The 8 Best Weighted Ab Exercises For a Stronger Core

Twisting in a plank position fires up the core and challenges your balance and stability. Holding a weight will work your upper body, too. If you’re struggling to keep up your form, ditch the weights and try this move with just your bodyweight.

1. Begin in a plank position with your belly button pulled in toward your spin and glutes tight while holding a five-pound dumbbell in each hand. Keep your wrists stiff to protect the joints. Open your feet a little wider than hip-distance apart.
2. Lift your left hand to the ceiling, twisting through your entire torso – keep the motion smooth and controlled. Your pelvis will rotate, but keep it level without letting it rise or drop.
3. Bring your left hand back to the floor, and repeat on the other side. That’s one rep.
4. Do three sets of eight to 10 reps.

This cardio move targets your core as well as the rest of your body – your shoulders are sure to feel it after just a few seconds.

1. Hold a lightweight dumbbell at chest height with your arms outstretched.
2. Run in place, driving your knees up toward your chest.
3. Keep your core engaged and chest tall while you drive your knees up.
4. Repeat for 30 seconds; rest for 30 seconds. Repeat for four sets.

This classic move is great for targeting your obliques. You can do it with your bodyweight alone or add a dumbbell or medicine ball to increase the challenge.

1. Holding a dumbbell in both hands, sit on the ground with your knees bent and your heels about a foot from your butt. You can also make the move more advanced by lifting your feet three or four inches off the floor, as pictured.
2. Lean slightly back without rounding your spine at all. It is really important, and difficult, to keep your back straight.
3. Pull your navel to your spine, and twist slowly to the left, bringing the weight to your left side. Keep the movement slow and controlled; focus on your ribs rotating, not your arms swinging.
4. Inhale to return to the center, then rotate to the right. That’s one rep.
5. Do three sets of 12 to 15 reps.

This compound exercise is a great choice if you want to engage your core and back muscles at the same time. You’ll work your core, challenge your stability, and activate the muscles in your upper back as you row while holding a plank.

1. Start in high plank, each hand holding onto a dumbbell that is resting on the floor. Step your feet wider slightly wider than your shoulders.
2. Pull your right elbow back, raising the dumbbell toward your chest, keeping the right elbow close to your torso, abs tight, and hips facing down.
3. Lower weight to return to plank, then repeat on the opposite side. That’s one rep.
4. Do three sets of eight to 10 reps.

This move challenges both the lower and upper abs to maintain torso stability while your arms and legs move away from your center.

1. Lie on your back with your arms reaching toward the ceiling, holding one weight with both hands. With your left leg bent and right leg out long, bring your right toes toward the ceiling. This is your starting position.
2. Lower your arms and leg toward the floor, keeping your lower back touching the mat.
3. Lift your arms and leg to return to the starting position. That’s one rep.
4. Do three sets of eight to 10 reps on each side.

This dynamic exercise works your obliques and upper abs while getting your heart rate up. Although this is a full-body move, it doesn’t require a lot of space, so you can do it almost anywhere. Use a five- to 10-pound dumbbell or a medicine ball.

1. Squat and twist left to hold the dumbbell on the outside of your left leg. This is your starting position.
2. Exhale and lift the weight diagonally across your body, twisting to the right until the dumbbell is above your head. Pivot on your left foot as needed.
3. Control the weight back to the starting position. That’s one rep.
4. Remember: You’re moving with force but also control. Don’t give in to the momentum of swinging the weight around.
5. Do three sets of 10 to 12 reps.

This plank variation will seriously challenge your core strength. Put your stability to the test and fire up your abs by lifting up each individual leg.

1. Start in a high plank position, keeping your hands directly underneath your shoulders.
2. With your back flat and core engaged, life your right leg off the ground and slowly rock your upper body backwards and forwards.
3. With control, place the right leg back down in a neutral plank position, and repeat with the left leg. That’s one rep.
4. Do three sets of six to eight reps.

This lunge variation works the entire body, and adding the twist ensures that your abs get a little extra attention. You’ll especially feel your obliques firing during this move.

1. Stand with your feet hip-distance apart. Hold a weight or medicine ball in both hands with your arms outstretched in front of you.
2. Take a large step back with your right foot, then lower your body until both legs are bent at 90-degree angles. As you sink into the lunge, twist your torso to the left.
3. Bring your torso back to center with your arms straight, and exhale as you straighten your legs. Bring your feet back together, and then step back on your left leg, twisting to the right. That’s one rep.
4. Do three sets of eight to 10 reps.
