Bodyweight exercises always recruit more than one muscle group for each exercise so it is impossible to isolate and work one muscle group specifically by doing one type of exercise. It is however possible to increase the load targeting specific muscle groups with specific exercises so that they respond the most to the challenge. The following chart helps you find the exercise that helps focus more on specific abdominal muscle groups for best results. 

Why it made the list: Decline-bench crunches amp up the challenge by increasing the range of motion over standard crunches, and you can dial up (or down) the degree of difficulty by adjusting the angle of the bench. Adding a medicine ball or weight plate against your chest adds a further level of customizable resistance. This also allows you to manipulate where you want to fail: low, medium, or high reps.

This is exactly the type of article I was looking for. I’m female 5’1” and a runner. I weighed 115 until I started at the gym and now I’m about 118 but like the way I look better now because everything is tightening and I can already see some definition. I don’t have a lot of body fat but particularly I have a very thin midsection. I don’t eat clean but I do keep track of my calories and keep a balance. Honestly I don’t want to be any thinner and don’t want to lose my curves by losing any weight but I want abs! Any extra weight I carry on my lower body (which is why I run!). But I want abs without having to cut out my iced coffee! So as long as I keep up with my calories and keep a low body fat I can still get abs? I am ab training about 3 times a week. Sorry for the book! Lol! Just blindly trying to reach my goals on my own! 

This athletic move takes the plank to an all-new level. "It not only improves your core stability, but it targets muscles in your hips, groin, lower back, and often-neglected lower abs," says Durkin. Get your heart pumping by speeding up the movement, or hammer your core muscles by slowing it down. Either way, the exercise will boost your athleticism and will give you something to bare at the beach.
You can find myriad articles, blog posts and videos offering advice on how to develop a six-pack, the kind of chiseled abs you'd expect to see on world-class athletes, like Olympic gymnasts or swimmers. While Olympians and pro athletes developed their physiques by eating well and investing countless hours to working out, lifting weights and doing sit-ups and crunches, you could pick up a six-pack just by eating the right foods, these articles and videos suggest.
To do it: Stand with your feet hip-width apart and pressed firmly into the floor and hold a medicine ball (or other similar weighted object). Brace your abs in tight (as if preparing for someone to punch your stomach) and use your lower body to start the movement by bending your knees, sitting back into your hips, and reaching the ball down across the outside of your left leg. Stand up, swinging your arms across your body and up to the right while pressing your hips forward. Do 10-12 reps going from left hip to right shoulder, and then repeat on the other side.
How to: Start on the floor on your hands and knees. Lower your forearms to the floor with elbows positioned under your shoulders and your hands shoulder-width apart. Your arms should form a 90-degree angle. Maintain a straight line from heels through the top of your head, looking down at the floor, with gaze slightly in front of your face. Tighten your abs and hold. Do 15 reps.
I train 6 times a week with the only goal of getting stronger, lifting heavier and beating my previous records. I aggressively subscribe to the concept of progressive overload where you constantly challenge yourself by increasing volume, intensity, weight or a combination of those 3. This is the only way to continue building lean muscle as someone natural (one who does not consume anabolic steroids or enhancement drugs). I keep notes on how heavy I hit an exercise previously and new exercises I would like to incorporate for each muscle group.
Consuming more fat in your diet will actually help curb cravings after you’ve reduced your carb intake. “Fats help curb hunger because body takes longer to break down, use, or store fats,” he says. Hormones also play a role, especially when it comes to muscle-supporting testosterone. “Fats are needed to create and balance out hormones in our body to function normally,” McComsey adds.
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.
Spend a lot of money on expensive supplements and food — There are plenty of (rather expensive) supplements like plant protein powders and vegetarian meal replacement shakes. You might have to substitute more of solid food for these supplements to hit your ideal macro goals. As a vegetarian, you’re also not going to get in a lot of BCAAs through food so you might have to supplement with them separately. I’m not the one to tell you whether this is a good idea or not. If you can afford purchasing fancy food and supplements frequently, up to you.
In addition to this, you must also avoid sugary products (pastry, candy bars, coke etc), as sugar has a series of negative effects on your health, and it also contributes to belly fat which is the most difficult to get rid of!  Of course you will be tempted now and again so have a cheat day once a week when you can have your favourite “bad foods” but don’t go too crazy!
The next time you're at the gym, take a stroll. "The dumbbell farmer's walk may be one of the most underutilized exercises, and it's also one of the simplest to do," says Jack. Besides making it easier for you to carry heavy things—like luggage or those cases of beer for this weekend's party—the ab exercise challenges your core muscles to endlessly stabilize as the load shifts with each step. Plus, it will strengthen your grip, forearms, deltoids, and trapezoids—areas often neglected during workouts.
We live in an age where rock-hard, six-pack abdominal muscles are the goal of many workout enthusiasts. We all want that washboard look, but which ab exercises actually work? There are two sets of muscles to target: the rectus abdominis muscles (the ones you engage during regular situps, that run from your sternum to your pelvis) and the transverse abdominis (the deepest ab muscles that wrap around the spine and help stabilize your core).
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.”
Muscles exert higher EMG tension when they are contracting eccentrically (lowering the resistance) versus raising it; but the problem with most exercises is that the amount of weight you can lower is limited by how much you can lift positively (concentric work). This exercise compensates for the problem by changing the leverage during the lowering (eccentric) phase of the exercise.
Hi I’m 14 and a girl I know it’s young but I hate my body I’m currently 60.9kg saying it’s a healthy weight but I want toned abs so I can feel good about my body and not care about my face but I don’t want to lose weight because I’d be underweight and unhealthy , I have a bit of stomach fat and my normal routine is the 100 sit up challenge for 100 days , but I can never diet because I’m a very fussy eater i can’t eat brown rice or any vegetables the only healthy foods I eat is brown bread strawberries and oranges the rest is all junk but I’m wondering do I need to diet to see my abs because if not could you suggest things to do to help without dieting note I’ll be joining a gym soon but at the moment I’m doing home excersises sorry for the long paragraph

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.

Lie on your back with knees bent to 90-degree angles. Straighten your arms by your sides, and lengthen your fingertips. Press the backs of your shoulders against a mat, and slide them down away from your ears. Focusing on the deep waist muscles, inhale and slowly move your knees to the right, then exhale and return to starting position. Repeat on the left; that’s 1 rep. Do 5–8 reps.
To do the V-sit, start in a seated position on the floor, contract your abdominal muscles and core, and lift your legs up to a 45-degree angle as pictured. Reach your arms straight forward or reach up toward your shins as you are able. Maintain good core posture and a strong spine while you hold the position for several seconds. Rest and repeat several times. As you get stronger, hold the position longer.

How to use this list: Clayton suggests doing each exercise below for 30 to 45 seconds before every run. “This will fire up your muscles so they’re active when you need them most,” Clayton says. Clayton even demonstrates them herself, so you can nail the perfect form. You will need a mat and a set of sliders. Two hand towels or paper plates will work. too.
Build a strong back and sculpt a rock-solid middle in one shot with the archer row. This ab exercise combines a staggered side plank with a dumbbell row. "As the load moves up and down, your body has to fight to resist rotation," says Gaddour. That means your entire core—lower-back muscles, obliques, rectus abdominis (also known as your six-pack muscles)—is working overtime to keep your spine stable.
Ah the six-pack. The goal of most every fitness enthusiast. A tight, lean, shredded stomach not only looks great, but also feels great and builds more confidence. Let's face it, a chiseled midsection is something we all strive to strut. Unfortunately, not everyone is willing to put in the time and effort to build this work of art. For those that do however, the rewards are well worth the struggle.
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.
