as you dip your left hip to tap the floor, then raise back up again. Complete 10 reps, then switch sides. Reps: 10 on each side.

6.Tick-Tocks

Stand with your feet slightly wider than shoulder-width. Lower into a squat as you side-bend at the waist to your right, crunching your right elbow toward your right knee and reaching your left arm overhead. Press off your right foot and lean toward the left leg, bringing your right foot behind you as you reach back to tap it with your left hand, extending your right arm above you. Continue this tick-tock motion for 10 reps, then switch sides. Reps: 10 on each side.
