Cardio vs. Strength Exercises for abs

Cardio is what's going to get rid of the jiggle. Abs exercise will tone the muscle. I'd say cardio is most important at first...then increase ur abs exercise while continuing to do cardio. There's no point in building the muscle if you can't see it under the flub...

Also be mindful of the foods you take in. Some foods, such as pasta, rice and other sugary carbs/breads will make it harder for you to lose belly fat and/or cause you to bloat...

Short answer is both...however:

Diet is #1 priority. Your diet needs to be in check before you will ever see your abs.

You don't even need to do any crunches or core exercises to have abs. Everyone has abs underneath the fat. Doing strength exercises will condition them a bit.

You need to lower your overall body fat, but weight training the abs is important to build stength in them. I do weighted plank and weighted leg raises from a pullup bar a few times a week at least. Then again, i think everything should just be a balance of cardio AND weight lifting, regardless of which muscle group you prefer
