Bored of regular ol' crunches? Add these simple yet effective exercises to your next ab-day routine and you're guaranteed to feel so sore, it'll hurt to laugh.

Frogger

Begin in a plank position. Jump your feet to the outside of your hands, coming into a deep squat and keeping your hands on the floor.
Jump your feet back to a plank.
Really engage the abs by trying to slow down the jump, aiming to land the feet softly, without making a sound.
Continue for one minute.

Dumbbell Crossover Punch

Begin by lying on your back with your knees bent and your feet flat on the ground, about two feet from your butt. Hold weights, five- to eight-pound dumbbells, in both hands at your chest with your elbows on the floor.
Keeping your hands at your chest, roll up to a sitting position. Twist your ribs to the left as you "punch" your right hand to the outside of the left knee.
Bring the right hand back to your chest as you untwist, bringing your torso back to the center, and roll down to the ground.
Repeat the sit-up, twisting to the right side to complete one rep.
Complete three sets of 10 reps.

Double Crunch Pulse With Medicine Ball

Begin lying on your back with your legs in the air, toes toward the ceiling, holding the medicine ball over your chest with straight arms. Engage your abs to press your low back into the mat while lifting your head, neck, and upper back off the mat.
Exhale and round your low back so the bottom of the pelvis raises as you lift your upper body an inch higher off the mat. Aim the medicine ball toward your ankles as you perform this double crunch.
Inhale, and lower pelvis and upper back an inch toward the floor. Continue this slow pulsing motion for a total of 20 to 25 reps.
Complete three sets

Twisting Side Plank

Come into a side plank on your right side, with your feet stacked one on top of the other and your weight on your right elbow with your fingers reaching away from your body, palm down.
Place your left arm behind your head, and inhale to prepare.
Exhale and pull your navel to your spine to engage your deep abs and rotate your left rib cage toward the floor. Stay there for a second, and deepen your abdominal connection by pulling your navel in toward your spine even more.
Return to starting position, and repeat seven more times for a total of eight reps, then switch sides. Repeat series again on both sides.

Half Banana

Start lying on your back with your arms reaching toward the ceiling.
Exhale and roll up toward sitting while lifting your left leg up. Pause at the top and reach for your toes before rolling slowly back down to the mat. Then perform on the other side. This completes one rep.
Complete as many as you can with good form for one minute.

Butterfly Crunch

Lie on your back with your knees open and the soles of your feet together (in a butterfly position). Lengthen your arms overhead so they are resting on the floor.
Exhale and bring your hands and knees toward each other, performing a full-body crunch. Your shoulder blades should be off the mat as you perform a small reverse crunch, lifting your pelvis a bit off the mat. Hold this position for a moment and really feel your abs squeezing.
Slowly lower your arms and feet back to starting position to complete one rep.
Do as many crunches as you can in one minute.

Side-Plank Crunch

Begin in a side elbow plank with your left elbow down and your right hand behind your head.
Keeping your torso stable and your waist lifted, bring your right leg up toward your shoulder to lightly tap your right elbow.
Lengthen your right leg back to the starting position to complete one rep.
Do as many reps as you can in 30 seconds and then switch sides for another 30 seconds.

Elbow Plank With Hip Dip

From an elbow plank, slowly rotate the spine to lower your left hip to just above the floor (about one to two inches from the ground). Come back to elbow plank.
Now lower the right hip toward the floor. This counts as one rep.
Do as many reps as you can for 20 seconds.

Crunches on Exercise Ball

Sit on a well-inflated exercise ball.
Place your hands behind your head, and walk your feet away from the ball so your torso starts to roll onto the ball. The ball should support your hips and the curve of your lower back. Your legs should form a bridge with your knees bent at right angles.
Exhale and lift your upper body by about 45 degrees, pulling the deep abs in toward the spine, and return to starting position. Don't yank your neck!
Complete three sets of 10 reps.

Leaning Camel

Start on your knees. If this hurts your knees, fold up a mat or towel and kneel on that for a little cushioning. Your thighs should be parallel.
Hold a five- to eight-pound dumbbell with both hands in front of your chest.
Take a breath in, and as you exhale, lean back, squeezing your glutes, and use your abs to keep your spine straight. As you inhale, return your torso back to the starting position.
Repeat for a total of 15 times. Complete a total of three sets.

Overhead Circles

Stand with your feet hip-width apart with a slight bend in your knees. Keeping your spine in neutral, lift a five- to eight-pound medicine ball overhead.
Begin to circle the ball to the left, in the largest circles you can make, while maintaining a still and stable torso.
Circle eight times, then reverse directions for another eight reps to complete one set.
Do three sets.

Overhead Reach With Leg Lower

Lie on your back with your arms reaching toward the ceiling, holding one weight with both hands. With the sole of your left foot on the mat, bring your right toes toward the ceiling.
Exhale and lower your arms and leg toward the floor, keeping your lower back touching the mat.
Inhale and return to starting position to complete one rep. Repeat on the other side, and continue alternating for 20 reps total.

Coordination Fly

Lie on your back with a three- to five-pound dumbbell in each hand. Raise your arms straight up above your chest, with a slight bend at each elbow. Raise your legs up to tabletop, with knees and hips bent to 90-degree angles.
Inhale and open your arms to your side, with a slight bend at each elbow. Exhale as you bring your arms back up to starting position.
Once your arms are back straight, lift your upper back and curl up toward your legs, pushing your weights toward your shins. As you curl up, stretch your legs out in front of you.
Uncurl your spine slowly as you lower your upper body to the floor while bending your knees back to 90-degree angles. Once your head is back on the floor, release your arms to back out by your side, making sure not to let your upper arms touch the floor.
Do three sets of 15 to 20 reps.

High to Low Wood Chop

Holding an eight- to 10-pound dumbbell overhead, twist to the left, pivoting your right foot as needed.
Exhale, and slice the dumbbell across your body to the right as you raise your right knee, bringing the weight to the outside of your right hip.
Raise the weight back to starting position, and lightly tap your right toes to the floor. This completes one rep.
Do three sets of 15 reps on each side.

Lying Overhead Reach

Lie on your back with your hips and knees both at 90-degree angles, using your low abs to press your lower back into the mat. Holding five- to eight-pound dumbbells, raise your arms toward the ceiling, keeping the elbow joint slightly bent.
Reach your arms overhead, tapping the dumbbells on the floor above your head. Do not let your back arch away from the floor as you lower the weights.
Raise your arms back to the starting position to complete one rep.
Do 15 reps to complete a set. Do two to three sets.

Seated Russian Twist

Holding a dumbbell in both hands, sit on the ground with your knees bent and your heels off the floor.
Lean slightly back without rounding your spine at all. It is really important, and difficult, to keep your back straight.
Pull your navel to your spine, and twist slowly to the left, bringing the weight to your left side. The movement is not large and comes from the ribs rotating, not from your arms swinging. Inhale through center, and rotate to the right. This completes one rep.
Do 16 full rotations.

Plank and Rotate

Begin in a plank position holding a five-pound dumbbell in each hand, keeping your wrists stiff to protect the joints. Open your feet a little wider than hip distance.
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 raise or drop.
Bring your left hand back to the floor, and repeat this action on the other side to complete one rep.
Complete three sets of 10 reps.

Plank Jacks

Begin in plank position, with your shoulders over your wrists, your body in one straight line, and your feet together.
Like the motion of a jumping jack, jump your legs wide and then back together. Jump as quickly as you want, but keep your pelvis steady and don't let your booty rise toward the ceiling.
This counts as one rep.
Complete three sets of 10 reps.

Bicycle Crunches

Lie flat on the floor with your lower back pressed to the ground (pull your abs down to also target your deep abs). Interlace your fingers, and put your hands behind your head.
Bring your knees in toward your chest, and lift your shoulder blades off the ground.
Straighten your right leg out to about a 45-degree angle to the ground while turning your upper body to the left, bringing your right elbow toward the left knee. Make sure your rib cage is moving and not just your elbows.
Now switch sides and do the same motion on the other side to complete one rep (and to create the pedaling motion). Do this exercise with slow and controlled motion.
Complete three sets of 10 reps.
