The reason: Classic ab moves like crunches and situps work the muscles that allow you to flex (that is, round) your lower spine. True core exercises, on the other hand, train the muscles that prevent your spine from rounding. They also allow you to transfer force from your lower body to your upper body (in a golf swing, for example), and vice versa.
Then, when it comes to sculpting those abs of your dreams, it’s not as simple as doing endless crunches. “Developing a six-pack requires more than just working the ‘pretty’ muscles that you can see,” Fitzgerald says. “The deeper, transverse core muscles must be strengthened first to create a strong, solid base—without that, only doing crunches can actually make your belly stick out more. Nobody wants that.”
That's because it’s insanely hard to get ripped abs. “Every woman’s body is built differently, so it varies, but generally speaking it takes a lot of time and dedication to get those abs to show,” says Amanda Butler, C.P.T., instructor at The Fhitting Room in New York City (and a fitness model who has her own fierce six-pack). “It can take anywhere from three months to a year to get a six-pack, and it’s not just about doing a ton of abs exercises.”
The starting position has you sitting at about a 45-degree angle and holding a medicine ball firmly with both hands in front of you. Start the movement by contracting your abs and slowly twisting from your torso to your right and tap the medicine ball on the floor beside you. Then quickly, but with a controlled motion, contract your abs and twist your torso and touch the medicine ball to the other side. Repeat 10-20 reps and rest.
We put this on the list because of how easy it is to manipulate the degree of difficulty. If a regular plank is too easy for you, lift an arm, or a leg—or an arm and a leg. Put your feet into a TRX and give that a whirl. Still too easy? Take your feet out, and put your forearms in. Each one of these progressions leads to a greater training stimulus to the abs.

Bicycle: This exercise works your obliques as well as your rectus abdominis. Lie on your back, hips and knees bent at 90-degrees, chest curled over ribs, hands behind your head. Extend the left leg out while bringing the right knee in towards the chest and rotating the left shoulder toward the right knee. Keep the arm from crossing the face. Rotate from the trunk through the center to the other side without dropping your chest. Move in slow, controlled movements without shifting your hips.
Building muscle and burning fat at the same time is the holy grail of bodybuilding but many people believe that it’s impossible. Here’s how it goes. Experienced bodybuilders first bulk then cut. Bulking is the period where they eat more calories than they burn (caloric surplus) in order to pack on muscle mass. Cutting is the period where they eat fewer calories than they burn (caloric deficit) in order to burn off the fat they inevitably gained during the bulk. The remaining muscle after bulking and cutting is their lean muscle gain.
Trainer tip: You know planks, right? It’s easy to go through the motions here. Don’t do it. “The key is to squeeze your entire body—quads, glutes, core, back, and fists—as tight as possible while taking diaphoretic breathes throughout the hold,” says Wealth. No matter how many times you’ve done it, this exercise is as difficult as you’re willing to make it.
Good news: Thanks to some of the best trainers in the country, we’re going to help you out. Below are their favorite abs exercises, along with a few pro tips to ensure that you’re executing each one perfectly. Incorporate them à la carte into your existing routine—or, if you’re feeling ambitious, turn all six into an abs workout circuit. Try two sets of each movement, resting for 30 seconds between each set.
“For me, getting a six-pack was about paying attention to what I was eating and lifting heavy weights at CrossFit. I do have a semi-strict diet, and I loosely count macros (focusing on daily carbs, protein, and fat intake rather than blindly counting calories) to stay balanced and on track. It sounds like a lot of work, but it really isn’t. Eventually, it just became a part of my lifestyle, and it’s something I enjoy doing. I even started a custom meal-plan business based on macros because I had such great results!” —Tina Haupert, @carrotsncake
