“You’ve heard it before, but I’ll say it again—what you put in your mouth matters. It’s crucial to trimming up your core. You can do crunches for days, but if you aren’t fueling properly you’ll never see those abs! My favorite foods to snack on for flat abs are blueberries, apples, sweet potatoes, eggs, lean poultry, and green tea. ” —Amanda Butler, @amandabutlernyc

But alas, this process doesn’t happen overnight. And by now, the washboard abs industrial complex has produced such a dizzying volume of exercises, tricks, and gizmos promising to transform your midsection into a Hemsworth brother’s midsection that even after you’ve settled on a strategy, it’s hard not to wonder whether all that diligence and discipline is really making a difference.

First off, it's easy to sit back while doing this move, letting your hip flexors do much of the work. Second, if you keep a flat back, it limits the degree to which you can hit the upper abdominals—your back has to round! And finally, your hands should stay in the same relative position next to your head for the duration of the set. Letting them drift away on the eccentric and then pulling them back again beside your head brings a lot of shoulder and upper body into the move.
Lie faceup with feet flexed in the air so body creates a 90-degree angle and arms are rested palms down at sides. Use core to pulse legs straight up towards ceiling, lifting butt off floor and pushing weight into hands. Think about stamping the bottom of your shoes on the ceiling and avoid using momentum to swing legs forward and up. Lower back to floor and repeat.
Eat similar meals every day. "I pretty much eat the same thing, or substitutions that are very close to my normal meal plan, every day," Yobe says of her daily food intake, which includes a protein bar before her morning workout, a protein shake afterward, and two meals including chicken or fish, veggies like a green salad or bok choy, and a carb like rice, pasta, or potatoes. She also snacks on rice cakes with peanut butter, carrots, celery, and nuts. Although she admits this can be boring, the approach makes it easier for her to get all the nutrients she needs while remaining satisfied throughout the day.

How to: Lie on your left side with your legs straight and your right leg stacked on your left. Position yourself so your weight is resting on your left forearm and the outside edge of your left foot. Your elbow should be directly beneath your shoulder, and your upper arm should be perpendicular to the floor. Align your body so it forms a straight line from your neck to your ankles, and place your right hand in the air. Engage your core, and slowly twist your chest left, until it’s parallel to the ground. As you do this, thread your right arm through the space between your body and the floor. Raise back to start. That’s one rep. Do 15 reps on each side.
A common belief in bodybuilding is that a beginner can make progress lifting rocks. This is not to offend the brutally huge strongmen you see on the MET-Rx World’s Strongest Men on ESPN who lift those 350-lb. Atlas Stones but is to emphasize the point that beginners can make progress on just about any program, using just about anything for resistance, even small Flinstone pebbles. But just because beginners can have success with minimal effort and nonspecific workouts, this doesn’t mean that their training protocol will also work for an experienced athlete, or for someone who wants to go even beyond a “slightly visible” 6-Pack!
If the basic plank is too easy, after 60 seconds, add a few arm and leg lifts to the next 60 seconds. Every 15 seconds, alternate lifting one arm out in front of you while maintaining your posture for 10 seconds and repeating on the other side, and then switch to the legs. Lift the toes 5-10 inches off the floor and hold it for 15 seconds, and repeat with the other leg.
“If you need a small treat and indulgence per day, to keep you from overdoing it on the weekends,” says Shapiro, go for it. Just be sure to “stick to about 150 calories or less.” It’s a small trick to help you stay on-track. For a good sweet treat, consider dark chocolate (that’s a bar with a 70 percent or higher cacao rating). According to a study in Circulation Heart Failure, the flavanols within can slash your risk of heart disease by more than 30 percent.

For example, believing that you should eat your pre-workout meal is a great way to procrastinate with your training. What if you worked overtime and you don’t have enough time to eat your pre-workout meal? What if you don’t have enough money to buy supplements? All the items in the above list have the potential to evolve into excuses for procrastinating, or worse, quitting. Just forget about them and only do what matters. This will save you enormous time and willpower that should be spared for the things that actually matter in your quest to get abs.
Try starting your day off eating heavier, and ending on a light dinner. Instead of waking up and running out of the door with a banana, eating a small lunch, and then eating a hefty dinner, try making your breakfast your heaviest meal and your dinner the lightest. For carb intake at dinner time, try to ingest the wet types of carbs that are in high-water, medium-fiber foods.
Protein — The building block of muscle and that mystical term for most beginners. If you don’t consume enough protein while staying in a caloric deficit, you’re going to lose a lot of muscle mass along with that fat, drastically reducing your TDEE. More muscle means you can get away with eating more because muscles store glycogen which in turn give you energy. Also, more muscle makes you look more fab. Ever wondered why those people who go on a crash diet and lose a lot of weight gain it all back when they return to their old eating habits? Now you know!
Regular cardiovascular exercise should be an essential part of your plan. I recommend you try and get in three to five cardio workouts per week. If you find you’re not losing as much fat as you’d like then shoot for five sessions a week. If your progress is good then you might be able to get away with just three sessions a week. Adjust appropriately based on your rate of progress.
Fitness gurus know that the average person is lazy and will never put in the hard work to get six pack abs. If they manage to convince him that he already has six pack abs hiding under his belly fat then they can sell him their bullshit diet product. Since the average person doesn’t possess the necessary personal discipline and the diet knowledge to lose his belly fat, he never discovers that he’s been lied to. Hence the lie “abs are made in the kitchen” is perpetuated.
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.

Even though your rectus abdominus is the muscle you want to see when you look in the mirror, your inner core muscles, including your internal obliques and transverse abdominis, are the foundation for your six-pack. “You would not build a mansion on a weak foundation, so don’t try to build a six-pack on a weak core,” Cary says. This is when you’ll want to try out some more creative core workouts like planks, dead bugs, core twists, and farmer’s walks, he says. All of these tap your core’s ability to stabilize, rather than crunch, your core.

Do it: Stand with your feet hip-width apart and hold a dumbbell in your right hand, palm facing inwards towards the torso. Keep your back straight, activate your core, and then bend to the side as far as possible—but only at the waist. Hold for one second at the bottom of your range of motion, and return to start for one rep. Do between 12 and 20 reps for one set.
This way, you will prevent muscle exhaustion and injuries. There are several exercises for your abdomen that are highly efficient, such as the bicycle, Captain’s chair leg raise, exercise ball crunches, long arm crunches or the well-known crunch with heel push. These particular exercises are especially designed to stimulate your abdominal muscles, and they also involve several other muscle groups.  Vary the exercises and add weights as necessary to make sure you are always pushing yourself.
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.”
A University of Southern Maine study found that a single set of a weight-training exercise torches as many calories as running at a 6-minute-mile pace for the same amount of time. So for every second you spend lifting weights, your body is expending high amounts of energy. Add high intensity interval training (HIIT) principles to your workout, and you could see even more gains. 

Directions: Begin each of these workouts with a five-minute warmup, or go through the moves after you’ve done your usual cardio or strength training when you’re already warm. Each should also begin with 20 reps of what Fitzgerald calls “transverse pullbacks”—where you pull your navel toward your spine, as if bracing yourself against a sucker punch—as a way to activate the muscles for the work you’re about to ask of them. You’ll also need some dumbbells for some of these moves.
