Crunches have actually been proven to be one of the least effective ab exercises for you, so it's time to take them out of your workout. Of course, that doesn't mean your abs are going to be ignored, but you'll use even more effective movements to help you turn that flab into abs.

Here are exercises that are far better for you than crunches:

1. Kettlebell Juggler

The faster you go, the better it will be! This one works not just your abs, but your entire core as well. It's even great for a lower body workout, and it definitely deserves its place in your workout.

2. Skier Swing

Do this exercise with a pair of kettlebells or dumbbells, but go easy! It can cause back injuries if you swing too much, so make sure to keep your form tight as you swing those arms like a skier.

3. Three Point Core Touch

Talk about a core challenge! This is an incredibly difficult exercise that is not for the faint of heart, but it's amazing for toning your core, stretching your groin and increasing lower body flexibility.

4. Single Arm Overhead Press

Work out your core while shredding those shoulder muscles. Just using one dumbbell instead of two will throw off your balance, which forces your core to stay tight to compensate. It's great for your abs and side muscles.

5. Farmer's Walk

This is an oddly effective exercise. You do nothing more than grip two dumbbells by your side and walk. Sounds silly, but your core has to stabilize your upper body with each step you take. It's guaranteed to burn in no time.

6. Rotational Side Plank

Want to take it to the next level? Try this exercise, which focuses on your obliques while setting your ab muscles on fire. It's not for the faint of heart, but it's guaranteed to be far more effective than crunches.

7. Breakdancer

Take your plank to the next level by doing the Breakdancer. Your upper body never moves, but the shifting of your feet places an amazing strain on your abs. It's an ab blaster that works like a charm.

8. Kettlebell Hot Potato Squat

Squat, throw the kettlebell into the air, and balance all the while. It may sound like child's play, but it's an exercise that is guaranteed to have your core burning and shaking. Just be careful--throwing a weight into the air can be dangerous once you tire.

9. Plank

Sticking with the basics can work well. If you're a newbie, all the fancy exercises above may just be too tough for you. The plank is a great exercise that is simple and static so there's little risk of injury. Plus, there are awesome variations to make it tougher once you get the hang of it.

10. Swiss Ball Jackknife

Using a Swiss/exercise ball can make this exercise very intense, and you'll find your arms and shoulders are soon shaking along with your core.
