The crunch is the most popular abs exercise because anyone can do it. But that doesn't mean it's the best exercise for training your middle. "Crunches flex your trunk," says David Jack, owner of ActivPrayer in Phoenix, Arizona and creator of Men's Health MA40 Workout. "But the main function of your core is to prevent movement and resist force through your torso."

Leg day, arms day, chest-and-shoulders day. You already break up your regular workouts by muscle group; steal a page out of Alicia Vikander’s ab-shredding book and do the same to your core. To get ripped for Tomb Raider, Vikander broke her core workouts into three days: isometric (endurance moves, like planks); strength (sit-ups, hanging leg raises); and oblique-specific (told you so).
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.
“I alternate between all-out effort sprints (30 to 60 seconds) and walk/jog as a recovery until I feel fatigued. Intensity is key. Abs work as stabilizing muscles during a sprint, so the harder I push myself the harder my abs will work! Plus, there’s no equipment required, and I get a high calorie burn and full-body workout done in very little time. (I tell myself I can do anything for 30 seconds.) Depending on how I feel, I’ll either add this to the end of a routine or make it my entire workout, two to three times a week.” —Suzanne Cover, @suzannecover
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.
Eat carbs. "There's this notion that carbs are bad and that you need crazy amounts of protein to be lean and fit," says Alcantara, who disagrees, and eats just as much carbs as protein, although the ideal ratio varies based on your goals. "Whatever you eat to get the results you want has to be sustainable, otherwise you're going to end up right back where you started with the same habits that got you there."
