Despite the fact that sit-ups been widely rebuked—everyone from Harvard Medical School to the U.S. Army advises against performing them—you shouldn’t discount the classic move just yet. The sit-up’s “primary function is to work your rectus abdominis, which are those six-pack muscles that most people want,” says Katie Barrett, lead instructor at B/SPOKE Cycling Studio in Boston and a certified personal trainer. “But doing that full sit-up is also going to work your hip flexors and other stabilizing core muscles.” The key is making sure you’re doing them correctly. (And here’s how to do just that).


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.
Lie on your back and bend your knees, placing a Swiss ball across your hips. With your hands on top of the ball and your body crunched forward as demonstrated, push your arms down as hard as possible for six seconds. The harder you push, the more the ball will resist you, giving your abs an intense stimulus. Exhale, relax for a few seconds, and then repeat.
To do it: Start in a plank position with one small towel placed under each ball of your foot, legs together. Bring your left knee in towards the right side of your chest, squeezing your abs. Then, straighten your right leg back out to full plank and bring your right knee in towards the left side of the your chest and back out to full plank. Next, draw both knees into your chest at the same time and then slide your legs back out to full plank. That’s one rep. Build up to 3 sets of 12-15 reps (resting in between). 

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.

Bent-Elbow Plank: This exercise works the whole trunk, particularly the transversus abdominis. Start by lying on your belly and then lift yourself up onto your toes and forearms (elbows in line with shoulders) while contracting your abdominals and keeping your back neutral. Hold that position for five seconds, then rest and repeat. Ultimately, strive to hold the pose for 90 seconds without any rest -- for one set. If you're more experienced, you can also do this exercise on your hands and toes. (As a beginner, start on your hands and knees with a neutral spine and simply contract the abdominals on an exhale without moving your back.)


A regular pushup works your core. A reverse pushup will work it so hard your abs will want to form a labor union. “When your legs fire your body forward, your core has to work extremely hard to decelerate your body,” says B.J. Gaddour, C.S.C.S., director of Men's Health StreamFIT. So this ab exercise not only works your shoulders and arms, but gives you a killer core workout at the same time.
5. Engage in resistance training aimed at your abs. In addition to eating right and losing weight, doing certain types of exercises can help you achieve a better-defined abdomen, Singer says. "I'm sure everybody knew somebody in high school who had tremendous abs who ate whatever he or she wanted and had tremendous abs without working out," Singer says. "Most of us aren't that lucky." If developing a six-pack is your goal, doing exercises aimed at your abs can be part of a successful regimen. Such workouts would include weighted crunches and weighted sit-ups, he says. Cardio workouts are helpful for shedding pounds, but won't, on their own, lead to defined abs.
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).

Let’s say it took you 15 minutes to do 100 push-ups in today’s training session. In order to achieve progressive overload, it’s enough for you to do 100 push-ups in less than 15-minutes in your next training session. This is why your training sessions will get shorter as you improve. The faster you complete your reps, the quicker you’ll wrap your training up and move on with your day. When I  got my six-pack abs, people couldn’t believe that I was training for less than a total of 2 hours a week. (Actually, it was closer to 1,5 hours).

Plank poses are very effective at tightening your tummy, whether you do these types of exercises in a yoga class or as part of your gym workout. The classic plank pose involves lying down on your stomach, then raising all your body weight up on your toes and forearms or hands in a “plank” position. You then hold the pose for as long as you can. You can change it up by doing a side plank (put all your weight on one forearm or hand and the sides of your feet), or by doing back leg lifts while in the traditional plank pose.
“You will not make more muscle by trying this route,” says McComsey. When you do cardio you’re burning calories, but you’re not stimulating your muscles to grow as you would with weight training. “The more muscle you have, the more calories and fat you’ll be burning,” he says. McComsey recommends hitting the weight room three or four days per week, with one of those days being a circuit with a variety of exercises. If you need to do cardio, try one day of 20-minutes of fast-slow intervals.
A. I’ll be honest, building muscle as a vegetarian is hard. There are nearly no clean sources of protein in a vegetarian diet. Soya Chunks come close but I’d recommend you stay away from a lot of soya if you’re a male due to it’s high oestrogen content. You can try incorporating more Beans (especially Rajma), Chickpeas, Hummus, Lentils (Dal), Sprouts, Tofu, Milk, Cottage Cheese (Paneer) and Cheese into your daily foods. Unfortunately, all of these foods either have higher carb content or higher fat content as compared to their protein content. Stick to the low fat or ‘made from cow milk’ variants.
Health fats is another valuable source in order to get lean muscles such as fish oils, raw nuts, olive oils and nut butters into your eating routine. These sources will keep your insulin levels stable, which is very salient if you will likely lose stomach fat and uncover well defined abs. I am not saying to go out there and eat a whole sack of Planters Cashews.
After having achieved this goal, there’s a seemingly big void in my life. I intend to fill it up with another ambitious goal instead of more training, though the latter is far more tempting! I find that training, staying fit, and eating right fits in very well with my lifestyle. I intend to keep it that way while being content with slow but lean and steady gains over time. I do intend on dabbling in boxing and advanced callisthenics in the future.
3. Beware of smoothies. Many of Hagensick's clients tell her they have a smoothie for breakfast. A typical smoothie could consist of a banana, a cup of spinach, one or two cups of mixed frozen berries and milk. Hagensick says she tells her clients to think about how many calories such ingredients total. "A half cup of frozen mixed berries is one serving of fruit. A small banana is a serving. You could have four or five servings of fruit, and each serving will have about 60 to 80 calories. That adds up," she says. "When you add a cup of low-fat plain yogurt, that's 100 calories. A smoothie could easily total more than 400 calories and you can consume it in a matter of minutes. If that's all you're having, you might end up hungry a couple hours later due to the spike in blood sugar from an overload of carbohydrates, and you could end up eating more over time than if you just had a good breakfast."
In order to get a ripped abdomen, you will have to focus on foods rich in high-quality proteins, antioxidants and Omega-3 and Omega-6. Having said that, increase your intake of seeds, chicken, nuts, fish (especially salmon and tuna), olive oil and eggs, which are particularly rich in proteins. Proteins are absolutely essential when you try to build muscle.
When guys talk about six-packs, they are really talking about one muscle, called the rectus abdominis. “The rectus abdominis runs from our lower ribs down to the top of our pubic bone, and fibrous bands of tissue break up the muscle along the way to give us the six-pack look we all desire,” explains kinesiologist David Cary, C.P.T., a T4 Coach at Equinox in Chicago. So, if you want to sprout six-pack abs, this is the muscle you need to work.
