All about abs.

Do you need visible abs to be fit? Abs-olutely not. But if one of your goals is to carve out a six-pack, you know it's no small task. Like virtually every other fitness goal out there, it takes consistency and solid planning to achieve what's long been considered a milestone to many.

Today, we're putting a focus on abdominals, both from a strength and physique standpoint. Because remember: A strong core means a stable base for everything from your biggest squat and deadlift PRs to lifting a stubborn and very heavy dog into the car without injuring your back (speaking from experience on that second one).

We've got you covered with advice from legit experts, from a doctor of physical therapy to three-time Bikini Olympia champ Ashley Kaltwasser. Keep reading to get the lowdown on all things abdominals.

Ashley Kaltwasser's 6 Steps to Upgrade Your Ab Workout

Have you heard the phrase “abs are made in the kitchen”? I find this to be 100 percent accurate. Diet plays a major role in unveiling abdominal definition. But if you don’t develop solid muscle in this region of your body, you won’t have as much to show for your healthy eating choices.

Abs come in all shapes and sizes, with genetics playing a big role in their exact form. Some are wide, while some are narrow. Some are symmetrical, while others are “crooked.” These specific traits cannot be changed, but you can work with what ya got! You may naturally have a little extra flesh in the middle, but you shouldn’t lose hope. You may just have to work a little harder. Hey, we all have our strengths, weaknesses and unique beauty!

I try to work my abs twice a week. They can be trained in a short amount of time if you work them out efficiently. There are many bodyweight exercises that can be performed almost anywhere that can engage your core effectively.

Here are some of my top tips for tighter abs.
