Core exercises target the same muscles that crunches do — but they also include your hip and lower-back muscles. So what's a true core exercise? One that trains you to keep your spine stable and in its natural alignment. Besides the plank (more on that in a minute), scores of exercises qualify, including the side plank, mountain climber, rollouts, hollow body holds, and even the pushup.
So let's get to it. Here are the experts' choices on the most effective abdominal exercises. These should be performed two to three times weekly (for beginners, two is plenty to start). Each exercise should be executed until the point of momentary muscular failure, which should happen between 30 and 90 seconds. This is considered one set, which should be no more than 15 to 20 repetitions. Rest for 30 to 60 seconds. Concentrate on performing each exercise slowly with good form. Work up to completing two to three sets of each exercise.
Try adding four or five to the end of your workout to challenge your core a little more, or turn them into a standalone workout—try doing 12-15 reps of each exercise and then repeating the circuit (of four or five exercises) three to four times, to start. If you feel tension in your lower back during any of these exercises, stop and reset, making sure your abs are really engaged and that your back is not arched. You can also try starting with fewer reps. If you still feel discomfort, skip that exercise and try a different that allows you to keep your spine in a safer position. (It's also helpful to read up on which abs exercises tend to be irritating for lower-back issues beforehand if that's a concern for you.)
But if you’re searching for lower abs exercises, we need to get one thing out of the way first: “Lower abs exercises” aren’t really a thing. “Your core is comprised of the rectus abdominis, which runs down the front of your body and creates that ‘six-pack’ effect; your obliques (side abs); your erector spinae, which runs up your back; and your transverse abdominis (the deep core located under those six-pack muscles),” says Lindsay Clayton, a certified run coach and trainer at Barry’s Bootcamp in New York City. “When people point to the lower part of their stomach and say their ‘lower abs’, they're really just referring to their rectus abdominis, and you can’t only work the lower part in isolation.”

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.

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.
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.
